The 1080p input lag of the Sony X850C in game mode is good, but nothing exceptional. Outside of game mode, the input lag is surprisingly low - even when turning on the soap opera effect.

Update 10/26/2016: After the Latest firmware update (PKG3.531.0108NAB), the HDR input lag has gone down from 94ms to around 58ms, which is a good improvement and should be good enough for casual 4k HDR gaming.

Update 12/16/2016: A new firmware update has been released to upgrade the TV to Android Marshmallow. This has reduced the 4k input lag (including HDR). When in HDR mode, the TV can't display chroma 4:4:4 accurately as it is forced into the 'HDR Video' picture mode.

Conclusion Amazon.co.uk CHECK PRICE Right

The Sony X850C is a great 4k TV. It has deep and uniform blacks, little motion blur, and great 1080p upscaling. The input lag could have been better for gaming though, but because of its good backlight control, it is still a great gaming TV.

Additional Review Notes

Differences between sizes

We reviewed the 55" (XBR-55X850C). It is the only size that is edge-lit. Bigger sizes usually have worse black uniformity, but that shouldn't be the case here due to their direct backlight. If someone finds another significant difference between sizes, let us know and we will update our review.

Overseas, the 43" version (43X8500C) has an IPS panel (as reported by one of our visitor, who took this picture).

Motionflow Clearness

Instead of last year's Impulse mode, there is now a slider called 'Clearness' that changes the duty cycle of the backlight flickering. Increasing 'Clearness' reduces the duty cycle, making the picture clearer, without motion interpolation (the soap opera effect). The frequency of the flickering stays the same, though (120Hz), except when it is set to the max, where it drops to 60hz.

Using this feature darkens the picture and also introduces some visible flickering, so it is not for everyone. This can be used in game mode, as it doesn't significantly increase input lag.

Here are the pictures of the different values, as well as where the Samsung JU7100 fits visually.

The Sony X850C has a 7.9 rating while the Vizio 2015 TV's all have 8+. Are the Vizio's actually better TV's, with better picture quality? I find that hard to believe, but your rating suggests it to be so.

Our overall score is a weighted average of our individual tests, so yes, overall, Vizio TVs have better picture quality.

But you shouldn't look at the overall score to decide on which TV to buy. Instead, look at the elements that you care about, for your own needs. For example, you might not care about the 720p upscaling or the input lag, so in that case, the X850C would be better for you than Vizio.

First off, great reviews! Very informative. I purchased the 65x850c this week. The picture and set are amazing, but there is light bleeding on both sides (about an inch) of the unit ONLY during medium bright scenes. Dark/black and bright scenes don't have this issue. It also has some vertical banding against sky scenes when panning. Should I exchange? Many thanks, and keep up the great work!
Yes. Neither of those things is normal, so get a new unit.

I'm using Sony TDG BT500A 3D glasses, which work well. I tried Playstation RF glasses and some I got with a Sony HW50ES, neither of which worked. Are you sure the 3D glasses in the links above will work?
The HW50ES has compatibility issues with other 3D glasses, and people have complained about the incompatibility of the Playstation RF glasses. The ones we linked to should work fine.

I heard before that Sony TVs with low-quality videos (480p and 720p) look bad. Now I see in your review that the 480p video score is 7/10. Most likely this score is for all Sony TVs, right? Would even last year's w600 or w800 models score 7/10 for 480p movies?

It's very likely that the other Sony TVs we test will have the same upscaling capabilities, but we'll only know once we've tested a couple more TVs. Unfortunately, we didn't test for upscaling with last year's TVs, so we can't say how the W600B or W800B compare.

Update: We just finished testing the W800C. It doesn't have the upscaling issue that the X850C does.

Update: The latest firmware update fixed the issue on the X850C. We updated the review.

18
I'm thinking of purchasing this TV, but Sony said they would support HDR via a future update with the x85c series. Does that include this set? Thanks!
Even if it does support it, it won't be able to do HDR very well, though, because it doesn't have local dimming, so it won't be able to have very bright highlights.
16
I bought the 3D glasses you posted and they work fine, so I bought an extra pair, but these don't seem to work. It's the same glasses. Could I be doing something wrong?
Did you insert the battery and power the glasses on? If you did both and the other glasses are working, but this pair isn't, then it's likely a defect, and an exchange will be necessary.
15
How do you think this compares to last years' X850B?
We didn't review the X850B, so we can't really compare them. The 60" and 65" versions were IPS, so the new X850C has better contrast, but a more limited viewing angle.
14
Can the X850C upscale 1080p in a direct 1 pixel to 4 pixels way?

No, not even in game mode, but it is very close. Here is a picture of a single white pixel on a black background at 1080p, in game mode and custom mode.

Will Sony ever include the ability to connect as a fully functional computer monitor? 4:4:4 @ 60 hz. Samsung is doing it. Why do they alienate that niche?
Chances are, it's so that they can cut costs by reusing old HDMI chips. We can't really know for sure, though. Hopefully that's something they explore in the future.
Update: With the new firmware update PKG2.463.0010NAB, this TV now supports 4k @ 60Hz @ 4:4:4. To enable this, go to Settings - External Inputs - HDMI Signal Format - Enhanced (new).

Would you mind sharing the details of your weighted average calculation of the final score? Which sub-scores are included and which weight are they each given?

Here are the current sub-scores included, as well as their weight. In short, it is only the results related to picture quality that count, as well as the input lag.

Black Uniformity5
Gray Uniformity4

Motion Blur10
Input Lag7
Average Room10
Bright Room10
480p Upscaling10
720p Upscaling10

3D1

Note that we are always tweaking the weighting and tests based on feedback we receive, so that our results can better represent the things people care most about. For example, that's why the 3D picture quality score only has a weight of 1; most people don't care about it. Also, black uniformity and gray uniformity, while very important, only have weights of 5/4, because the variance between units for these scores is big (we could have gotten a unit that is better or worse than average, and so our score could misrepresent the series).

Feel free to share feedback on this.

Update: We completely changed the scoring. More details here.

Can you post the color data for this TV. It would be great to see how it compares to the JU7100 and the JS8500.
Yes, we will update all our 2015 reviews with the color tests over the course of the next few weeks.
11
I recently purchased the 55" X850C and over the past few days I've noticed there's a handful of small areas (mostly in the lower right quadrant) that when displaying white, or another light solid color, are noticeably brighter than the rest of the picture (here is a photo of the issue: i.imgur.com/PrFqkkk.jpg). I'm coming from a 2006 60" Sony XBR SXRD, so I was curious if this is an issue common with all modern LED screens, or if I may simply have a defective unit?
Uniformity issues are common, but something like that is a defect. You should get it exchanged.

Hello, I just noticed Sony is putting out an X810 model without 3D. Do you see much difference between the 810 and the 850? Looks like the 810 is also direct-lit as opposed to edge-lit. Thanks.
We won't know how they measure up until we test the X810c in a few weeks.
Update: The review is up.

How high can the backlight go with clearness 5 or the other settings? It'd be nice if they put some more power into the backlight so you can compensate for the brightness loss.

Here are all white luminosity measurements, for a backlight of 5 (the settings used in our review) and max.

It is also worth noting that the flickering is only really noticeable on clearness 5, not really on the other ones.

8
Is the 65" model better than the 55"?
They are most likely the same. The 65" is direct lit, which usually means a better overall uniformity, but often comes with more dirty screen effect due to the localized dispersion of each LED behind the screen (which, for example, can be seen on the Samsung JU7100 or the Vizio M).
8
Does the Sony x850c have 2D to 3D conversion?
No. We checked several of Sony's 2015 TVs and none were able to convert 2D to 3D.

I noticed in a few reviews that the type of HDMI cable used had an effect on the test results achieved in testing. Any recommendation for HDMI cable specs to use with the newer sets (4K in general), more specifically the X850C or JU7100?

For most usage, the HDMI cable doesn't matter at all, so just buy the cheapest one you can find. However, if you do plan to do 4k @ 60Hz @ 4:4:4 (which the X850C can't by the way, but the JU7100 does), then it matters, because that requires a very high bandwidth and some cables are not able to support it

We initially bought a Monoprice Redmere cable to test 4k @ 60Hz @ 4:4:4, because the specs said that the bandwidth was supported. Unfortunately it didn't worked. But surprisingly, a cheap AmazonBasics HDMI cable (like this one) worked.

At that high bandwidth, interference is a big issue. The Redmere cable is really thin, so it probably has less shielding. The AmazonBasics one is really thick and ugly, but that's probably why it was able to handle the faster speed.

Update: With the new firmware update PKG2.463.0010NAB, this TV now supports 4k @ 60Hz @ 4:4:4. To enable this, go to Settings - External Inputs - HDMI Signal Format - Enhanced (new).

8
Does this TV support HDMI 2.0?
It supports some HDMI 2.0 features, so it is labelled as being HDMI 2.0. It can't do 18 Gbps, though, so it's not full HDMI 2.0.
Update: A firmware update has corrected this. The TV now supports HDMI 2.0a.

Someone earlier asked about an updated review on the unit with the latest firmware updates. Your response was there would be no changes, however working in the retail environment I have noticed huge differences in the way the TV smart features function, as well as the upscaling and color control.
The last two firmware updates list these improvements.
File Description UPDATE System Software Update Release Date 7/15/2015 Version PKG2.287.0010NAB File Size 1.04 GB
DOWNLOAD
Sony has designed the BRAVIA Televisions software update process to be customer friendly. This software update (version PKG2.287.0010NAB) provides the following benefits:
Improvements over version PKG2.237.0010NAB:
  • Supports PlayMemories Online service
  • Supports PlayStation Now service
  • Improves Wi-Fi connectivity of the TV
Benefits provided by previous updates and included in version PKG2.287.0010NAB:
  • Improves picture quality (dynamic range, noise reduction, sharpness)
  • Supports Netflix streaming service (4K Models)
  • Improves Lip Sync for HDMI input
  • Improves performance and stability of the USB video playback features
  • Improves general performance of the TV
  • Resolves a condition where a black screen and no sound may occur when an input changes from YouTube to another input
  • Resolves a condition where a black screen may occur during USB video playback
  • Supports Internet based EPG (Electronic program guide)
  • Supports Netflix streaming service (2K Models)
  • Supports Amazon, Pandora, and Crackle applications
  • Supports Force Reboot by holding down the Power key on the BT or IR remote controller
  • Improves performance and stability of overall UI operation
  • Improves performance and stability of the Action Menu

Before that was 2.237 firmware, and it said it fixed black level and dimming from a re-calibration of TV's hardware. From the look of the TVs within a store environment, the TVs you recommend over it don't look nearly as good.
When we test TVs, things like noise reduction, lip sync, and USB stability (to pick just a few examples from above) are not included in our scoring. The only elements that we score that are likely to change are the upscaling (for which we did update the score), and the input lag, which did not change.
So, just to clarify, we're not saying that firmware updates don't improve certain elements of the TV. We're saying that the overall, unprocessed picture (which is what we care most about) is minimally affected by firmware updates, and so we won't be retesting our TVs when updates are released.
Comparing TVs in a retail environment also doesn't tend to give an accurate idea of how they stack up to each other, so we don't think that comparison is what most people should use when purchasing a TV.
Thanks for writing in, and for listing some of the improvements made by the firmware update. We're sure other readers will find them interesting.

I just received my UN75X850C and all corners of screen have black shadowing during light color screens. Especially noticeable with whites. Is this a normal thing with larger TVs?
Yes, it's unfortunately pretty common. It shouldn't be bad enough that it ruins your viewing experience, though. If you'd like, you can send us a photo of the problem and we can tell you whether you should return the set.
7
I've compared pictures of 480p videos of x850c and j6300 but according to your pictures, it looks like Sony is better and Samsung is a little more unclear. I wonder why you gave Sony 7 points and Samsung has 8 for this test?

It is great if it is what you like, but you can get the same processed look on every TV by increasing the sharpness setting. For example, here is a picture of 480p on the J6300 with sharpness increased to 50. It now looks closer to the Sony X850C.

The problem of the X850C is you can't remove the over sharpness on 480p input. Therefore, it is an issue for people who don't like the sharpness look and prefer a more natural picture.

Did you guys get a chance to calibrate? If so, what settings?
Yes, here are the settings we used.

Would you consider reviewing the 65" version of the Sony X850C? The reason being that the 65" version is direct-lit and, as a result, I think the results that you would get would be different, particularly on the gray uniformity test. I went through full screen colors ranging from pure white to pure black to the colors like magenta and cyan in between, and they appear to have nearly perfect uniformity across the board. It might be significant enough that representing the whole X850C series by the 55" version is misleading.
Thanks for all of your hard work!
Unfortunately, it's very unlikely that we'll review a different size of the X850C. Many TV lines have this sort of difference between sizes, and we don't have the time to explore them all. It wouldn't be fair for us to review the 65" size for this TV and not review other models that have differences across sizes. With the possible exception of the uniformity, we expect the rest of our findings should remain valid for the other sizes.
Thanks for sharing your experience with this TV.
6
Does this TV have the ability to zoom? For example, if I wanted to make a 16:9 movie take up more of the screen, is there a zoom function that will let me do so?
The 'Wide' button can do that, though we've noticed that it doesn't work with the TV's built-in apps.
6
I remember reading in a reply somewhere you said you apply light pressure with a clothe to new LEDs. I can't remember the technique or why you do it (uniformity?), but I am getting a 55" Sony X850C delivered soon and wanted to see if you could go over that. Thanks
It is to improve the black uniformity. LED TVs are very sensitive to a slight variation of pressure in the panel, so a simple trick that often works is to just slightly stroke the screen. We should probably do a video on how to do it. In short, you barely touch the screen, and do big long stroke. Keep the TV on while doing it and display a black scene, so you can see if it helps or not. You might want to try different stroking pattern too.

Dear RTINGS: This is in response to the question you responded to on June 24th regarding the situation of the X850C not supporting 60 hz 4:4:4 chroma. I have recently purchased this tv, and Sony just sent through a software update on August 22nd. The HDMI hardware was capable of 4:4:4, but such feature was not activated. This new update has now given this set the 4:4:4 feature. It is under Settings -> External Inputs -> HDMI Signal Format -> Enhanced (new). It will state it can display 4:4:4. Hopefully this info will be helpful to those who are interested in this tv. As always, thanks for your reviews, and thank you for answering a previous question of mine.
Thank you! This is great news. We updated our X850C to the new firmware #PKG2.463.0010NAB and it does indeed work. We updated the review with this information. We will retest and update all our 2015 Sony TVs for this. Thanks again.

For some odd reason when trying to run 4k 60hz 444 with enhanced format enabled after latest firmware update, my PC being connected to HDMI port 1 is saying no signal. And the video card I'm using is a 980ti with HDMI 2.0. So I find it strange that it's not working at all. Is there something I missed on the tv?
This is most likely your HDMI cable that doesn't support that high bandwidth. We had the same issue happened to us on some of our cables (even the ones rated HDMI 2.0!). We found that the thicker the cable, the higher the chance it handles 4k @ 60Hz @ 4:4:4. For example, the thinnest HDMI cable we have (Monoprice Redmere 15 ft rated at HDMI 2.0) doesn't work, but our very thick cheap AmazonBasics HDMI 1.4 20ft works perfectly.
6
Can you,in the future, list what version od HDMI the ports are (1.4 vs 2.0)? I know pretty much all TVs released this year and beyond have HDMI 2.0, but not all ports are 2.0, some are 1.4 and only one is 2.0 (like the Vizio M series). This is important to me because I would (in the future) have multiple 2.0 devices hooked up like a PC and a 4k blu ray player.
Yes, this is something we plan to add to our reviews. Thank you for your suggestion.

Could you explain the Film Mode setting and what the different options actually do? Does your suggested setting of "High" introduce any soap opera effect or other artifacts?
It changes the aggressiveness of the reverse 3:2 pulldown as well as the motion interpolation (soap opera effect). By itself, it doesn't introduce any soap opera effect, but when used in conjunction with MotionFlow to Smooth, it can increase the pattern matching. Low will only help for judder (reverse 3:2 pulldown, in conjunction with MotionFlow to TrueCinema).
The downside of using that feature is it can be too aggressive depending on what you are watching. For example, it might try to remove judder where there is none (like in real 60p content), which creates judder.

Stuck between the 55" Models of the Sony X850C and Samsung JU7100 for my Man Cave. It will be used for watching sports, movies, and playing Xbox One. Which TV should I get? Also, does it make more sense to wait a little while for the HDR TVs to drop in price? Thanks in advance!
You should get the Samsung UN55JU7100. Both it and the Sony X850C have similar picture quality, but the JU7100 has lower input lag, which you want for gaming.
As for HDR, there's not much point in waiting. There's still no standard for what HDR is (meaning different TVs labeled as being HDR may not actually be HDR once all is said and done), and HDR content is still extremely limited. You might as well get yourself a TV you like now.

My purchase has come down to one thing: upscaling 720p. It's between the 65" X850C from Sony and the 65" JU7100 from Samsung. I've seen the Sony's display in a store and every thing looked off when I was watching ESPN.
Which of these would be my best bet, and whats the best way to do the upscaling? Have the cable box upscale it to 1080p, or have the box send it out in 720p and let the TV do all the work? Thank you in advance for your time.
It's impossible to get an accurate feel for the look of a TV based on what you see in stores. Both the Samsung JU7100 and the Sony X850C are about equally good at upscaling 720p, but the JU7100 has less motion blur. That's good for sports, so we recommend going with that TV.
You're better off letting the TV do the upscaling. If you used the cable box, it would be upscaling the 720p signal to 1080p, and then the TV would have to upscale that to 4k. Less mismatch is better (upscaling isn't lossless, so each step changes the image a bit), so you should should skip that step and let the TV do all the work.
5
Any word if the x850c will be updated to HDMI 2.0a to allow 4k @ 60hz 4:4:4 chroma? Thanks for the post, great info here!
Very unlikely because it is a hardware limitation, not firmware.
Update: With the new firmware update PKG2.463.0010NAB, this TV now supports 4k @ 60Hz @ 4:4:4. To enable this, go to Settings - External Inputs - HDMI Signal Format - Enhanced (new).

I bought the 55" version of this TV and ultimately love it. The overall picture quality and colors are incredible! Netflix 4k has been great. Blu-rays look great. That being said, I have noticed that there is slight clouding in two parts of my screen, but it's only noticeable with space scenes or when the screen is entirely black.
It's something I can totally live with, but kind of bugs me at the same time. I know that black uniformity issues are common with 2015 LCD,s but considering the black uniformity rating of 9.5 for this TV, I am wondering if I should return it for another set, or if I can expect some clouding no matter what set I get? It's not bright clouding by any means - just a decent-sized spot that I want to make sure is within the normal range for this TV. Any guidance is greatly appreciated!
If you're unsure, email us a photo of your screen displaying our black uniformity image (black frame with the white cross) and we'll let you know if the issue is within acceptable limits, or if you should make a return.

Hey guys. I bought one of these sets and noticed there is a lot of banding, pixelation, and noise in dark areas and dark colors and was wondering if your set had these problems. I never noticed any of these problems on my W950B. Do you think that I got a bad set and should exchange it?
You probably don't have a bad set. First, make sure 'Reality Creation' is Off then set 'Sharpness' to 50 and 'Digital noise reduction' to Medium (you can try High as well but it may soften the picture too much). See if it's any better. For the banding issue, unfortunately, there is no settings to alleviate this.

What type of processor does this TV have? I see Samsung with quad core processors advertised and Sony does not display that information, even on their home page.
TVs do relatively little compared to a PC, so it isn't as important to list the kind of processor. Still, the type of processor can be an indication of how fast the smart platform will operate. Unfortunately, that information isn't listed anywhere.

I mainly use the TV as a comp monitor. Does this support 4:4:4 chroma at 2160p@60hz?
No, it only supports chroma 4:4:4 4k @ 30 fps. One TV that does support 4:4:4 4k @ 60hz, and is a comparable price, is the Samsung JU7100.
Update: With the new firmware update PKG2.463.0010NAB, this TV now supports 4k @ 60Hz @ 4:4:4. To enable this, go to Settings - External Inputs - HDMI Signal Format - Enhanced (new).

I play both console and PC games hooked up to my TV, and like my TV to look great with both, since I do not have room for an additional standalone PC monitor. I have been considering the Sony X810C and the X850C primarily because they appear to be great as PC monitors for gaming and can take many different kinds of input.
Couple quick PC Monitor related questions:
1: I notice that the Sony 4K lineup can do 1080p @ 120hz and 4k @ 60 hz @ 4:4:4, but what about 1440p? Could I set my PC to display 2560x1440 to the Sony TV and achieve 120hz (or even 60hz)?
2: How bad is the "dash artifacts" issue while using 1080p @ 120 hz? If I am going to spend $1,000+ on a TV, it would be a bummer to have the 120 hz have noticeable problems and look worse than my old LG.
Thanks! Great website!
They can accept a 1440p120 and a 1440p60 signal, but the image gets very blurry (even in Game/Graphics mode), so it's not worth doing.
We didn't notice the dash artifacts at all when we initially tested for 1080p120 capability, so they're not that noticeable generally. On a very dark background, though, they'll be pretty noticeable.

Now that you have a way to test for 10-bit panels and a gradient, is this X850C an 8-bit or a 10-bit panel?
It's 10-bit, and produced one of the smoothest gradients we've seen so far.
3
My primary use is going to be sports, movies and video games in that order. What should I go with? The 65" Sony 850C or 70" Vizio M Series?
Both TVs have good contrast and uniformity, but the M has a bit too much blur to be good for gaming. If you want something that will look good for all of your uses, the X850C is the best choice.

I was really considering purchasing this model television, and when I visited the Sony website, I noticed this model: Sony XBR65X800B. It is labeled "new," and I am confused, since the numbering would suggest that it is an older model. Do you have any clarification on this? If so, it appears to be a much better cost-effective option. My main concerns are gaming and movies. I really don't care much for 3D. Any input would be greatly appreciated.
It's a 2014 model, but it's one that we did not review. Because of that, we can't say with any certainty just how it performs for gaming and movies.

I have had the Sony XBR55X850C for about 7 weeks and am trying to update to the most current firmware PKG2.463.0010NAB. Love the TV but it gets to about 85% and says try again later even tried to do it from a down load to thumb drive and said the same thing. Called Sony and they said maybe a bad update on there end, try in a couple of days. Any advice would be appreciated.
We haven't had that problem when we updated ours last Tuesday via WiFi. Maybe you downloaded too many apps already? You could try resetting your TV.
3
Am considering the Sony 75" 850C & Samsung 75" JU6500. I am nervous about the judder issue with the Samsung. Which would you recommend for movies, normal TV watching? Thanks.
The X850C has better blacks and no judder, so it's better for movies and TV. If you have the room in your budget, go for that.
3
I was considering the XBR55X850C on Amazon but noticed the XBR55X800B is still available at 2/3 the price. Out use is movies and sports in a bright room. What are your thoughts on buying a previous year's model?
A good 2014 model is about the same as a good 2015 model. Since we didn't review the X800B, though, we don't know how good it is for what you're looking to do.

Does this TV output 5.1 sound from HDMI sources via the optical out? I ask since I plan to get a Sonos Playbar. I have heard all Sonys output 5.1 (if the source content is 5.1) via optical, even from devices hooked up via HDMI directly to the TV (i.e. no receiver or HDMI switcher). All devices hooked into the the HDMI ports on the TV, and optical out to the Sonos Playbar.
We haven't tested for this ourselves, but the online consensus appears to be that yes, the X850C can do 5.1 over optical.

Hello. I am considering getting the X850C in the 65" size. I then saw the 75" 1080p W850c TV right below it for a couple hundred dollars cheaper. Both TVs looked really great (obviously the x850 4k looked better), but my viewing distance is about 10-12 feet. Given those circumstances, do you think it is worth spending a little extra and getting the 65" TV with better picture, or getting the 75" 1080p Sony, which still looked great? Thank you!
The 75" W850C is a better choice, since it's the perfect size for 1080p at that distance. You won't notice the full benefit of 4k resolution at that distance, so the X850C isn't as good of a buy.
3
Why is the Sony x850c rated lower than the Samsung ju7100 in the 'Living room' category?
The x850c is less bright than the ju7100 so it can be a problem in a room with lot of windows and a lot of lights. It doesn't have a lot of reflection but it still has more than the ju7100. For both those reasons, the x850c rated lower in the 'Living Room' category.
3
Can this TV do 1080p @ 120hz @ 4:4:4? I know you've stated it can do 1080p @ 120hz, but I'd like to know if I can get that with full chroma.
Yes, it can.
2
Why is it that you consider the Motion Blur to be "Very Good" on this TV when it has 16.9 ms of Response Time. That is the worst value for that parameter that you have measured for this class of TV, yet you praised it for its Motion Blur. That doesn't make any sense at all.
The Samsung JU6500 measured a better Response Time of 16.4 ms and yet you called that motion blur "more than average" and rated it very poorly for motion blur.
Your conclusions on motion blur are not supported by the data that you present. You really should change that, as it is very confusing and misleading.
You're right that the words associated with the respective reviews aren't reflecting the TVs properly. Both TVs are currently scored the same, and are in the middle of the pack. We've updated the text for both to clarify. Thank you for pointing this inconsistency out!
2
Is there any advantage to this model being direct backlit as opposed to all the others being edge backlit? Is this the cause of the average maximum luminosity?
No, that's not the cause. Some direct-lit TVs have very bright screens.
Direct backlights tend to cause fewer black uniformity issues, so that's the advantage here.
2
I'm trying to decide between this and the LG EC9300 for mostly gaming and some cable/movie watching. How favorably does the Sony compare?
The only ways the Sony is better is for price, and for resolution (but only with real 4k material). The OLED set is very expensive, but the overall picture is better for every category, and the input lag is virtually identical.
If you're not concerned about the price and you're choosing between 55" models, get the EC9300. If you would get a larger X850C, then the bigger screen would be more worth it.
2
I cannot find the picture in picture settings that the manual says this TV has. Any help?
Press the button next to the 'Sync Menu' button while watching OTA or cable TV and PIP should work.
2
Does the Sony TV XBR-55X850C or any of the other sizes this TV comes in come with 10 Bit or 8 Bit Display Panel? Call into Sony support informed me they don't know at this time or are unwilling to disclose it. Sales person at BestBuy thinks 8 Bit. I currently have my GPU set to 12 Bit but to be honest I don't trust that it's not some trick to pretend to accept 12 Bit. I really would like to know if you can test for this or have tested and know for sure which it is. Thanks.

We still don't test for this yet but this is something we are planning to do at some point in our future reviews. For now though, 10 bit panels won't make much of a difference compared with 8 bit panels. Not without mentioning there is practically no 10-bit contents available right now. We don't know which Sony TVs have 10 bit panels but SUHD TVs from Samsung are known to have them. Thanks for your suggestion, it's always appreciated.

Update: We now have confirmed the Sony x850c uses a 10 bit panel.

With the UHDA having released the "minimum requirements" for what aa HDR TV with their approval is (I believe 1,000 nits peak brightness and 90% of the DCI color space), where does the X850C fit into this? It's HDR, but with CES it looks like only the 2016 models will meet this requirement. What I mean to ask is, will the 2016 models look THAT MUCH better for HDR that I should take advantage of the six days left to return my TV and buy a new one, or will I be fine for a couple years with the Wide Color Gamut and "Bt.2020" color space profile "HDR" of the X850C? Thanks!
The X850C covers 89.34% of the DCI P3 color space, so it doesn't meet the new color portion of the spec (which requires more than 90% coverage). It also doesn't have the ability to make very bright highlights.
Time will tell whether the 2016 models meeting the new specs really look that much better, and also whether they will fall into the same price range as the X850C. Most likely, the only noticeable difference will be the highlights, so the overall difference likely won't be so big.
2
I noticed you said that you don't yet test for 10 bit displays (a while back), but I've seen some in reviews so I'm assuming you do now? In that case, is the X850C a 10 bit display? I know it's not the most important of features but I'd still like to know.
Yes we do test for 10 bit now and ran the test on the x850c yesterday. It is indeed a 10 bit panel and although we haven't took a picture of it, the color gradient it produce is perfect with no apparent steps in color gradations. HDR content will be free of any color banding on this TV.

What are the preferred settings for motion on this TV? I feel like I've tried them all, but when watching baseball, the baseball, bat swings, or even arms waving during a talk show seem to have a flickering look to them.
The settings we list here are what we recommend for all uses. Try setting 'Clearness' to zero to remove the flickering. If you're watching interlaced content (1080i), it's possible that is what is causing the flickering, in which case there's nothing to be done.
1
Will you guys be getting the 65" or 75" model, because both are Direct-Lit rather than Edge-Lit, so this review may be misleading.
No, we only review one size. It's true that the different lighting types could mean the TVs are a bit different, but we don't expect those differences to be too big. Uniformity issues can happen on both type. For example, our E60-C3 has clouding even if it is a FALD.
1
Is it possible to improve upscaling ability through a firmware update for the X850C?
There actually has been an update which fixed the upscaling. Make sure your TV is up-to-date and you should be set.
1
Does last year's 70" version of the Sony X850B have an IPS or VA Panel? Also, would you recommend this TV?
It has a VA panel. Unfortunately, since we didn't test the X850B, we can't really say how good it is.
1
Does putting the TV in game mode reduce picture quality? I game fairly often, so if I leave it in game mode all the time, will movies or shows look worse compared to normal or customs mode?
They won't look worse, but they'll look different. Game mode disables a lot of the image processing to help drive down the input lag, and while this allows for a picture that is closer to that which is intended by the source, it's different than what most people are used to. You would likely get used to any differences you notice.
1
Please help me decide on what to buy: the x850b or x850c, based on gaming, mostly. I want best picture quality and input lag. I know the new processor helps with picture, but will the difference in input lag be noticeable?
The X850C is a better choice. The X850B has an IPS panel, which means it has weak contrast (though it does have a wider viewing angle), so picking up the X850C means you get better overall picture quality. The input lag of the X850C is mediocre, but still playable; unfortunately, since we did not review the X850B, we don't have a number for its input lag.
1
Does this TV require a sync transmitter to watch 3D? If so, can you recommend any?
No, it can display 3D on its own.
1
I have zero interest in altering motion blur/refresh rate/ etc. with my TV, as I do not like the look of the motion interpolation process, particularly in movies. Is it possible to turn these options completely OFF with the X850C? If not, is there a better choice for this?
Yes. Just disable the 'Smoothness' slider of the 'Motionflow' to get rid of the interpolation.
1
This unit is advertised as having playstation now capabilities but I can't find it anywhere did you guys notice this as well?
It's slated to come in a later update. For now, it's not available.
1
Could you please explain "1080p @ 120Hz"? I am deciding between two TVs one has the feature, the other does not. Would this affect the display of 1080p (blu ray) film content? Thank you for this amazing website!
No, it is useless for movies. It is whether the TV can accept a 1080p signal at 120 frames per seconds as an input. Currently, the only thing that can output as such are PC graphic cards, for gaming.

I've noticed that the x850c has a "grainier" picture than the JU7100. Is this a common issue? And in terms of upscaling, I've been told that Sony has the best upscaler on the market. Which brand is best to get for this year? Not really into the bells and whistles; I would just like to have better picture quality. Do you guys have a rough estimate of when you guys will be posting the x900c and Samsung JS9000 review? Thanks.
Where have you noticed this graininess? In-store display content isn't representative of what a TV can really do, so if that's where you're seeing this, it's likely not a good indication of a real phenomenon.
As for upscaling, both Sony and Samsung are very good this year, and we list our favourite TVs of 2015 (so far) here.
We'll have a review of the JS9000 up within the next couple of weeks, and we'll likely be getting to the X900C sometime in the next couple of months.

I've been going back in-forth in selecting a replacement TV for my living room. I learned a lot from you. Thanks.
The last two TVs I liked are the Samsung JU7100 and Sony X850C, in the 55-inch size.
Before, the Sony X850C had an overall score of 8.2, and now it's 7.7 with firmware v. PKG2.173.0010NAB - Android 5.0.2.
My question is, can you redo the rating with the new firmware from Sony, version PKG2.287.0010NAB? Pretty please?
Thank you very much.
The scores changed because we changed the weighting of our tests, and also added some new results to the mix. Both the X850C and the JU7100 are good TVs.
We don't expect there to be any improvement to the picture quality with the new firmware, so we won't be re-testing the X850C.

Just bought the Sony x850c, and I am unable to change the picture/display settings while using Netflix and watching movies on a USB drive. Is this common with Sony TVs? If it is possible, then please let me know how to do that. Thank you.
You should be able to adjust the settings for Netflix, USB, and other apps by doing the following. Open Netflix, and then press the 'Action Menu' button on your remote, then choose 'Picture Adjustments.' From here, you'll be able to make your changes.

Hi! So after a month the WOW effect is gone and right now I've started noticing some "defects".
4K video is awesome. Now, about playing Blu ray and MKV files. Some of them are very good. But there are a lot of movies that look terrible. In dark scenes, for example, when I come closer I can notice buzzing, flickering dots and pixels. Very strange, because I didn't notice this on my old Panasonic plasma TV, and I didn't notice it with last year's Sony w800b.
Maybe because of size? This one is 5" bigger. Or is this TV just so good that it shows you all the artifacts. It's much better when you turn off "reality creation" and increase sharpness to 45-50, and set "digital noise" to high. But in that case, the picture becomes so blurry, and you can still notice this buzzing and "dancing" of dots and pixels.
I don't know, maybe this is a common problem for any TV? Or my eyes are very sharp... :)
Thanks!
It's likely just that some of the films you are watching have grain. This is a normal artifact you see with films, and there's nothing you can do to eliminate it without having a negative impact on the picture quality. Your best bet will be to use our recommended settings for everything, including videos with grain.

Is the 65x85c same as the 65x850c? Thanks.
Yes, but for a different country.

I was told by a salesman at Fry's that Sony just upgraded its processor a few weeks ago and now it can upscale content better than other brands. Is this true and if so, does that apply to all content?
There was a firmware update recently that improved Sony's upscaling, but it's really about equal to what most Samsung and higher-end LG TVs can do.
And yes, the good upscaling applies to all content. Note that this doesn't mean there is any added detail to the image. It just means the lower-resolution content won't look too fuzzy or over-sharpened.

Hi! I find this new option on my X850C
- Update: With the new firmware update PKG2.463.0010NAB, this TV now supports 4k @ 60Hz @ 4:4:4. To enable this, go to Settings - External Inputs - HDMI Signal Format - Enhanced (new).
I turned on Enhanced for PS3, but I don't think it supports PS3. I turned back to standard. Now I'm wondering whether I did something wrong and harmed the television, because there was a warning on the screen: "Please change only if your connected device is supported"...
Now I think that I could damage the TV by doing this. Can I? :(
Thank you!
No, don't worry. You can't damage your TV by enabling that feature. It's just not going to work with unsupported devices.

Which is better for PlayStation 4, movies, and sports? The x850c or JU7500, both 55".
The JU7500. Both are good for movies, but the JU7500 has less blur and much lower input lag, so it's a better option for sports and gaming.

I've always had Sony TVs, with the exception of one Samsung, which I liked also. I'm really torn between the X850C and the JU7500. There are so many mixed reviews of which one is better.
I will be using mine as the bedroom TV I'll be sitting 3-8 feet away and front and center so viewing angles is not a concern. I'll be watching a lot of TV, so the up conversion to 4k from my DirecTV is a huge factor. I also play a lot of PS4 games. Those are the two most important factors with watching football, bball, and UFC coming in a close third.
I'm leaning toward the Sony, because I've never had any problems and I like Sony's reproduction of natural lifelike colors, but have read a lot of bad comments about the input lag on the X850C. That's the only thing really confusing me, because I do play games as much as, if not more than, I watch TV. This will be the TV I keep for quite a few years, so I want to pick the right one for me. If there is a better option <$2k for a 55", I'm open to that also. please help me make the right decision..
The Samsung JU7500 is one of the very best TVs we have seen this year. It has good picture quality for all kinds of video and it has very little input lag. For your uses, the JU7500 is definitely a better buy than the X850C, so we recommend going with it.

Thanks for your information-packed site! Will you be reviewing the upcoming Panasonic TC-60CX650U family of TVs?
We don't currently have plans to review any Panasonic TVs in 2015.

My sony 75 850c recently did an update and now supports HDR. When watching you tube 4k videos it automatically switches the pic setting to HDR and it's really washed out like the whites are too bright. The same with downloaded 4k videos on my media player. The question I have is should I go in and calibrate that pic setting with your calibrated pic settings to get the best available HDR picture. Cause the standard settings looks a lot better than the HDR setting.
The contents you are watching are probably not made for HDR while the 'HDR' picture mode is made for HDR contents. For now, HDR materials are still very scarce. Continue to use the 'Standard' picture mode if it is how it looks better to you and when you will get your hands on HDR contents then you could try to fine tune the HDR picture mode to your liking.

I am having trouble getting my external hard drive (HDD) recognized by the TV. Have tried all the USB ports, including the USB 3.0 input on the rear. All USB inputs work OK when I use a thumb drive, but not when I connect my portable hard drive. Is this a feature that is not supported on this unit (XBR65X850C)?
Sometimes, very large hard drives won't be recognized by the TV. That may be the issue here, or else your particular drive just isn't compatible. You may want to try a different hard drive (maybe a smaller one), or just stick with your thumb drive.
1
Is this a 10-bit or 8-bit panel!
Unfortunately, we currently don't have a test to determinate that yet. We plan to update our tests when 10-bit sources become more available.

Hi there. Great reviews and site you have. I noticed you gave the 850c high marks for contrast and black uniformity, but low marks for the 830c. I was under the impression these were effectively the same panel with/without 3D. I would expect nearly identical marks. It also appears other reviews (professionally or not) have given good marks for the those areas. Do you know if the panels are truly different? Is it possible you got a bad copy? - Thx, Brian
No, we didn't get a bad unit. All X830C have an IPS panel inside, which explains the poor blacks. The X850C is VA, so a better contrast, but poor viewing angle. The IPS/VA spec is rarely listed in the specs (except sometimes on LG TVs, because they are the biggest manufacturer of IPS panels). You can easily confirm this by looking that the shape of the pixels.

I love your site. I've been debating between purchasing this TV or the Samsung JS8500. This one is $500 cheaper. I like what I'm reading, except for the part about the Android OS lag. Did you guys experience any lag within the OS? Did the firmware update help any? Thanks.
No, we've never really had any issues with Android OS being too buggy to use. That said, we recently heard from someone who does find it buggy and slow, even with the latest updates.

Is your sports rating before or after the HDR update in the XBR55X850C? Thanks!
Before, but the addition of HDR would not affect our sports rating, anyway. We also don't expect HDR to be very good on this TV, as the maximum brightness isn't that high.

Noticed some banding (black screens only) on the XBR 65X850C. Maybe 3-4 lines 2-3 inches wide running most of the way from top to bottom. Is this just acceptable on these panels? Also some posterisation but as advised we got rid of most if not all of it by changing the digital noise settings to medium. Will this soften all pictures though?
We didn't noticed banding on our x850c but it isn't really rare to see some on TVs. As long as it isn't much noticeable on normal viewing it shouldn't be a problem. The 'Digital Noise reduction' setting generally make a good job at removing noise without softening the picture too much (as long as you don't set it to 'High') so it is fine to use.

Hi! I have a question. I opened Netflix on my X850C today and I start browsing. After I chose a TV show, (Marco Polo in 4K), the TV just started showing a black screen and nothing happened for about 7-10 seconds. After that, the TV just turned off by itself. I turn it back on and it started rebooting (Sony logo and circling colored dots with Android logo) After that, Netflix and everything else worked just fine. This is the first time that this TV has done something like that. Any suggestions?
Thank you!
This may have just been a one-off bug. Make sure your TV has the latest updates, and also that the Netflix app has been updated, too.
If it starts happening regularly, either perform a factory reset and see if that solves the problem, or contact Sony support and see what they say.

I'm looking at the Sony XBRX55850C and the Samsung UN55JU7100 or UN55JU7500. I have a Sonos Soundbar and Sonos Subwoofer.
I plan on connecting the TV to the soundbar via optical, which for Sony is a 5.1 output, I believe, and the Samsung is 2.1?
A salesman told me that with the Sony I can control the volume of the Sonos speakers with the TV remote, but with the Samsung I would have to use my Sonos app on my phone. Do you know if this is true?
All those TVs can output at least up to 5.1 via optical (but can also do 2.1), and you cannot control the volume over optical with any TV.
If you want to control soundbar volume with your TV remote - something all those TVs can do - you should connect via HDMI ARC instead. You will also need to enable the CEC feature. For Samsung TVs, this is called 'Anynet+'. For Sony TVs, it is called 'Bravia Sync.'

Update: One of our visitors reported that 'the Sonos Playbar is capable of learning the IR codes of any tv remote. All Samsung and Sony remotes work properly to control the Playbar volume. Playbar also only accepts optical as there is no HDMI input.'

I wish I could attach the picture to describe my issue/question better. I bought a 55" 850C. My TV display just breaks down as a wall of bricks with pictures laying on top of each other whenever I play any movie with "Cast a Tab" option. Is there any know issue?
I was looking for a 4K TV with main use of streaming movies from my Laptop using HDMI or Cast a tab. But when I use HDMI, i see flickering lines, and if I use "Cast a Tab" my TV display just breaks. Should I look into returning it for a Samsung if it works well with my laptop?
We have received a couple of questions about this. This seems to affect the X850C more than the other models. The Sony X900C and the X810C were also tested for this, and while the video was a little choppy, they didn't have that same 'wall of bricks' issue, which we reproduced on our X850C.
Your best bet here would be to transfer the videos in a different way. Sharing the videos from your PC and opening them in the video app on the TV would not have this issue. You can accomplish this with both a Samsung model or with your X850C.

Hi. I'm thinking about purchasing the 65" model, but went and saw it in-store and the colors looked very saturated and unrealistic. Is this a calibration issue? Maybe the store had it in display or vivid mode. The reds and greens were hurting my eyes.
Yes, it's definitely a calibration issue. Using our recommended settings will help you avoid that kind of look.

We are wondering if the GTX 980 is compatible with 4K @ 60 hz. We used your recommended cable through Amazon Basics and we could not get 4K @ 60 hz to work. We will get no signal when we test. Also, with 1080p @ 120 hz, we get weird feedback, small lines that pop up and disappear across the screen. We were wondering if you could give us some advice, since Sony had no clue what to say.
Update: Also we just learned that the Amazon basics HDMI cable only supports 4k @ 30 hz and we would need a faster cable. Just fyi.
Yes, that card should be compatible. Have you tried forcing the resolution in your graphics card menu? Did you enable the 'Enhanced' HDMI signal format?
As for the small lines on 1080p120, that is an issue across all of Sony's UHD TVs. Unfortunately, there does not appear to be a solution.
We have used several Amazon Basics HDMI cables and all have worked fine for transmitting 4k @ 60 hz @ chroma 4:4:4 signals, which are quite demanding, so we doubt the cable is at fault here.
1
My computer is reporting that this TV can't take a 120hz signal (or anything above 60hz). I was able to overclock my old TV to at least 65hz, so I don't think this is an issue with my graphic card. My drivers just updated, so that could be the problem, but I was wondering if there was some tricky way to get it to accept a 120hz signal from my PC. GTX 960 2gb card if it matters.
You need to create a custom resolution under the NVIDIA Control panel. That's the way we do it since the PC isn't reporting 120Hz as a supported mode.

First off, great review, very informative when deciding to buy this model. A couple of days after buying and installing this TV, we noticed a bleeding/clouding effect in the upper left corner of the screen. It was only present when that area was dark and the surrounding area has brights, not a problem with bright or very dark scenes. We took the photos from the rtings-test-materials-2014 file from a previous question here and had the TV display the black screen with white cross photo, and it was present there too. Looking at your photo from the uniformity section, ours looks similar to that (although the biggest cloud in yours is towards the lower left while ours is upper left). Are these blobs just sort of expected with LEDs, especially edge-lit ones such as this? Or would you say it sounds more like a defect?
Yes, it is normal for LED TVs to have clouding issues. As long as it doesn't bother you in everyday content, there is nothing to worry about. You can also send us a picture by email and we can weight it whether it is within normal range or not.

The YouTube app in my Sony 55XBRX850C TV shows HD options till 1080p.There is no 1440p or 2160p options available. The internet is connected through LAN and I have a 75 mbps connection. Please help!
Try with this video, which is definitely available in 2160p. It may just be that the video you were attempting to watch is not available in 2160p.
If the option still isn't available, try updating the TV to the latest firmware. That should fix the problem.

After last update, with HDR support and chroma 4:4:4, HDMI can do 18Gbps (2.0a) ?
Yes, it does support 2.0a now. We'll update that answer. Thanks!

I returned the 50in Samsung js7000 due to high clouding. The colors and brightness were magnificent and the upscaling was unreal. How does the 50in x850c compare? I know the technical numbers but I'm worried 2016 HDR content wont be bright enough. Also are reds as deep as the js7000 because I see a difference in color between the two which seems to favor the js7000. Please let me how how upscaling, red color tones, and brightness compare to the js7000.
Both TVs have similar brightness (the JS7000 is just a bit brighter) and will be able to do HDR but neither of them will be really good at it. HDR needs much better brightness to be at its best. Since the JS7000 is backlit and a little brighter, just stick with this one. Clouding might not be an issue on a new one. As for the colors and upscaling, both TVs are about equally good.

Thanks for your great website. Super helpful. However, I have a question regarding the Sony x850C. Every time I turn the TV on I have to go to the action menu and set the "Speakers" setting to "Audio System". I have to do this every time and it's kind of annoying. I use a Logitech harmony home remote to control all my devices and having to change this setting every time means I need to keep the Sony remote handy too. Is there a way to make this Speakers setting "stick" to Audio system? I thought maybe it had to do with the Arc on HDMI 4 so I changed to the HDMI 3 port. No luck. The TV keeps forcing the setting back to "TV speakers" every time. Any ideas how I could fix this.
It seems like there is a communication problem between the TV and the sound system. If you are using an optical cable, try using the HDMI ARC connection instead or vice-versa. Try a different HDMI cable too. If using ARC, make sure ‘Bravia Sync Control’ is On. It should power the sound system whenever the TV turns on. A similar option could be available on your sound system where when it is powered On it could power On the TV. You could try to do it this way instead. Lastly, if nothing works and that your sound system isn't too power hungry, you could just leave it On all the time.

I'm having issues with the aspect ratio when I use "cast to device" in windows 10 to my XBR65X810C. If a video has a resolution of 1920 x 808, it will be stretched vertically. I can't figure out the option to fix that. From my research, it seems like an issue with the TV. 1920 x 1080 videos are fine.
We tried the function today and got the same problem. The 'Wide' button (aspect ratio) on the remote wouldn't change the aspect ratio either. It seems to be a limitation of the software. Although it is kind of a pain, converting your files to 1920 x 1080 with a video editing software such as Handbrake would to be the only solution for the 'Cast to device' feature.
1
I noticed something odd about the X850C. Sometimes the remote control freezes and does not respond to any command. Once a day maybe, or twice, freezing for about 10-15 seconds. I check batteries and replace them with new ones, but it doesn't always fix the problem. Not a big deal, of course. Just wondering if you have heard about this issue. Thank you!
We have had the same issue with a few of our Sony TVs, so it seems to be a pretty widespread problem. Unfortunately, just waiting a few seconds is the only solution we have found.
For alternatives, you might also want to try connecting a different remote to your TV and trying that out, or downloading Sony's 'Video & TV SideView: Remote' app and using that to control your TV. It's available for both Android and iOS.

How is the HDR different from the HDR on the new D models. I know the HDR on the C models were added via software update whereas the D models came with it. Is the HDR on the C models considered "true" HDR.
There is no 'true' HDR and the look of it directly depend on TV features and performances. In the case of the C series vs the D series, the D series TVs have the edge because they can get brighter. The range of colors TVs can display is also a big factor for HDR but for the TVs we have reviewed so far, there is not a big difference in that domain between the two series.
1
Does the added HDR function work with the samsung 8500 4k bluray player connected to this tv, or is it only work with streaming content?
It works for both, but be sure to set in the menu the 'HDMI Signal Format' to 'Enhanced' for the HDMI input where the 4k Blu-ray player is connected, so that the TV can recognize the HDR metadata and switch to HDR mode.

Hello, for HDR 4K 4:4:4 input lag, have you disabled all effects on the settings ? It's crazy 93 ms in 4K 4:4:4 HDR.
Yes, this is with all other settings disabled. This may be fixed with a firmware update as the Sony TVs which are on Android TV 6 do not have this issue. With Android TV 5 it is not possible to activate game mode with a HDR source.

This TV has open-baffle speakers. Did you listen to them? How was that?
We're still developing our sound testing, and we'll have a proper audio review for this TV done sometime in the next month.

I am having a hard time choosing my next 65" TV and am looking for some advice. I am considering the Sony 850C, Sony 900C, and the Samsung JS8500. I mainly use the TV to watch sports, movies, and play some Xbox. I have owned many Sony TVs over the years because I have preferred the colors on Sony TVs as I feel they are more accurate. Which TV would you recommend?
Of those, we have only reviewed the X850C, so we can't properly compare those three models. The X850C is a good TV, with good contrast, uniformity, and motion handling. The input lag is only average, but you should still be able to play just fine.
0
I use my TV for about 80% gaming, 10% watching cable, and 10% streaming movies. Coming from a Sony W950B, would the Sony X850C or the Samsung JU7100 be the better upgrade?
The JU7100. Both TVs have similar picture quality overall, but the JU7100 has less input lag, which is important for gaming.

I've had the x850C model for a few days now, and I noticed there is some light bleed. But my biggest problem is that in dark scenes the brightness fluctuates up and down very quickly. Sort of like auto-brightness functions on smartphones today. I tried to 'test' this again today when the Netflix update came out. I watched Daredevil in 4K in the first episode and early minutes he is in a confession booth and the scene is generally dark. Then the brightness on the TV starts to spike up and down. I am using auto illumination LED and standard picture quality setting. Do you have any suggestions as to how I can fix this? Thank you!
It's your TV's frame dimming feature that is causing this. You should use Game mode, as that disables the dimming.

This may be a dumb question considering your rating is right in front of me, but I'm trying to decide between the Samsung JU7100 and the Sony X85C. I'm not too worried about apps. I just want to be able to stream 4k content and get the best picture I can for movies and sports. Which of those two would you recommend? I had my heart set on the Samsung, but the Sony's Quantum Dots are beginning to sway me. Thanks in advance for your time and help.
In terms of picture quality, the two are about even. You get some nice extras from the JU7100 (glossy screen, smart remote), so we recommend going for that, but either TV is a good choice.

I've had the X850c a little over a week and I've noticed stuff with the sound. For instance, I was watching Aliens and a lot of the dialogue is low--to-inaudible, while the music, background noise, and special effects almost blow out the speakers. What could be causing this? I've tried everything I could think of, to no avail.
That doesn't sound normal. You should try resetting your TV. If that doesn't work, contact Sony for assistance.

I do watch a lot of sports; no gaming. I saw both TVs yesterday and preferred the toned down pic of the X850C vs the JU7100. Your comments about how the Samsung handles motion blur better for sports concerns me. I am coming from plasma (I LOVE IT), but I'm looking for a cooler set to put in a small room. Will I be happy with sports on the 850C? Thanks.
Yes, you will still be happy with the X850C even for sports. The motion handling is above average, so don't worry about it.

How do you watch 3D on this set? I have tried through the Vudu app, but it reports the TV is not a compatible device. Do I have to buy something else to make it work?
You need compatible Active 3D glasses, and then you need to go to 'Settings' -> 'TV' -> 'Picture and Display' -> '3D Display' and set that to 'Side by side.' That should get 3D working with compatible apps and videos. We've tested it successfully with YouTube.

I'm not sure that this question applies to this TV specifically, but I was wondering what the best 4k TV is in the 70-75" range for the primary purposes of watching Blu-Ray movies and eventually UHD Blu-ray, as well as light console gaming in a home theater-like environment.
Both the UN75JU7100 and the XBR75X850C would be great for you. For primary movies, the Sony has as slight advantage, but the Samsung is better overall.
0
Due to the nature of the updates Sony has pumped out for the C series TVs, have you revisited any of your ratings after firmware updates? I know features, as well as picture quality, have improved greatly since launch. Newest firmware update should be pkg2.287, IIRC.
We updated the upscaling score following an update that fixed it. Apart from that, there isn't something that changed that affected the scoring.

I just had my Samsung plasma TV fail on me after only four years and am now trying to decide between the Sony X850C, the Vizio M60-C3, and the Samsung JU7100. I really only care about the TV's performance for sports, as I can always notice motion blurring if it exists. Any thoughts? Note that I'm sort of jaded towards Samsung now due to my current TV failing. Thanks.
All LED TVs have some blur, so you'll never find a TV completely free of it. Both the Sony X850C and the Vizio M60-C3 are good choices for sports. The M60-C3 has a bit more blur overall, but it shouldn't be noticeable with video games. If you want the absolute least, go for the Sony.

Hi, what a great site you have. I've been reading through reviews and it's clear to me you have an extreme dislike for IPS panels. But it's almost impossible to find a panel that has great blacks and great viewing angles. If viewing angle was important, which TV would you buy (in the price range of the X850C, that is)?
I thought LG's UF8500 might be an option, but I see you haven't reviewed it yet. Then again, the Sony X850B is still available, so that might be a good option as well. Unless you're of the opinion that you'd rather have a TV that has solid blacks and just deal with poor viewing angles. It's an interesting dilemma (for those that aren't ready to pay for OLED).
If you need the wide viewing angle, you're better off with an IPS TV than to deal with the reduced color saturation at an angle.
If you want a 43" or 49" TV, the Sony X830C is the best IPS option. If you want something bigger, the LG UF7600 and UF7700 are good options.

Hi! I have a few question about my x850c. There is always an onscreen notification "No signal, check the input" whenever I turn off Boxee or a PS3 system. But after I updated TV a few days ago, this notification is just gone. Right now, if there is no signal from the media player or the PS3, the screen doesn't show up this notification. It is just a blank blue screen.
Personally, I don't care too much. I just want to be sure there is nothing wrong with TV. And another question: As I understand it, House of Cards on Netflix is available in 4k now. Maybe it is. I'm not sure. How can I check the information about resolution? When I push the "Display" button on the remote, while watching House of Cards, it shows that it's a 1080p signal. Any suggestion? Thank you very much!
As long as everything else is working fine, we don't expect this indicates an issue.
It is available in 4k, but you need the UHD Netflix subscription (it's a higher tier), and you won't be able to use your PS3, as it can't output 4k. The TV's Netflix app can do 4k, though.

Hey, just wanted some clarification as to how the picture got a 7.8 when the four main scores were an 8.8 for Contrast, 9.5 for BU, 10 for Judder, and an 8.5 for 3D. Just wondering how the score is calculated because this sounds like a TV that's much better than the JS7000, JU6500, and JU7100 but it's scoring relatively close to those models.
You can find our exact formula here. In this case, it is because of the lack of local dimming.

What tools do you recommend for calibration?
It depends on how much you want to do. For free, you can use our settings, which we list here. For a bit of money, using a disc, like Disney World of Wonder, would let you delve into most of the settings yourself. For a full calibration, including color, we'd recommend a cheap colorimeter like the Calman C3. It includes calibration software, so you'd be all set to start your calibration on your own.

Are you guys going to be reviewing the Sony XBRX810C TV, or is it similar to the X850C?
We likely will, but only in a couple of months.
Update: The review is up.

I have a few questions for you regarding the 55X850C. I bought one yesterday, in part thanks to your review (thank you by the way, so far I am loving it). There are a few things I am not sure about, however, and I was hoping you could help. I apologize in advance for the length of this post, but hopefully some of this information can help others as well.
1. When watching 4k content on the likes of Netflix, Amazon, Youtube, etc is there any benefit from turning on the HDMI enhanced signal, or will that only affect things like 4k Blu-rays and PCs attached to the TV that are utilizing the correct settings to take advantage of that?
2. Along a similar line, when watching the aforementioned 4k content from streaming providers, would it benefit from setting the color space to BT 2020? Or again, is that only going to be utilized by specific content? I noticed certain dark scenes in content where the picture looks a bit red when I have it on BT 2020, even with 4k content. Would I be safe leaving the color space setting to auto?
3. When watching content on the TV that has deep shadows, I've noticed that at the very edge of the shadow, there is an area that appears to have a combination of reddish and greenish tint to it. It is right where the shadow transitions to a lighted area. I have noticed that turning the brightness (black level on this TV) up that seems to mostly get rid of it, but that is just because I am removing the depth of the shadow in the picture. I used the DVE HD Basics Blu-ray to set the brightness, so I know I have it on the right setting and don't really want to bring the value up.
The one other thing that I noticed gets rid of this is turning Live Color on to Low. It completely fixes the problem without adjusting the brightness. I am concerned about leaving that setting on, however, because I know it is post-processing the image, adding to or changing something in the color information. However, even with the setting on, I rechecked my DVE SEMPTE color bars with the blue filter and it still looks perfect, it even improved the red filter. What do you know about the Live Color feature, and is this an always off feature if I want to protect the integrity of the source?
4. I am a little confused about MotionFlow and CineMotion. I definitely don't want the soap opera effect on my content (it literally makes me feel disoriented watching it). On my old TV (a 2010 Samsung plasma), there was a feature called Film Mode that you could set to Cinema Smooth. When you turned that on, when and only when the TV received a 24p source, it would adjust the TV to 96hz, thus removing motion judder from the image without adding any soap opera effect.
Does one of these features effectively do that for the X850C? Right now I just have both features turned off. I noticed there is an option under Motionflow called True Cinema, which sounds like what I want, but at the same time on the menu for CineMotion, when you set it to medium or high it says that helps remove judder.
Thanks in advance for any help or information you can provide me, and again I apologize for the length.
1) The only time there's an advantage is when a PC is connected, as you'll get more accurate color, which is particularly helpful for keeping text looking crisp. Blu-rays and streams are encoded with chroma 4:2:0, so you won't get any advantage by setting the TV to support chroma 4:4:4 - there's no extra detail to 'unlock.'
2) You also won't benefit from the wide color gamut setting. That will just make normal content look oversaturated. Only use that setting for the upcoming content that will support it (UHD Blu-rays, for example).
3) The 'Live Color' feature didn't make a difference in our test. We'll be exploring that feature more going forward, but for now, we recommend resetting the white balance settings, as that will at least mean there will be less processing added to the image, and you should see those colored highlights disappear.
4) You need to use a combination. Set 'Motionflow' to 'True Cinema' and 'CineMotion' to 'High' and you'll remove judder without interpolating the image.

We very much dislike the soap opera effect. If you were choosing between the Sony X850C and Samsung JU7100, which would have less of this effect? How do you minimize it for that model?
You can turn it off completely on both TVs. For the Samsung JU7100, just turn off 'Auto Motion Plus'. On the Sony x850c, the feature is called Motionflow. You can set it to 'Custom' if you don't want to turn it off completely and want to have more or less of the effect.

I like to view photos using Apple TV. Does the "input lag" issue on the Sony X850C impact the process of viewing photos? Will it be slower on the Sony X850C than on the Samsung JU7100? Or is that a different issue entirely?
Also, do the photo's go through an upscaling process like videos? Is the quality of the photo image the same on a 4k TV as it is on a 1080P TV?
No. Input lag is only really an issue with fast-paced video games. You'll have no trouble with photos with the X850C.
Yes, photos can also be upscaled. The relative quality really depends on the pixel count of the photo, and also how the photo is being presented on the screen. A UHD screen has a resolution of 3840 x 2160, so to be shown fullscreen, a photo with a smaller resolution than that would be upscaled.
How good an image will look on 1080p and 4k will therefore depend on the picture. A picture with 4k resolution would look best on a 4k TV, but a 1080p photo would look best without upscaling, on a 1080p TV.

Just bought this TV and updated firmware version to PKG2.475.0010NAB, trying to use this as a PC monitor and cant find "Settings" to do the "Enhanced" on the HDMI input. I can find Action Menu>Picture Adjustments>Advanced Settings, but that's the end of the road. Looked through help and played with all the buttons on the remote cant find "Settings" to do the enhanced mode, please help. Thanks.
Use the 'Home button' on the remote, then Settings - External Inputs - HDMI Signal Format.

In your color gamut test you show the TV reaches 65% of the Rec 2020 color space. I was curious of how much of the DCI color space this TV can achieve? I know Rec. 709 is the recommended color space for normal content but to me the reds look dull and almost orange, or is that the contents fault? When I switch to BT 2020 everything is too red. The DCI color setting seems to bring out the colors (red seems to be the color that always catches my eye) and doesn't look over saturated to me, but I know it is not how it's "supposed" to look. I'm going to get my TV professionally calibrated soon, and I was wondering if it was possible to have it calibrated to the DCI color space considering how much of that gamut this TV can achieve.
For DCI, it's 89.3%, so yes, it is possible to calibrate it against DCI and get relatively close. But for normal content (aka Rec 709), it will produce oversaturated colors. You should ask your calibrator to first do it against Rec 709, and then on another mode, against DCI. That way, you will be able to change depending on the content.

HDR not supported? They just released an update that makes it look amazing, and earlier you guys commented that you wont be re testing this tv? That is like lying to the public about how much the tv has improved ever since it came out, It greatly affects picture quality. They have released so many amazing updates since you guys last tested it. Please re-test this tv with the latest firmware update. And wtf guys, why even rate how the speakers are when they all suck from all thin tvs.
Thank you for your feedback. In the past, we have updated the overall score when firmware updates affected our ratings, like when it fixed the upscaling or added 4k @ 60Hz @ 4:4:4. HDR is still not part of the overall TV score (see our score chart here). While the TV does support HDR now, our HDR test mostly work with local dimming and since it doesn't have that feature, our test wouldn't reveal anything interesting. We added a little explanation in the HDR section of the review. As for sound, we generally share your opinion on most TV sound systems but since there are exceptions (like the Sony x930c that got 8.1 for sound) and that sound is part of what you get with a TV, we want to cover as much as possible. Thanks again for your feedback!

This is a brand/model preference question. Within our budget (about $1,500), we are looking for a 55" HD or UHD TV. We are torn between Sony and Samsung. We mainly watch HD content via Dish Network and Roku. We do not game and don't watch many DVDs, although we do have a Blu-ray player. Our viewing distance is almost 10 ft. Thanks for any input.
At that size and distance, you wouldn't get much benefit from 4k resolution. Get the Samsung UN55J6300. It has very good picture quality for everything you want to watch, and it's well within your budget.

Hello, I just purchased this TV. In black scenes I have a lot of pixelation/blockiness. Sometimes even some static. This is far less noticeable in 4k content. Is this normal?
Yes, it is easier to see imperfections in dark scenes. If the TV also need to upscale the source it can get even more noticeable. Try to turn on 'Digital noise reduction'.

In the TV options under 'Picture & Display' there is a 'Dynamic Range' setting for the HDMI inputs, I was curious as to what exactly this feature does? Is there any benefit to the 'Full' option? When I switch it from 'Auto/Limited' to 'Full' the picture becomes washed out unless I reduce the black level. On a side note the Xbox One (my primary media device) has a color space option labeled 'PC RGB' that claims to be only for monitors and crushes black levels. Indeed it does unless I switch the input to the 'Full' dynamic range on the TV, then the picture looks good. Is there any correlation between these two settings?
Yes. The important thing is that the settings match. Everything should look good on 'Limited' though (most professional calibrations are made in 'Limited'). 'Full' is usually for PC monitors that uses the extra shades of gray. Since cable TV, movies and console games are made to be displayed in 'Limited', you won't get any benefit to use the 'Full' setting. Leave the TV setting to 'Auto' so it will always match the source signal.

Hey, I just want to say your site has been amazing for helping me figure out what kind of TV I need. I'm in the market for a new TV and after a lot of research I have decided to go with this Sony. My question is this: Do you think the price will drop any further towards Black Friday and the end of the year? I know it has already come down $500 from $1,300 and is a great value, but if I can hold out for a month and save a hundred or two, that would be amazing.
Based on what you've seen, do you believe this specific TV will go down any further in price? Also, in general, are there any trends I should look out for during the end of the year holidays that may benefit me?
Prices tend to drop within the couple of weeks before Black Friday, so yes, there should be a decrease soon. Apart from that, there aren't really any trends to look out for.

I currently have an Onkyo receiver that can handle 1080p 3D. I have my Xbox One, Blu-ray player, and Wii going to the receiver via HDMI, and then the receiver going to my current TV.
With this Sony 4k TV, do you recommend going straight from the Xbox to the TV, or can I still get upscaling if I go from Xbox > receiver > TV. Also, if I do get a device that handles 4k, such as a 4k Blu-ray player, will I have to upgrade the receiver as well? Thanks.
It shouldn't make a difference. The only thing that the receiver might affect is input lag, but if you don't notice anything, that's not a big deal.
And yes, if you want 4k, everything in the chain (from source to receiver to TV) will need to be capable of transferring 4k.

I assume banding is more prevalent on larger panels? It's only visible on pure black screens and there is some light bleed along the right side of the panel where the banding is, not major but somewhat noticeable when watching a 21:9 movie... Again, is this to be expected? What level of this is 'acceptable' on a $2.5k 65" TV in 2015?
I found my white, grey and red uniformity to be exceptional (blue was a little patchy), so I don't want to nit-pick as on your panel you said grey was really poor whereas mine is almost perfect... Also notice that, even though we sit pretty much straight on, the far side of the TV's blacks do appear grey, depending on which side you're sitting... Should the viewing angle really be that poor for black on this VA panel? Your calibration for this TV worked a treat, colours especially look awesome. Thanks.
Yes, the bigger the TV, the more it is prone to uniformity problems/banding. Send us a picture if you want us to comment on if it is acceptable or not on your set.
It is also normal on VA panels to notice poor blacks on the sides, but it depends on your size to distance ratio. It shouldn't be an issue if you sit straight on and far away. But if you are close, yes.

FYI: LG AG-S350 3D glasses work on my XBR75X850C panel. The Panasonic glasses for my plasma set don't pare up.
Thank you for the information!

I followed your color settings to the T, but I'm not thrilled with the colors. Oranges appear too bright and other colors are too muted. Maybe its just personal preference, but it just doesn't look good to me. I prefer the brightness at 5, which it is set at. I also changed the Adv. Color Temperature per your screenshots. Do you have any suggestions on what to try?
Try resetting the color settings back to defaults and see if they look better. The color settings we listed are only guaranteed to work for our unit. For others, they might produce incorrect results. You can also switch the color temperature to something colder than Expert1.

Does this TV support HDCP 2.2?
Yes.

Hi, is there a version of this Sony TV that has the same specs as this one, but without 3D, and that is still made by Sony? Thanks!
No. You don't need to use the 3D feature, though, so you might as well get the X810C if it's otherwise a match for what you're looking for.

Apps don't install to my Sony X850C anymore. There is an 'install pending' message on the screen, and it doesn't do anything. I try to disconnect and then reconnect everything, but it isn't working.
And the Vevo app doesn't respond. VUDU, Netflix, and Amazon Video work just fine. Any suggestions? Thanks!
We have not run into this issue ourselves. Have you tried installing from your PC? Try downloading the Vevo app from here. If that doesn't work, you should contact Sony for assistance in correcting the issue.

My question is should i keep my sony 55 inch 850c or take it back and get the 65 inch Samsung ju6400. I play alot of xbox one on my tv and a lot of fast first person shooters and looking at the spec on the Sony it looks like not a great gaming tv. I can take it back and get a bigger better TV for gaming at about the same price. Should I keep it or should it go?
We haven't had a confirmation yet but we expect the 65" JU6400 to have a different panel (VA) than the 55" we reviewed (IPS) with better image quality. With its lower input lag, it would be better than the x850c for fast action games like first person shooters. The x850c has other advantages like the capability to control the backlight to clear motion some more (at the cost of overall picture brightness) and the fact that its input lag stay relatively playable while using Motionflow (around 70 ms, something most TV can't do). For the kind of games you play though, a faster input lag is what matter the most so the JU6400 would be best.

Can the Sony X850C play Blu-ray movies at 60 fps (frames per second) when the new Samsung UBD-K8500 4k Blu-ray player comes out?
Yes, it can.

Hi there, I have a few questions: Context: Use: I want to buy a computer monitor tv that I can play specifically 3d first person games and then watch few 3d movies, tv and old movies converted to 4k 3d ideally. For gaming i don't play anything too competitive, no online battles just single player mode so I can deal with a little input lag but not too much. Between input lag or immersion i am definitely on the immersion side. I can deal with a little lag but ideally i want the best of both. I will be gaming all 3d in 1080 max as no graphics card can do 3d in 4k anyways. And the odd time i game or using my desktop it will be in 4k 2d. Questions: 1. What would you recommend Sony 65x850c or Samsung JU7500 x65? -In almost every area the Samsung is superior. The input lag is half, it has inbuilt 2d-3d conversion, comes with glasses, has a better 3d rating, you said it has no visible cross talk, can do everything the 850c can do and more except 120hz 1080p. Seeing as that I want to do 3d gaming this seems like a huge thing, as i would love 60 hz per eye as at 1080 is where all my 3d gaming will be done. What do you recommend? Any chance Samsung will firmware upgrade this? 2. Im guessing 850c due to 120 hz is better at 3d, 60 hz per eye at 1080p. Are you aware if this works with Nvidia 3d vision 2.0? Any knowledge on G-sync etc? 3. If I was to convert the 2d content on my pc and send it to tv that should be fine right? Then the tv could take my 3d signal and upscale it to 4k? Thanks so much, and wow, I love your site! And yes, i know someone already mentioned it, but please list the HDMI input types on TVs. No one else is doing this and for something so damn important it's mind numbing why no one is.
Thank you for the HDMI type suggestion. We will add more information in our reviews in 2016 and we will see if we can add this particular info. Here are the answers to your questions. 1. The Samsung JU7500 is the better choice for 3D since even the Sony x850c can't do 3D while it receive a 120Hz signal. A firmware update isn't likely to change that. Still, for regular 2D gaming, only the Sony can display a 120Hz.

2. Like just mentioned, 3D won't work with an input signal of 120Hz.

3. You are correct. This will work.

The picture calibration seems to change when I switch between apps or HDMI inputs. How do I apply settings to all modes?
Unfortunately, there is no option to apply picture settings to all inputs. You will need to go to each one and apply the settings there individually.

I recently purchased an x830C for my bedroom. At first I thought 49" would be way more than I could stand, however, after a few weeks I am thinking of going larger to a 55". I think I will stay with Sony and, based on your reviews, was thinking of going with an x810c as it's only a little more expensive than what I already spent. My question is, do you think it would be worth it to spend a little more and get the x850c? Just wondering, since that model will (or probably has already) receive an update to be able to display at least some HDR whereas neither of the other models will. Thanks in advance for your advice!
The x850c is already HDR compatible but it isn't particularly good at it since it is edge lit. The x810c has slightly better contrast, less motion blur and better screen uniformity. You would enjoy those features better than being able to watch non-optimal HDR content.

Thank you for the nice informations on this website.
I own a KD55X8505C (German PAL model) with a Motionflow frequency of 800Hz. As the US model (Motionflow 960Hz) actually works with a native refresh rate of 120Hz, I presume my TV has a native refresh rate of 100Hz. So I have three questions.
1. 24p material works undistorted with 120Hz, but how does it work with 100Hz? The German website Shows, that this model supports True Cinema. How can the TV achieve this without speedup the frame rate to 25Hz?
2. Same question, but with a 60p signal from a PC/console on 100Hz instead of 120Hz.
3. Your review metions 120Hz Support for PCs. If I buy a PC with HDMI 1.4b output (Mine has 1.4a and doesn't show an option for 120Hz. Please correct me, if the minimum requirement is not 1.4b.) with the intention of 120Hz-gaming, will it be possible like with the US model? Thank you very much.
Both 24 hz and 60 hz work fine on 100 hz European TVs, as the European HD spec specifically requires that the panels can adjust their refresh rates to accommodate these frequencies.
As for whether 120 hz gaming might work, there's a good chance that it will. In your graphics card settings, try creating a custom resolution of 1080p @ 120 hz and see if it works on your TV. You can verify whether you're getting genuine 1080p120 by connecting a PC to your TV and visiting this website.

I recently bought a 65" X850C and noticed some clouding when going to a black screen. It looks very similar to your black uniformity picture in the review, which surprised me, because you mention excellent black uniformity, but it appears to show obvious patches/clouds, and especially in the left lower quadrant.
I'm coming from an old Panasonic plasma, so I could be nitpicking. Is this just something I should expect with LED TVs, or is this a defect?
Every LED TV has this kind of problem to some degree, and the model we reviewed has very little of it in comparison with other models we've looked at. Plasma doesn't have this issue, so yes, you have been spoiled for a bit. If your TV looks really similar to ours, hold onto it, as you're unlikely to find something better if you exchange for a new model

1) Could you test whether enabling/disabling 4:4:4 affects input lag on Sony? At least for Samsung 2015 TVs, only the PC Mode has 4:4:4 and also higher input lag than the Game mode. Is 4:4:4 processing inherently slower? I think you should update your input lag chart to reflect whether 4:4:4 is used or not to make the comparison fair, because for PC Gaming 4:4:4 improves image quality. I guess PS4/Xbox One lack 4:4:4 support. 2) Sony source says "10bit driving of an 8 bit panel (8bit + Hi FRC)" for all their 2015 4K TVs. I guess in practice this is almost as good as a native 10bit panel?
1) Chroma 4:4:4, on Sony TVs, is enabled by default on the 'Game' picture mode. Our 1080p input lag measurements is then valid for 4:4:4. We agree that the 'PC Monitor' section has to be improved with more details and resolutions. We are working on it. 2) As for bit depth, an 8 bit panel with good processing can display a very similar gradient patter than on a 10 bit panel. In our tests, when that happen, we identify the TV as being 10 bit. We will soon add a score to our gradient test so it can be compared between TVs a little bit easier.
We are not taking any more questions for this product because we no longer have it in our lab.
