The Sony X900C 4k LED TV is very thin and has good color accuracy at an angle. However, the blacks are poor and not uniform, which means it is not a great choice in a dark room.

The top half of the Sony X900C is extremely thin (only 0.5 cm / 0.20"). The bottom half is thicker, but still relatively thin compared to other TVs. It will look great in any room.

The 55" version (XBR-55X900C) almost didn't fit on our testing table. It is the widest stand that we have tested this year so far. If you don't have a wide table, and you don't want to mount the TV on your wall, you might consider buying a third party stand (VESA compatible) like this one to replace the original TV stand. The stand on the 65" can be placed in the middle, solving this issue.

Picture Quality

This Sony TV isn't really great for watching movies. While it has really good motion control and 3D, it has poor contrast ratio and non-uniform blacks, so the dark movie scenes won't look great.

If you plan on mainly watching movies, the Sony X850C is a better TV for this usage.

It has an IPS panel, so the blacks aren't good. It also suffers from IPS glow, which makes the blacks 'move' when you change position.

Smart OS : Android

The Android TV OS is good overall, and it is constantly improving.

It loses a few points, though, because the included smart remote isn't very good (at least not as good as Samsung's or LG's), so browsing apps or the web is a bit harder.

Was just able to see the XBR75X910C at a local retailer. Wow, big difference between the 65X900C and the 75X910C. The new screen design looks stunning. Hope you guys will be able to review it soon.
We don't currently have any plans to review it, but we'll reconsider if enough people request it.

Does the light bleeding get worse on the x900c as the set gets older.
No. It shouldn't change unless the TV is moved around.
5
Since you tested the 55", would you expect the 65" (& 75" with the x910c) to have the same, a better, or a worse viewing angle?
We expect it would be about the same.
5
The X850C seems near identical but with better blacks and uniformity. Is there anything that justifies the $1,000 premium of the X900C?
I do prefer the stand, as it's better suited for a sound bar. Any idea if these are interchangeable between models?
The higher price is mostly because of how thin the X900C is, so while it looks nice aesthetically, there's no real justification in terms of picture quality. The stands aren't swappable, unfortunately.

Does this TV do 1080p @ 120hz on all inputs?
Yes.

First of all thank you so much, many of us have tremendous appreciation for this site. Perhaps you could have a pay-pal donation link as I bet a lot of us would like to throw you at least 10 bucks for all the info! My question is: I have the 65x900c and will be using it for 4K gaming at 60hz, with 4,4,4 chroma and 8 bit color. I currently use your recommended settings, but what might I change for gaming? I think I would at least like to make the colors pop a bit more, even if sacrificing a small amount of accuracy. Thanks!
Thank you for the kind words! We don't have any donation system as it is but if you want to help, we get a commission on anything you buy using our amazon links. There is a few things you can do to get more vivid colors without sacrificing your accuracy. First, make sure you are under the 'Game' picture mode. Then start by increasing the backlight (a brighter screen can often make a good difference). To saturate the colors some more you can use a colder 'Color temperature' setting. The 'Color' slider under the 'Color' menu can also saturate the colors some more. Finally, there is the 'Color space' value that can be changed but it may bring too much saturation and look odd on some content. Let us know what settings you end up with.

If this TV can now do 4k@60hz with 4:4:4 chroma thanks to the latest firmware update, would it be possible to get the graph for PC Monitor and Review updated to reflect this?
Yes. We'll be updating it shortly.

I am trying to decide between the 75" Sony X910C and X850C & the Samsung JU7100. We enjoy watching movies, watching golf events & a little football, and using Apple TV to show photos in the family room. We never play video games. We use Verizon FIOS, if that makes a difference as well. Which TV would you favor?
Get the Samsung JU7100. It has good blacks, which will make movies look good. It also has very little blurring on fast movement, and not too many darker patches on the screen, which can be distracting while watching sports. Overall, a great choice for what you want to do.

Hello, what TV that is less than 41" wide and has true HDR can I get. I saw TVs with marketing of HDR but they don't specify whether it's HD10 or Dolby. I would like a 4K, HDR with the width not wider than 41" since wider will not fit in my entertaining center. Samsung advertises HDR in their UHD, but I've read that true HDR has to be their SUHD line. Also, it needs to be HDR10 for my Xbox. Having HDR Dolby and HDR10 would be ideal, but at least HDR10. The Sony and LG have true HDR but not smaller than 55" help please.
There is not a lot of TVs with HDR (HDR10 or DV HDR) in the size that you are looking for. HDR is a premium feature and usually only offer in the bigger size. The only TV that would fit your requirement that we have reviewed yet would be the Samsung KU6300 in the 40" or 43", but the HDR performance is really not the best out there unfortunately.

Have you heard of the major defect in the Sony 900c model? Amazon reviews were saying serial numbers below 5002237 were bad and Best Buy had a recall. Some other sources are reporting the problem still persists. I am REALLY interested in the 900c but worried I would have a similar problem. Any thoughts or insights into this issue? Thanks.
We have heard about some light bleeding issues on this TV and the edges of our unit does bleed a little but it is not terrible and we wouldn't exchange it for that. Our serial number fall below 5002237 too. We would say buy it. You can always exchange it if any problem.

First of all, thank you very much for your service. You mentioned in previous answers that the Sony X900C cannot do HDR, but the Samsung JS9000 and JS8500 can. In BestBuy, Sony advertises that all models, X850C and higher can do HDR. Are they lying?
They aren't lying. When we reviewed the x900c, HDR wasn't yet supported. It has now been implemented with a firmware update. We just added a note in the review about this. Thank you very much for pointing that out.

I see an option in Picture settings to set the Dynamic range to [Full/Limited/Auto] for All HDMI inputs and Screen Mirroring. Would it be a good advice to always keep these options to "Full" for all inputs? Does this affect the TV in ways like power consumption, input lag, dropping frames, etc.? Also, same question for keeping all the options in HDMI Signal Format to always be "Enhanced"
No this will not effect the television in both input lag or power consumption. The goal is to match the source, so set it to 'Auto' unless there is a problem with the detection. As for the HDMI signal format, you only need to use 'Enhanced' for 4k content that requires a higher bandwidth. Turning that feature on won't negatively affect the picture though.

From what I have seen the light bleed issue on this set has been fixed by Sony. It was due to a factory defect. Those who have tested it after the fact give it very high grades. The up-scaling in particular gets kudos. Any Comments?
In general, all Sony TVs are good at upscaling low quality video source. If you are planning to use your TV in a dark room and the black uniformity in important to you, there are better TV out there. But if you can past that, the Sony X900C is good TV that look great.

With its wider color gamut and current brightness levels tested, how does HDR on this to look compared to similar TV's in this price range? I only ask because you can find this TV brand new for under $1500
That's a great price for the X900C. Generally for HDR content, most people watch from in-front in a dark room. The issue with HDR content on the X900C is that it has a IPS panel, with no local dimming. This means that in a dark room, blacks appear gray. This results in an average implementation of HDR and highlights stand out less than other TVs with darker blacks. For a similar price, the Vizio P is a better pick for raw picture quality. Note that the 55" Vizio P Series 2016 also has a IPS panel and so the same drawbacks, but the remaining sizes in the series are a good choice. It is expected to receive an update for HDR10 support within the next week.

Hello, I bought the X900C 55", I was originally going to get the 810C but the 900C just had more going on for the money despite the IPS panel vs the 810's VA panel. HDR support wide color gamut, decent sound. My question is I am a gamer and when I game I cannot seem to get 1440P @60hz to work? It is always @30hz? I can get 1080 @60hz and 4K @60hz no problem but 1440p will not get 60hz? I use a GTX 980ti and I would like to game @1440 until I get a GTX 1080ti later this year. Thanks, Eric
We have tested our X900C and it does accept the 1440p @ 60Hz resolution with our GTX 960. The one thing that could cause your problem is maybe your HDMI cable. Just be sure to use a high speed HDMI cable like this one.

Hey, Yalls reviews are absolutely fantastic. Thank you so much! Does this TV (x900c) have true HDR. You said it came in a update, but is it the real and full fledged feature. I'm looking to get the Xbox One S and want to make sure this supports HDR for external hardware. Thanks so much, Blake
The Sony X900C supports a HDR10 input, but has average HDR performance. It does support a wide color gamut so colors will look vivid, but can't get very bright to exaggerate highlights and doesn't have any local dimming features. Basically, it will work with the Xbox One S and there will be some picture improvements but is not the best TV for HDR gaming.

I am really confused as to which TV to buy. Bestbuy has a sale of $979 on a 2015 Sony model XBR55X900C. But as I read reviews, I'm a little concerned whether this is a good TV or not. Why is the Sony X900B more expensive?
The X900C is a good TV, if you have a well lit room with a lot of seating at a wide angle. But, if you have a dark room, because it has an IPS panel, it will no necessary be the best choice.

The reason why the Sony X900B is more expensive is that it was the top of the line TV in 2014 and have more features like a local dimming option and a special design with a full set of front facing speaker that the X900C don't have.

I had a Samsung 8550, but after two bad panels in four months I decided to have my retailer junk the unit out and start over.
After much debate between the Samsung JS8500 and the Sony X900C, I decided to go with the Sony. I really do like the TV so far. It's been about two weeks, but I'm seeing noticeable "light bleed" from both bottom corners and even up the sides of the panel.
It isn't as terrible as some customers have been posting about online, but when you're talking about a TV in this price range, there should be ZERO issues. Should I exchange my 900C for a new one and hope to get a better set, or should I swap it out for a Samsung JS8500?
If it's bad enough that it's disturbing you while you watch, you should get a different unit. You'd have better luck avoiding those issues with the JS8500, but if you like the X900C, try getting a new one of those and see if it's better.

In an answer above, you commented "not too many darker patches on the screen, which can be distracting while watching sports". Is that an issue on the Sony X850C? The colors on a Sony look more "natural" to me. It's important that the green on a golf course looks true, and that photographs are displayed with accurate color. The colors on a Samsung look brighter but not as true. Is that fair?
Our 'Gray Uniformity' test is the indicator for this. The x850c scored a 5.8 in that department. As an example, the JU7100 that we were talking about in the other answer, only got a 6.5 and that is not the best but higher than most LED TVs we reviewed. So 5.8 on the x850c is average (that does vary a little between same model TVs). Since our calibration is the same for all TVs, we end up with very similar colors on both Sony and Samsung TVs.

I'm trying to decide on a (55in) TV mainly for PC gaming, but also the occasional movie. I think the flexibility to go between 1080p at 120hz or 4k at 60hz depending on content gives this a slight edge over the Samsung JU7100. However, according to the specs provided on Sony's website, this TV's HDMI inputs are only "Up to 3Gbps: 4:2:0 (8 bit)". Is this a typo on their website? Or am I better off going with another product if all of my content is going to be provided via an HDMI (or displayport) port?
The information on the website is incomplete. From our tests, we can confirm the x900c support 4:4:4. If 1080p @ 120Hz is important to you, than the x900c will be the TV to get instead of the JU7100 that can't do it.

I heard about the Sony X900C's light bleed issue too. So I am worrying about it as well. I know the X900C comes with A new X1 engine.
1. Does the X850C have the same light bleed issue?
2. Does Sony X850C have the same engine too?
3. How does the new X1 Engine work? Is it really good?
4. The 900C is $500 more than the X850C. I would like to go with the Samsung JS8500, not the X900C. Any advice for choosing between the JS8500 and the X850C?
1. No.
2. Yes, it does.
3. The X1's upscaling does work well, but it's not head and shoulders above mid-range and high-end TVs from other brands.
4. The JS8500 is a bit better overall, as it has less blur on fast movement, and also support for HDR. If you want those features, get the JS8500. If not, the Sony X850C will work well for you, as it has great overall picture and performance, for cheaper.
0
Is there a way to connect this tv to a Bluetooth speaker (beats pill+)?
We haven't tested that specific bluetooth speaker so we can't say for sure. All we can say is that even if the X900C has bluetooth support, we found that Sony TVs have limited compatibility with headphones, if that could be of any indication.

Which one do you recommend out of XBR 65X 900c, 950b or 930c. I love watching movies specially 3D on this 65" TV screen. I want to see the best blacks, contrast and color.
Go with the X930C. Both the X900C and the X950B have IPS panels, which results in a much worse contrast ratio and blacks that appear gray. Although the X930C is more pricey, the picture quality is much better and the active 3D is very good.
We are not taking any more questions for this product because we no longer have it in our lab.
