This tv has been discontinued.
It was replaced by the LG C7

Type : OLED
Resolution : 4k
Refresh Rate : 120 Hz

The LG C6 is a 4k OLED TV with excellent picture quality. The dark scene performance can't be beat, and the picture remains accurate even when viewed at a wide angle. Motion handling is excellent, with no motion blur following moving objects. As with other OLED TVs it's not perfect though as the screen can't get very bright to deal with glare and it suffers from temporary image retention after displaying static images.

LG C6 Design Picture
Curved : Yes

The design is almost exactly the same as the LG B6, but with a curved screen. It looks great, and stands out in any room. The clear plastic stand and the thinness of the screen are nice touches to the otherwise minimal look. Unlike the higher model E6, the speakers are built into the body of the TV.

Stand

The stand looks the same as the B6, and is made of transparent plastic. It has a small footprint but feels stable.

Footprint of the 55" TV stand: 11.3" x 27.0"

Back

Picture Quality

As with the other LG OLED TVs, the picture quality is excellent. With an infinite contrast ratio and a perfect black uniformity, this makes a perfect TV for watching movies in a dark room. Peak brightness is not as high as the best LED TVs, but it is still very good and a big improvement over the last year's OLED TVs.  The very good gray uniformity, wide viewing angle and the very good upscaling performance make the C6P one of the best TVs for watching sport with a lot of friends. Finally, the color space coverage is very good and will provide some of the best HDR performance out there.

Like with the LG E6P, the C6P is much better than 2015 OLED TVs, but unfortunately ABL (Automatic Brightness Limiter) is still present on the C6 and it limits the maximum brightness allowed on a full white screen. This is why, when you look at the results, the bigger the white surface gets, the dimmer it is. This may be distracting as the brightness changes depending on the scene.

Like the other LG OLED TVs, the screen brightness of a static image tends to diminish after some time. This might just be a screen protection or an energy saving feature. Once again, it is only when a static image is left on screen for a long time and should not have any impact on normal video content.

The gray uniformity of the C6 is very good, and better than any LCD TV. Dirty screen effect is not really an issue but still it is not perfect. On our test picture, you can notice some large vertical bands that are warmer than the rest of the screen.

The LG C6P has a wide color gamut, which can cover almost all of the P3 color space. This is about the same as the LG B6 and E6. Setting the color gamut to 'Wide' provides the most colors, 'Normal' is suitable for SDR content and 'Extended' is somewhere in between.

The LG C6 present image retention, like all the other OLED TVs. The image retention is a bit less intense than on LG LED TVs like the UH8500, but it lasts much longer. The brighter the static image is, more noticeable is going to be the retention. You can clearly see on the left side, where the white background was, it is now much darker than on the rest of the picture. The image retention can be pretty annoying for people that play a lot of video games or may use this TV as a PC monitor, since the static image will get retain for a bit more time than any LED TV. But once again, note that we did not notice any permanent burn-in on this OLED TV.

Input lag is better than average, and should be fine for most people. When the TV detects a HDR signal it switches to a HDR picture mode, which has fairly high input lag. For the best result with SDR content, change the picture mode to 'Game'. The input lag performance is the same as the E6, and slightly different to the B6. A video of the input lag differences can be seen here.

Update 11/08/2016: Some owners have started a petition to LG to address these issues. This can be found here.

Update 12/02/2016: With the newest firmware update (04.30.19) there has been the addition of a HDR gaming mode. In this mode the HDR input lag is lower, and should be fine for HDR gaming. Note that although the TV accepts a 4k @ 60Hz @ 4:4:4 + HDR signal, it can't accurately display the chroma subsampling in any HDR mode, even with the 'PC' icon selected. The HDR chroma subsampling looks the same as the B6, visible here .

Update 01/24/2017: The input lag has been updated for the newest firmware (04.30.95). The results are almost identical.

Bottom right: LG UH8500 (55UH8500).  Unlike our other photographs, this picture wasn't taken under a controlled environment, so do not draw conclusions from it.

Although the LG OLEDs are priced above the competition, they offer superior picture quality especially in darker scenes. The 2016 models all offer similar performance, which makes the C6 a great choice as one of the more affordable models. Keep this in mind when viewing our recommendations below.

Samsung KS8000
49" 55" 60" 65"

The Samsung KS8000 is an excellent all-round choice if you don't quite have the budget for an OLED. The whole screen gets brighter, which gives it an advantage in a bright room. The picture quality is still very good, but degrades when viewed at an angle. Although it has more motion blur than the LG C6, it has a different type of motion which some people prefer.

LG B6
55" 65"

The LG B6 is almost the same TV, but without a curved screen. Otherwise it offers almost identical performance and is available for the same price. It doesn't have the 3D feature of the LG C6 and has slightly different input lag depending on the source (see our review). If you don't care about the 3D then go with the shape (curved or flat) which you prefer.

Vizio P Series 2016
50" 55" 65" 75"

The VIzio P Series 2016 provides excellent dark scene performance for an LCD, but can't get the pure blacks of an OLED. It does offer a dedicated low input lag port for gamers, which is great. The worse gray uniformity results in some dirty screen effect. The picture quality degrades when viewed at an angle, but the HDR performance is the best an LCD TV can offer. If you are in a darker room and can't afford an OLED then the Vizio P Series 2016 is the best choice.

LG UH8500
55" 60" 65" 75"

The LG UH8500 is a great all-round TV for those with wide seating. It can't get very deep blacks and so is better suited to a bright room, but offers very good HDR performance and picture quality. If you don't have the budget for an OLED or are looking for a larger TV in a living room then it is a great choice.

Does image retention appear to have improved in any way from the 2015 models? Thanks.
We hope to add a test for image retention in the coming months, but at the moment we don't have a good way to compare this. It is still an issue on the 2016 models.

Do you have suggestions on the picture settings for HDR blu ray content?
When playing HDR content the TV will change to a HDR picture mode. We recommend using 'HDR Standard' as it allows the most settings to be adjusted. Keep the 'OLED Light' on max. We use the 'Warm2' color temperature as it's closest to our calibration goal, but you can adjust this if you prefer a cooler image.

Recently I saw the C6 side by side with the B6. The B6 seemed to have a glossier finish in the store display. I thought that maybe due to the heavy lighting in the store it was just more reflective than the curve? Do you know if these two models have the same screen? Thanks, and love your reviews.
They are the same finish, however the curve does have a significant impact on direct reflections. You can see a comparison of the two reflections here for the C6 and here for the B6.

is the image retention permanent? I play games for a while where a certain graphic is a constant on the screen (health, ammo, etc.) How do you get a video game rating of 8.9 when HDR input lag is so bad? Will I really notice a 67.5ms lag on these type of TVs?

No it isn't and there is an operation on the TV ('Clear Panel Noise') which works to remove any persistent retention.

There is both the 'Video Games' score for SDR gaming and 'HDR Gaming' score for HDR gaming. The 'HDR Gaming' score is lower due to the increased input lag in a HDR picture mode. This HDR input lag is an issue for gamers.

Hello, you said for HDR content use HDR Standard Mode. What about for Dolby Vision? Will it be Movie Dark (User)? Also, what other changes can we do for these two Modes and does it work for every input? Thanks.
Yes, 'Dolby Vision Dark' is the equivalent to 'HDR Standard' and yes it is good for all inputs. When in this mode, not all the picture settings are available, but for those that are, you can copy the same settings that we use from the settings page.

Could you start testing Dolby Atmos ARC passthrough? I was disappointed this TV doesn't pass Atmos.
We have a limited throughput of tests to add, and unfortunately Atmos is low on our priority list.

Between the 55" C6 and B6, which would you recommend for the best gaming performance?
They are both very similar, but the LG B6 is better because of its lower input lag for 4K @ 60 Hz.

Why does the C6 have a better rating than the more expensive E6? In particular, the color shift on the C6 appears to be much better than the E6. Is there a logical reason for this? Leaving aside cost differences, is this the prime reason to recommend C6 over the E6?
The C6 and E6 are functionally identical except for the curve of the C6 and the sound bar of the E6. A difference in our scores of 0.2 or less isn't very significant. OLED panels themselves vary a bit from unit to unit, so the differences we measured between the B6, C6 and E6 are the same as if we had measured three E6 units for example. We recommend the C6 because it is cheaper.
We are not taking any more questions for this product because we no longer have it in our lab.
