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.
Excellent all-round performance. Perfect blacks results in infinite contrast ratio. Picture quality is excellent. Motion blur is non-existent. Picture remains accurate when viewed at an angle. Input lag is slightly higher than ideal. Some temporary image retention after static images.
Terrific for watching movies in a dark room. Picture quality and dark scene performance are excellent due to perfect blacks.
Excellent for TV shows in a bright room. Picture quality is unbeatable, and looks great from any angle. Unfortunately the whole screen can't get bright to deal with glare. WebOS smart platform works well.
Excels for watching sports. Picture quality is great and remains accurate at an angle. Negligible motion blur which is great. The uniformity is great, and results in almost no dirty screen effect.
Great for gamers. Picture quality can't be beaten, and motion performance is excellent. Unfortunately the input lag is only slightly better than average, so may be an issue for the most hardcore gamers. Some temporary image retention may be visible after static content.
Exceptional HDR performance for movies. Supports HDR10 and Dolby Vision. Perfect blacks results in excellent dark scene performance. Highlights can get quite bright, and supports a wide color gamut for vivid colors.
HDR picture quality is exceptional, with support for wide color gamut. Unfortunately highlights can't get as bright as some other high end TVs and high HDR input lag may be an issue for some people.
Great choice for PC monitor. Picture remains accurate when viewed at an angle. Supports chroma subsampling and a wide range of resolutions for clear text. Motion handling is excellent. Unfortunately there is some temporary image retention.
We tested the 55" (OLED55C6P). For the most part, we expect our review to be valid for the 65" (OLED65C6P).
If someone comes across a different type of panel or if their LG OLED 55C6P doesn't correspond to our review, let us know and we will update the review. Note that some tests such as the gray uniformity may vary between individual units.
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.
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.
The video is for reference only, since there is no need for a local dimming feature on OLED TVs.
The LG C6 OLED TV have an average SDR peak brightness and is on par with the LG E6. The ABL (Automatic Brightness Limiter) also affect the brightness of highlights bigger than 25%, making anything beyond that point darker than the smaller highlight.
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.
After playing static material, temporary image retention is still an issue on this TV.
The LG C6 OLED TV is able to display a 10 bit gradient very efficiently without any major banding or color shade issues. Some little imperfections can be seen here and there in the darker shades of color, but this is not really a problem and should not be visible when watching normal content.
The white balance calibration is performed with the inbuilt 2 and 20 point system. It works well to finely adjust the white balance.
The colors space calibration is a bit less responsive than the white balance one, but it is still possible to bring down the Color dE a bit more.
You can see our recommended settings here.
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.
Just like the other 2016 OLED TVs, the C6 has a large color volume. It is able to cover almost all of the P3 color volume and produce saturated colors even at low luminance.
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.
Movies played from a Blu-ray player or built-in streaming apps appear smooth. Some judder may be noticed when watching movies over a cable box or home theater PC. Most people don't notice judder so this is not an issue.
The C6P is able to interpolate 30 fps or 60 fps content up to the native refresh rate of 120 Hz. To do this and enable the soap opera effect, set 'Trumotion' to 'User'. For a 30fps source increase 'De-Judder' and for a 60fps source increase 'De-Blur'. Note that this may introduce visible artifacts.
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.
Although this TV has a 120Hz panel, like other LG TVs it can't accept a 120Hz signal. To activate chroma subsampling, change the input icon to 'PC'. This allows for clear text on all backgrounds. For higher bandwidth signals such as 4k @ 60Hz @ 4:4:4, activate 'HDMI ULTRA HD Deep Color' on the HDMI port you are using in the 'General' settings.
Good performance. Frequency response is good at lower volumes. At higher volumes though, pumping and compression will be present. Additionally, low-end cutoff and maximum loudness are decent, for a TV.
Poor harmonic distortion performance. The overall amount of harmonic distortion at 75dB and 85dB are decent. However, at maximum volume, there is significant rise in distortion, especially above 1KHz. Aliasing was also audible with our test signal under maximum load.
As with the other 2016 LG TVs, the C6P has the newest version of the WebOS smart platform. It is extremely stable and smooth, and works very well. The smart remote with included pointer allows for very fast navigation, and all of the menus and features are very easy to use. The interface is intuitive which is great. The TV comes with popular apps such as Netflix, Hulu and Amazon Video and provides access to the LG Content Store for a wide range of other apps. It is possible to play photos or videos from a USB drive plugged into the side of the TV.
Includes the same smart remote as other high-end LG TVs such as the B6 and UH8500. Works well to browse WebOS with the pointer.
