LG's C series is probably one of the most recognizable and most frequently chosen OLED TV lines in the world. And it's no wonder. For years it has occupied the ideal spot in the middle of the manufacturer's lineup, being clearly more advanced than the entry-level B series while not costing as much as the G-series flagships. In practice that means we get most of the key features, a brighter panel, and very good gaming capabilities without having to opt for the priciest OLED in the lineup. In 2026 that role is taken over by the LG OLED C6. But are the differences from the cheaper B6 big enough this time to actually justify paying extra for it? Let's find out.

Overall rating
The LG C6 is a very successful evolution of one of the most popular OLEDs on the market. The TV itself hasn't changed dramatically compared with last year's C5; the look is very similar, webOS offers comparable features, and gamers again get pretty much everything you'd expect from a modern TV. It's hard to fault that, since the C5 was already a very complete device in that regard. The most important change took place where there was actually room for improvement: the panel itself. The new WOLED panel is noticeably brighter, and roughly 1500 nits in HDR makes it increasingly hard to treat the C6 as just a "mid-range OLED." HDR movies look very impressive, black stays perfect, colors are very good, and the new processor (the same one found in the flagship G6) handles upscaling and lower-quality content very well. Add to that a seriously strong set of features for gamers. 165 Hz from a PC, VRR, G-Sync and very low input lag mean you can just as well hook up a console as a powerful PC. During the day the C6 also performs better than previous generations, though of course in a very bright living room you'll still find brighter TVs on the market. And that's probably exactly why we like the C series most: its versatility. The C6 doesn't try to be the best TV in every possible category, but it hardly performs poorly in any of them. It's suitable for movies, sports, gaming, regular TV and everyday streaming. If its price starts to fall after launch as it did with previous generations, it could be one of the most interesting OLEDs to buy in 2026.

In terms of appearance the C6 series has hardly changed in recent years. And it's hard to complain, because the design simply works. It's a very well-built OLED with exceptionally slim bezels surrounded by a metal trim. Depending on the exact model designation its color can vary slightly, but the construction itself remains very similar. The screen is very thin, although the rear housing protrudes noticeably at the bottom, so the TV can't be hung completely flush on the wall. Even so the whole set still looks very elegant. The back is made from LG's characteristic plastic whose texture somewhat resembles stone or marble. Here too the shade can vary slightly depending on the version and region.
Across all C6 variants you get a central stand that does its job well and looks very neat. It's made partly of metal and partly of plastic, but visually it's hard to fault. The only thing to complain about is the cable management. The C6 practically has no sensible covers or channels to hide cables properly. After connecting several devices the cables can therefore be quite visible from the side, which somewhat spoils the otherwise very tidy look of the whole design.

If we talk about black levels, there isn't much to discuss. The LG C6 uses an OLED panel, so each pixel can be completely turned off. The result is exactly what we'd expect: perfect black, very high contrast, and no halo or glow around bright elements. You can see this clearly in night scenes, where single lamps, text, or other bright points appear against a very dark background. The C6 handles them without any problems and doesn't have the limitations typical of Mini LED TVs with local dimming. Interestingly, in this respect it doesn't matter whether we're talking about this version of the C6 or the more expensive variant with a Tandem OLED panel. In terms of black alone, both TVs perform practically identically. Differences between them need to be sought mainly in brightness and color.
NOTE: In the helicopter scene from the film Sicario 2 we noticed graininess and flickering in the darkest parts of the image. It looks like a software bug that LG should fix with an update. In the Tandem OLED version the effect is even more visible, and we observed similar behavior in the flagship LG G6 as well.

The HDR effect on the LG C6 is really very good. LG Display's new WOLED panel primarily brought a significant increase in brightness. In our unit we measured around 1,500 nits and, importantly, the TV can show similar values in many normal movie scenes. That gives HDR the proper impact. Bright highlights, lamps, or sunlight can be really strong, and most HDR movies simply look very impressive. Of course it's still an OLED, so brightness drops in scenes with a lot of white. The fifth scene of The Meg illustrates this well, where the C6 reached about 600-700 nits. That's still a very good result, but it also shows the new panel hasn't removed all the limitations typical of OLEDs.
When it comes to color, there is also little to complain about. The C6 covers about 99% of the DCI-P3 gamut and roughly 75% of BT.2020. In practice the colors are very saturated and, importantly, stable regardless of the scene. That's worth emphasizing, because not every TV behaves the same in this respect. In some RGB Mini LED models color saturation can depend more strongly on image brightness. Today a wider color gamut is mainly offered by QD-OLED TVs and new SQD models with a new generation of quantum dots. However, the C6 still performs very strongly here and is able to generate appropriately saturated colors in most movie scenes.

Scene from the movie “Pan” (about 2800 nits)
Scene from the movie “Billy Lynn” (about 1100 nits)
In HDR movies the C6 simply performs very well. With material mastered to around 1000 nits, like Billy Lynn, there's little to complain about, because the TV already has a bright enough panel to show that material without major losses. It also handles much tougher scenes well. In Pan the brightness of the material can far exceed the panel's capabilities, but the C6 has no major problem with that. Tone mapping works well enough that the image remains readable and doesn't lose detail in the brightest parts. The only thing that caught our eye was a slightly boosted brightness. As a result, in some scenes the C6 shows a bit more detail than it should compared with the reference image. It's not a big flaw, but you can notice it in a direct comparison.
HDR luminance chart:
This comparison clearly shows that the C6’s factory tone mapping for HDR10 is fairly aggressive. The TV tries to extract as much brightness from the image as possible, but that comes at the expense of some detail in the brightest areas. On snow or bright backgrounds, some details simply start to merge. Dolby Vision handles this noticeably better. The image is a bit calmer, but we recover a lot of information in the highlights, so the snow’s texture, the background, and subtle transitions between the brightest tones are more visible. The difference isn’t huge, but in such demanding scenes Dolby Vision simply delivers a clearer image.

Right out of the box the LG C6 is pretty well set up, especially if you choose Filmmaker mode. In SDR material the white balance is decent, although as brightness increases it starts to lack a bit of red. The picture becomes a little cooler as a result, but it’s not such a big difference that it stands out during normal viewing. More happens in the brightness response itself. Gamma is a bit low and instead of holding at 2.4 it sits closer to 2.1–2.2 over much of the range. In practice the C6 slightly brightens midtones. Shadows are therefore more readable, but the image loses some depth compared with how it should look in a dark room. In HDR the situation is a bit more interesting. The start of the grayscale looks very good, but from about 20–30% brightness the white balance starts to drift more and more. As brightness rises there’s more red and a noticeable lack of blue. In the brightest highlights the difference is already significant and also affects reproduction of some colors. The EOTF curve itself is handled fairly well over most of the range. The C6 only has a tendency to slightly brighten the image, which we also saw during our film comparisons. The largest deviation appears around the brightest highlights, where the TV begins to adapt the signal to the panel’s capabilities. So the out-of-the-box Filmmaker mode in HDR isn’t perfect, but overall it performs well. The biggest room for improvement is the white balance, especially at high brightness.
9.1/10
LG TVs have been very receptive to calibration for years, and the C6 is no exception. After adjustment the white balance was set almost perfectly, and most color errors dropped to values below 3, often even around 2. In practice this means very accurate color reproduction in both SDR and HDR. An interesting detail appeared only with the HDR brightness characteristic. On a classic EOTF chart everything looks nearly ideal, and at first glance it would be hard to find fault. Only when we measured the TV’s behavior using filters based on actual movie scenes did it become clear that the C6 has a slight tendency to artificially boost image brightness.
It’s not a huge difference and many people may even see it as a positive, because HDR looks a bit more impressive this way. From the standpoint of fidelity to the source material this isn’t ideal — some scenes are simply a touch brighter than the filmmaker intended. Interestingly, this is somewhat unusual for LG. In previous generations, the brand’s TVs typically stuck very closely to the reference tone curve after calibration. With the C6 we’re still very close to the standard, but that subtle boost in brightness is indeed noticeable in films and series.
7/10
The LG C6 handles tonal transitions very well. In most movie scenes it was hard to notice any obvious posterization issues. Both in the dark parts of the image and in bright gradients the colors remain relatively smooth and do not break up into visible bands. That's good news, because WOLED panels haven't always been perfect in this regard. With the C6 it's clearly better, and during normal viewing this aspect of the image shouldn't draw attention.
Note: One downside is the dithering visible in near-black areas. Up close you can notice subtle flicker and grain in the darkest parts of the image. It's not as pronounced as with the Tandem OLED panel, but it still occurs, so we decided to dock the C6 a few points in this category.
8.5/10
Smooth transition function
Image without overscan on the SD signal
The LG C6 has taken a really big step forward here. The TV uses the same processor found in the flagship G6, and in terms of image processing the two models are very similar. That’s a big plus, because in this area LG’s processor this year performs excellently. The "Smooth Gradation" feature works especially well. With heavily compressed material it can effectively hide ugly tonal transitions and artifacts that often appear, for example, in lower-quality streaming. It’s best to leave it set to "Low." Then the improvement is clear, and the TV doesn’t yet start blurring fine details. Higher levels smooth the image more, but can already remove some of the natural texture of objects on the screen. The upscaling itself also performs very well. Lower-resolution content is sharpened properly, edges look clean, and the processor quite effectively rebuilds fine details. In this regard the C6 is already very close to LG’s best TVs, and the differences compared with the G6 are small.

Maximum refresh rate of the panel: 165Hz
Film motion smoothing option: Yes
Blur reduction option: Yes
BFI function 60Hz: Yes, 60Hz (image flickers)
Brightness drop with BFI: 49%
The LG C6 features a panel with a maximum refresh rate of 165 Hz, which is great news especially for gamers using a powerful PC. For movies, sports, or consoles we'll of course use up to 120 Hz, but even then it's hard to fault the motion clarity. As you'd expect from an OLED, the panel's response time is almost instantaneous. Moving objects therefore don't leave the characteristic smears you still see on LCD TVs. This is particularly noticeable in sports and fast-paced games, where the picture remains very clean even during dynamic motion.
For movies and TV, LG also provides the TruMotion motion-smoothing system. In the user settings you'll find two separate sliders. De-Judder is mainly for low-frame-rate content, that is primarily 24 fps films and series. It can slightly reduce the characteristic judder, or be set higher if you want a much smoother image. De-Blur is useful for higher-frame-rate material, mainly sports broadcasts and 50/60 fps television.

We also have an OLED Motion feature here, a solution that uses BFI, inserting black frames to improve motion clarity. However, on the C6 we don't see much point in using it. It causes noticeable flicker, can significantly reduce brightness, and doesn't improve motion enough to make up for those drawbacks. It's definitely better to stick with the panel's standard operation and, if needed, use TruMotion.
10/10
LG has focused heavily on gamers for years, and the C6 really lacks nothing important. The TV supports 4K at 120 Hz from consoles, and when connected to a PC it can run up to 165 Hz. It also offers VRR from 40 to 165 Hz, ALLM, and properly working HGiG. A big plus is Dolby Vision support for games, so the Xbox Series X can use that format without sacrificing game mode. The package is rounded out by a Game Bar that lets you quickly check key signal parameters and change settings without leaving the game. In terms of features, the C6 is one of those TVs that’s really hard to find fault with. Whether you play on PlayStation, Xbox, or PC, practically everything you could expect from a modern gaming TV is available here.
9.9/10
In terms of input lag, the C6 performs as a good gaming TV should. At 120 Hz we measured about 5 ms, so controller input is practically instantaneous. At 60 Hz it rises to around 14 ms, which is still good. Slightly higher input lag appears in Dolby Vision. At 120 Hz we get about 14 ms, and at 60 Hz about 22 ms. In practice, if you're playing normally on an Xbox, it's unlikely to be something that will really bother you.

The C6 also performs very well when connected to a computer. The TV correctly supports 4:4:4 chroma, so text, icons and other small UI elements are displayed sharply. That means you can use it not only for gaming but also for regular work in Windows without major issues. One limitation is the four-subpixel matrix layout. If you sit very close to the screen, you may notice slight colored fringing along the edges of some fonts. However, this is not particularly bothersome and is practically invisible from a normal viewing distance. The C6 also has a lot to offer PC gamers. From a PC you can take full advantage of the 165 Hz refresh rate, plus there’s G-Sync, VRR and a very low input lag of around 5 ms at maximum refresh. Combined with the OLED’s ultra-fast response time, this delivers a very smooth, clean image with no visible smearing. So if someone plans to hook a powerful PC to the C6, the TV can easily serve as a large gaming monitor and also works quite well for everyday productivity.
7.4/10
Brightness drop at an angle of 45 degrees: 33%
Viewing angles on the LG C6 are very good and are actually among the best you can find in TVs today. That’s largely thanks to the OLED panel itself. Even when you sit noticeably to the side, the picture still maintains good contrast and the colors don’t lose much of their saturation. Because of that, the C6 is very well suited to a larger living room where not everyone sits directly in front of the screen. Only at very extreme angles can you notice slight changes in color, but during normal viewing it’s hard to regard that as any kind of problem. In this respect, really only Samsung Display's QD-OLED panels perform better.
6.6/10
Panel finish: Glare
Reflection suppression: Decent
Black levels during daytime: Very Good
The LG C6 has a glossy panel that handles direct reflections quite well, but it doesn't eliminate them completely. If there's a large window or a bright lamp opposite the TV, their reflections will still be visible. On the other hand, the screen preserves blacks well in a lit room, and even during the day the picture doesn't become gray or washed out. Additionally, the C6 is fairly bright in SDR. With typical content we measured about 470 nits, so in most living rooms it should handle daytime viewing without major issues. Brightness only starts to drop significantly when a large portion of the screen is occupied by white. This is still one of the typical characteristics of OLEDs, and you can notice it with very bright content, such as winter sports. Overall the C6 performs well in a normally lit living room. However, if the TV will sit opposite huge windows and have to battle strong sunlight for most of the day, a bright Mini LED will still be the better choice.

System: WebOS
System performance: Very good
Regardless of which C6 variant you end up with, the feature set is the same. At the heart of the TV is, of course, webOS, the system LG has been developing for many years. It runs fast, is well optimized and, above all, provides access to practically all popular apps. Netflix, Disney+, Prime Video, YouTube, Max and other streaming services - in that respect there are few gaps. The system itself also offers plenty of extra features. There’s AirPlay, easy screen mirroring from your smartphone, control of smart home devices and the ability to personalize the home screen. LG has been expanding webOS for several generations and sometimes the number of tabs and recommendations can be a bit overwhelming, especially with background ads, but once you get used to it the system is convenient and, most importantly, works smoothly.
The C6 also handles being used like a regular TV very well, not just as a screen for Netflix. Over-the-air TV reception, the program guide and channel switching all work smoothly and there’s little to complain about. LG still offers the ability to record shows to USB, so in terms of classic features the set is really well equipped. There are basically only two things missing. The first is PiP, the ability to display two video sources at once. The second is a backlight on the remote, which would be useful for evening viewing. Other than that the C6 has pretty much everything you can expect from a modern TV.
When buying the C6 it’s worth paying attention to the remote, because LG has created a bit of a mix-up here. During our tests we had, among others, the C64 variant, found in large retail chains. That package included the new, much smaller Magic Remote Slim. It has fewer buttons and looks far more modern, but it still keeps two of LG’s most distinctive remote features - the scroll wheel and pointer control by moving the remote. The C6E we tested came with the older, larger Magic Remote. It works essentially the same, but has a classic numeric keypad and many more physical buttons. It looks less modern, but some people, especially those used to classic remotes, may find it more comfortable. So there’s no single answer to which remote is better. The new one is smaller, simpler and decidedly more contemporary, while the older one gives faster access to more functions without navigating through menus. It’s good to know that depending on the C6 model code the box may contain one or the other variant.

During our tests the TV handled practically all of the most popular video formats we put on a USB flash drive without any problems. There were no issues with high bitrates, subtitles, or more demanding files, so it's hard to find fault with it in that respect. The only exception was material with a DTS audio track. This is not surprising, since the TV simply does not support that codec. Besides, the TV’s media player is good enough that most users will be fine without installing third-party apps or hooking up an external player.

In terms of sound, the C6 has hardly changed compared with last year’s C5. We still get a 2.2 system with a total output of 40 W, which is a somewhat more solid foundation than the simple 2.0 20 W setups in many TVs. In practice the sound is quite good. Dialogues are clear, the sound isn’t overly flat, and the extra speakers provide a bit more bass than many basic TVs. Of course it still won’t replace a good soundbar, let alone a full home theater, but it’s more than enough for everyday TV viewing.
There is a small step back in the settings, though. LG removed some of the preset sound modes this year, which makes it a bit harder to tailor the sound to your preferences than with the previous generation. For that reason our rating is slightly lower, even though the speakers’ capabilities remain virtually unchanged. On the plus side, the TV supports Dolby Atmos, currently the most popular surround format for films and streaming. It still lacks DTS support, which may matter mainly to people using their own movie libraries on discs or files.
