The C series from LG is probably one of the most recognisable and most commonly chosen OLED TV ranges in the world. And it's not hard to see why. For years it has occupied the perfect middle ground in the manufacturer's line-up, being clearly more advanced than the entry-level B series, yet not costing as much as the flagship G models. In practice you get most of the key features, a brighter panel and very good gaming capabilities, without having to opt for the most expensive OLED in the range. In 2026 that role is taken over by the LG OLED C6. But are the differences compared with the cheaper B6 large enough this time to make it worth paying extra? We find out.

Overall rating
LG C6 is a very successful evolution of one of the most popular OLEDs on the market. The TV itself hasn't changed radically compared with last year's C5, the look is very similar, webOS offers comparable features, and gamers once again get pretty much everything you can expect from a modern television. You can't really complain, since the C5 was already a very complete piece of kit in that regard. The most important change came where there was still room for improvement, namely the panel itself. The new WOLED panel is noticeably brighter and about 1500 nits in HDR makes the C6 increasingly hard to dismiss as just a 'mid-range OLED'. HDR movies look very impressive, black remains perfect, colours are very good, and the new processor, the same one found in the flagship G6, handles upscaling and lower-quality material very well. On top of that there's a really strong set of features for gamers. 165 Hz on 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, although 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. It's suitable for cinema, sport, gaming, regular TV and everyday streaming. If its price falls after launch as it has 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 for several years, and it's hard to complain because the design simply works. It's a very well-made OLED with exceptionally slim bezels, framed by a metal trim. Depending on the specific model designation, its colour may vary slightly, but the overall construction remains much the same. The screen itself is very thin, although the rear casing protrudes noticeably at the bottom, so the TV can't be hung perfectly flush against the wall. Even so, the whole unit still looks very elegant. The back is made from LG's characteristic plastic, the texture of which is a little reminiscent of stone or marble. The shade may also vary slightly depending on the version and distribution.
Regardless of the C6 variant we get a central stand that does its job well and looks very tidy. It's made partly of metal and partly of plastic, but visually there is little to criticise. The only element we can fault is the cable management. On the C6 there are practically no effective covers or channels that would let you hide the cables properly. After connecting several devices the cables can be quite visible from the side, which somewhat mars the otherwise very stylish look of the whole design.

When it comes to black, there really isn't much to say. The LG C6 uses an OLED panel, so each pixel can be completely switched off. The result is exactly what you'd expect: perfect blacks, very high contrast and no halo around bright elements. This is particularly apparent in night scenes, where single lamps, captions or other bright points appear against a very dark background. The C6 handles them without issue and doesn't suffer from the limitations typical of Mini LED TVs with local dimming. Interestingly, in this respect it makes no difference whether we're talking about this C6 or the more expensive Tandem OLED variant. In terms of black levels both TVs perform practically identically. The differences between them are primarily to be found in brightness and colour.
NOTE: In the helicopter scene from the film Sicario 2 we noticed graininess and flickering in the darkest parts of the image. This looks like a software bug that LG should fix with an update. The effect is even more noticeable on the Tandem OLED version, and we observed similar behaviour on the flagship LG G6.

The HDR performance of the LG C6 is really very good. LG Display's new WOLED panel has primarily brought a considerable increase in brightness. In our unit we measured around 1,500 nits and, importantly, the TV can deliver similar values in many typical film scenes. That gives the HDR the necessary impact. Bright highlights, lamps and sunlight can be really intense, and most HDR films simply look very impressive. Of course it's still an OLED, so brightness falls in scenes with a lot of white. This is well illustrated by the fifth scene in the film The Meg, where the C6 reached around 600 to 700 nits. That's still a very good result, but it also shows that the new panel hasn't shed all the limitations typical of OLEDs.
When it comes to colours, 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 colours are very saturated and, importantly, stable across different scenes. This is worth emphasising, because not every TV behaves the same in this respect. In some RGB Mini LED models colour saturation can depend more strongly on image brightness. A wider colour palette is nowadays offered mainly 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 produce suitably saturated colours in most film scenes.

Scene from the movie “Pan” (about 2800 nits)
Scene from the movie “Billy Lynn” (about 1100 nits)
In HDR films the C6 simply performs very well. With material prepared to around 1,000 nits, like Billy Lynn, it's hard to have major complaints, because the TV already has a sufficiently bright panel to show such material without significant loss. It also copes well with much more demanding scenes. In Panie the brightness of the material can far exceed the capabilities of the panel itself, but the C6 has no major problem with that. Tone mapping works well enough that the image remains readable and does not lose detail in the brightest parts. The only thing that caught our eye was a slight boost in brightness. Because of that, in some scenes the C6 shows a bit more detail than it should compared with the reference image. It's not a big fault, but you can notice it in a direct comparison.
HDR luminance chart:
In this comparison it is clear that the factory tone mapping in HDR10 on the C6 is quite aggressive. The TV tries to extract as much brightness from the picture as possible, but this is at the expense of some detail in the brightest areas. On snow or a bright background some details simply start to wash out. Dolby Vision handles this noticeably better. The image is a bit more restrained, but we recover a lot of information in the whites, so the texture of the snow, the background and the subtle transitions between the brightest tones are more visible. The difference is not 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 colour errors dropped to values below 3, often even around 2. In practice this means very accurate colour reproduction, both in SDR and HDR. An interesting quirk only appeared with the luminance response in HDR. On a standard EOTF chart everything looks almost ideal and at first glance it would be hard to criticise. Only when we measured the TV's behaviour with filters based on actual film scenes did it become clear that the C6 has a slight tendency to artificially boost image brightness.
This is not a huge difference and many people may even view it positively, because HDR consequently looks a little more striking. From the perspective of fidelity to the source material this is not ideal, however, as some scenes are simply a touch brighter than the filmmaker intended. Interestingly, this is rather unusual for LG. In previous generations the brand's TVs typically stuck very closely to the reference picture characteristic after calibration. With the C6 we are still very close to the standard, but this subtle brightness boost is indeed noticeable in films and TV series.
7/10
The LG C6 handles tonal transitions very well. In most film scenes it was hard to spot any obvious posterisation issues. Both in the dark parts of the image and in bright transitions the colours remain relatively smooth and do not break up into visible banding. That’s good news, because WOLED panels have not always been perfect in this respect. On the C6 it is noticeably better, and during normal viewing this aspect of the picture should not draw attention.
Note: One drawback is the dithering visible around blacks. At close viewing distances you can notice slight flickering and graininess in the darkest parts of the image. It is not as pronounced as in the version with a Tandem OLED panel, but it still occurs, so in this category we decided to take a few points off the C6.

Smooth transition function
Image without overscan on the SD signal
Here the LG C6 has taken a real step forward. 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 considerable plus, because in this area LG's processor this year performs excellently. The "Smooth Gradation" function in particular works very well. With heavily compressed material it can effectively hide ugly banding and artefacts that often appear, for example, in lower-quality streaming. It's best to leave it set to "Low". That way the improvement is clear and the TV does not yet start blurring fine details. Higher settings smooth the image more aggressively but can already remove some of the natural texture of objects on the screen. Upscaling itself also performs very well. Lower-resolution content is sharpened correctly, edges look clean, and the processor quite effectively reconstructs fine details. In this respect 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

Brightness drop with BFI: 49%
LG C6 received a panel with a maximum refresh rate of 165 Hz, which is great news above all for gamers using a powerful PC. In films, sport or on consoles we will of course make use of up to 120 Hz, but even then it is hard to fault the motion clarity. As befits an OLED, the panel's response time is almost instantaneous. Moving objects therefore do not leave the characteristic smearing or trails that we can still see on LCD televisions. This is especially noticeable in sport and fast-paced games, where the picture remains very clean even during dynamic movement.
For films and television LG has also prepared the TruMotion motion smoothing system. In the user settings you will find two separate sliders. De-Judder primarily addresses low frame-rate content, that is mainly films and TV series at 24 fps. You can use it to slightly reduce the characteristic judder or set a higher value if you want a very smooth image. De-Blur is useful for higher frame-rate material, chiefly sports broadcasts and 50/60 fps television.

You can also find the OLED Motion feature here, a solution that works on the principle of BFI, inserting black frames to improve motion clarity. On the C6, however, we don’t see much point in using it. It produces noticeable flicker, can significantly reduce brightness, and does not deliver enough motion improvement to offset those drawbacks. It’s definitely better to stick with the panel’s standard operation and, if necessary, use TruMotion.
10/10
LG has long focused heavily on gamers, 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 at up to 165 Hz. There is also VRR from 40 to 165 Hz, ALLM and a properly working HGiG. A big plus is support for Dolby Vision in games, so the Xbox Series X can use that format without giving up Game Mode. It's rounded off by a Game Bar, from which you can quickly check key signal parameters and change settings without leaving the game. In terms of features, the C6 is therefore one of those TVs that is really hard to fault. Whether you're gaming on a PlayStation, an Xbox or a PC, practically everything you could expect from a modern gaming TV is available here.
9.9/10
When it comes to input lag, the C6 performs as a good gaming TV should. At 120 Hz we measured around 5 ms, so controller response is virtually instantaneous. At 60 Hz it increases to about 14 ms, but that's still a good result. Latency is slightly higher with Dolby Vision. At 120 Hz it's around 14 ms, and at 60 Hz about 22 ms. In practice, if you're playing normally on an Xbox, this is unlikely to be something that will actually bother you.

The C6 also performs very well when connected to a PC. The TV correctly supports 4:4:4 chroma subsampling, so text, icons and other small UI elements are displayed sharply. That means it can be used without any major issues not only for gaming but also for regular work on Windows. A limitation remains the panel's four-subpixel layout. If you sit very close to the screen, you may notice slight coloured fringes on the edges of some fonts. This is not especially bothersome and from a normal viewing distance it practically disappears. The C6 also has a lot to offer PC gamers. With a PC you can use the full 165 Hz, and there is G-Sync, VRR and very low input lag, which at the maximum refresh rate is around 5 ms. Combined with the OLED’s lightning-fast response time, this delivers a very smooth, clean image with no visible smearing. So if someone plans to connect a powerful PC to the C6, the TV can comfortably serve as a large gaming monitor, and it also performs quite well for everyday work.
7.4/10
Brightness drop at an angle of 45 degrees: 33%
Viewing angles on the LG C6 are excellent and effectively among the best you can currently find in TVs. This is largely thanks to the OLED panel itself. Even when you sit noticeably to the side, the image still maintains good contrast and the colours do not lose much of their saturation. That makes the C6 very well suited to a larger living room where not everyone sits directly in front of the screen. Only at very wide angles can you notice slight colour shifts, but during normal viewing it is hard to regard this as any real problem. In this respect, only Samsung Display's QD-OLED panels actually 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 does not eliminate them completely. If there is a large window or a strong lamp opposite the television, 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 does not become grey or washed out. In addition, the C6 is fairly bright in SDR. With typical content we measured around 470 nits, so in most living rooms it should cope during the day without much trouble. Brightness only begins to fall more noticeably when a large portion of the screen is occupied by white. This is still one of the typical characteristics of OLEDs and it can already be noticed with very bright content, such as winter sports. Overall the C6 will perform well in a normally lit living room. However, if the television is going to sit opposite huge windows and fight 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 come across, the set of features remains the same. The heart of the television is, of course, webOS, the system LG has been developing for many years. It runs quickly, is well optimised and, above all, provides access to practically all popular apps. Netflix, Disney+, Prime Video, YouTube, Max and other streaming services — in this respect it is hard to find major gaps. The system itself also offers a lot of extra options. There is AirPlay, easy screen casting from a smartphone, control of smart home devices and the ability to personalise the home screen. LG has been significantly expanding webOS for several generations and at times the number of available tabs or recommendations can be a little overwhelming (especially with ads in the background), but once you get used to it the system is convenient and, most importantly, works smoothly.
The C6 also handles being used as a normal television very well, not just as a screen for Netflix. Terrestrial TV support, the programme guide and channel switching all work smoothly and there is little to complain about. LG still offers the ability to record programmes to USB, so in terms of traditional features the equipment is really comprehensive. In fact we only miss two things here. The first is PiP, the ability to display two video sources at the same time. The second is a backlight for the remote, which would be particularly useful for evening viewing. Apart from that, the C6 has pretty much everything you can expect from a modern television.
When buying the C6 it is worth paying attention to the remote, because LG has caused a bit of confusion here. During our tests we had, among others, the C64 variant, commonly found in large retail chains. The set included the new, much smaller Magic Remote Slim. It has fewer buttons and looks decidedly more modern, but still retains two of LG remotes' most distinctive features: the scroll wheel and cursor control by moving the remote. The C6E we tested, on the other hand, was equipped with the older, larger version of the 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 traditional remotes — may find it more convenient. So there is no single answer as to which remote is better. The new one is smaller, simpler and decidedly more contemporary; the older one offers faster access to a larger number of functions without having to navigate through menus. It's worth knowing that depending on the C6 marking, you may find one or the other variant in the box.

During our tests the television handled virtually all the most popular video formats we copied onto a USB stick with no problems. There were no issues with high bitrates, subtitles or more demanding files, so in that respect there is little to complain about. The only exception was material with a DTS audio track. That is no surprise, however, because the television simply does not support that codec. Aside from that, the player is good enough that most users can get by without installing external apps or connecting an additional player.

In terms of sound, the C6 has hardly changed compared with last year’s C5. It still uses a 2.2-channel system with a total output of 40 W, so a somewhat more solid foundation than many TVs that rely on simple 2.0-channel setups with 20 W. In practice the sound is quite good. Dialogue is clear, the tonality is not overly flat, and the extra speakers deliver a bit more bass than many basic TVs. Of course it still won’t replace a good soundbar, let alone a home cinema, but it is perfectly adequate for everyday TV viewing. There is a small step back in the settings. LG removed some of the preset sound modes this year, which makes it a little harder to tailor the sound to your preferences than with the previous generation. For that reason our score is slightly lower, although the speakers’ actual capabilities remain virtually unchanged. A plus is support for Dolby Atmos, currently the most popular surround-sound format for films and streaming. Support for DTS is still missing, which may matter mainly to people using their own film libraries on discs or as digital files.
