LG's C series is probably one of the most recognisable and most popular OLED TV ranges in the world. And it's easy to see why. For years it has occupied the perfect 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 flagship G models. In practice you get most of the key features, a brighter panel and very good gaming capabilities, without needing to reach for the most expensive OLED in the lineup. In 2026 that role is filled by the LG OLED C6. But are the differences from the cheaper B6 this time big enough to really be worth paying extra for? We check it out.

Overall rating
The LG C6 is a very successful evolution of one of the market’s most popular OLEDs. The TV itself hasn’t changed drastically 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. You can’t really complain, since the C5 was already a very complete device in that respect. The most important change is where there was room for improvement: the panel itself. The new WOLED panel is noticeably brighter, and roughly 1500 nits in HDR makes it increasingly hard to see the C6 as just a ‘mid-range’ OLED. HDR movies look very impressive, blacks remain perfect, colours are very good, and the new processor, the same one found in the flagship G6, handles upscaling and lower-quality sources very well. There’s also a really strong offering for gamers. 165 Hz from a PC, VRR, G-Sync and very low input lag mean you can just as easily 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 it’s probably that versatility we like most about the C series. The C6 doesn’t try to be the best TV in every possible category, but it doesn’t really fall short in any. It’s suitable for movies, sport, 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 changed very little over the past few years. That’s not surprising, because this design simply works. It’s a very well-made OLED with exceptionally slim bezels and a metal trim. Depending on the exact model designation, the colour may differ slightly, but the overall construction remains much the same. The panel itself is very thin, although the rear housing protrudes noticeably at the bottom, so the TV can’t be hung completely flush to the wall. Even so, it still looks very elegant. The rear panel is made from LG’s distinctive plastic, with a texture 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 neat. It’s made partly of metal and partly of plastic, but visually there’s little to complain about. The only thing to pick on is cable management. The C6 really lacks useful covers or channels to hide cables. With several devices connected, cables can be quite visible from the side, which detracts a bit from the otherwise very tidy look of the whole build.

If it’s about black levels, there’s not much to discuss. The LG C6 uses an OLED panel, so each pixel can be completely turned off. The result is what you’d expect: perfect black, very high contrast and no haloing 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 trouble and there are none of the limitations typical of Mini LED TVs with local dimming. Interestingly, in this respect it doesn’t matter whether we’re talking about this C6 or the more expensive Tandem OLED variant. When it comes to black levels themselves, both TVs perform practically identically. The differences between them are mainly in brightness and colours.
NOTE: In the helicopter scene from 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. On the Tandem OLED version the issue is even more noticeable, 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 mainly brought a significant increase in brightness. In our unit we measured around 1500 nits and, importantly, the TV can show similar values in many normal movie scenes as well. That gives HDR real punch. Bright highlights, lamps and sunlight can be genuinely intense, and most HDR movies simply look very impressive. Of course it’s still an OLED, so brightness falls in scenes with a lot of white. The fifth scene from the movie The Meg illustrates this well, where the C6 reached around 600 to 700 nits. That’s still a very good result, but it also shows the new panel hasn’t shed all the limitations typical of OLEDs.
When it comes to colours, it’s also hard to raise major objections. The C6 covers about 99% of the DCI-P3 gamut and roughly 75% of BT.2020. In practice colours are very saturated and, importantly, stable regardless of the scene. That’s 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 gamut today 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 produce suitably saturated colours in most movie 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 mastered to around 1,000 nits, like Billy Lynn, it’s hard to find major faults, because the TV already has a bright enough panel to show that material without significant loss. It also handles much more demanding scenes well. In "Panie" the material’s brightness can far exceed the panel’s capabilities, but the C6 doesn’t have much trouble with that. Its tone mapping works well enough that the picture remains readable and doesn’t lose detail in the brightest parts. The only thing we noticed 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 spot it in a direct comparison.
HDR luminance chart:
In this comparison it's clear that the factory tone mapping for HDR10 on the C6 is fairly aggressive. The TV tries to pull as much brightness out of the picture 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 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 you can better see the structure of the snow, the background and the subtle transitions between the brightest shades. The difference isn't huge, but in such demanding scenes Dolby Vision simply delivers a clearer picture.

Right out of the box the LG C6 is quite well set up, especially if you choose the Filmmaker mode. In SDR material the white balance is decent, although as brightness increases there is a slight lack of red. The image becomes a bit cooler, but not enough for it to be very noticeable during normal viewing. More is happening in the brightness characteristic. Gamma is a little low and instead of holding at 2.4, for a large part of the range it sits closer to 2.1–2.2. 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 darkened room.
In HDR the situation is a bit more interesting. The start of the greyscale looks very good, but from about 20–30% brightness the white balance starts to drift increasingly. As brightness rises there is more red and a noticeable lack of blue. In the brightest sections the difference is already significant and also affects the reproduction of some colours. The EOTF curve itself is followed quite well through most of the range. The C6 only tends to slightly brighten the image, which we also saw in our film comparisons. The largest deviation appears around the brightest parts, where the TV starts adapting the signal to the panel's capabilities.
The factory Filmmaker setting in HDR is therefore not perfect, but overall performs well. The biggest area for improvement is the white balance, especially at high brightness.
9.1/10
LG TVs have long responded very well to calibration, and the C6 is no exception. After adjustments we managed to set the white balance practically perfectly, and most colour errors fell below 3, often down to around 2. In practice this means very accurate colour reproduction in both SDR and HDR. An interesting detail only appeared with the HDR brightness response. On a classic EOTF chart everything looks almost perfect and at first glance it would be hard to find fault. Only when we measured the TV’s behaviour using filters based on real film 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 viewers may even see it as a positive, because HDR looks a bit more striking as a result. From the point of view of fidelity to the source material, however, it’s not ideal — 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 held very closely to the reference picture curve after calibration. The C6 is still very close to the standard, but that subtle brightness 'boost' can indeed be noticed in films and TV series.
7/10
LG C6 handles tonal transitions very well. In most film scenes it was hard to notice obvious posterization problems. Both in dark parts of the image and in bright gradations the colours remain relatively smooth and do not break up into visible bands. That's very good news, because WOLED panels have not always been perfect in this respect. In the C6 it's noticeably better and during normal viewing this aspect of the picture shouldn't draw attention to itself.
One drawback, however, is dithering visible in near-black areas. Up close you can notice slight flicker and graininess in the darkest parts of the image. It's not as pronounced as on the Tandem OLED panel version, but it still occurs, so in this category we decided to deduct a few points from the C6.

Smooth transition function
Image without overscan on the SD signal
Here the LG C6 has taken a really big step forward. The TV uses the same processor found in the flagship G6, and in terms of image processing the two models are very close. That's a big plus, because in this area LG's processor this year performs excellently. The "Smooth Gradation" function works particularly well. With heavily compressed material it can effectively hide ugly tonal banding and artefacts that often appear, for example, in lower-quality streaming. It's best to leave it on the "Low" setting. Then the improvement is clear, and the TV doesn't yet start blurring fine detail. Higher levels smooth the image more aggressively, but can already remove some of the natural texture of objects on screen. Upscaling itself also performs very well. Lower-resolution content is properly sharpened, edges look clean, and the processor quite effectively reconstructs fine details. In that respect the C6 is really close to LG's best TVs and the differences compared with the G6 are small.

Maximum refresh rate of the panel: 165Hz

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, sport and consoles we’ll of course be limited to 120 Hz at most, but even then it’s hard to fault the motion clarity. As you’d expect from an OLED, the panel’s response time is near-instant. Moving objects therefore don’t leave the characteristic smearing you still see on LCD TVs. This is especially noticeable in sport and fast-paced games, where the picture remains very clean even during dynamic movement.
For movies and TV, LG has also included a motion smoothing system called TruMotion. In the user settings you’ll find two separate sliders. De-Judder is primarily for low-frame-rate material, namely movies and TV series at 24 fps. You can use it to slightly reduce the characteristic judder or increase it if you prefer a much smoother picture. De-Blur, on the other hand, is useful for higher-frame-rate content, mainly sports broadcasts and 50/60 fps TV.

There’s also an OLED Motion feature, a BFI-based solution that inserts black frames to improve motion clarity. On the C6 we don’t really 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 long focused heavily on gamers, and the C6 essentially lacks nothing important. The TV supports 4K at 120 Hz from consoles, and when connected to a PC it can even run at 165 Hz. On top of that there’s VRR from 40 to 165 Hz, ALLM and a properly functioning HGiG. Another big plus is support for Dolby Vision in games, so the Xbox Series X can use that format without giving up game mode. The package is rounded out by the Game Bar, which lets you quickly check key signal parameters and change settings without leaving your game. In terms of features alone, the C6 is one of those TVs it’s really hard to fault. 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 like a good gaming TV should. At 120 Hz we measured about 5 ms, so controller input is practically instantaneous. At 60 Hz the result increases to around 14 ms, but that's still a good figure. Latency is a bit higher in Dolby Vision. At 120 Hz it's about 14 ms, and at 60 Hz roughly 22 ms. In practice, during normal Xbox gameplay this isn't something that will really bother you.
| SDR | HDR | Dolby Vision |
|---|---|---|
| 1080p60: 14 ms | 2160p60: 14 ms | 2160p60 DV: 22 ms |
| 1080p120: 5 ms | 2160p120: 5 ms | 2160p120 DV: 14 ms |

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 clearly. You can therefore use it not only for gaming but also for regular work in Windows without much trouble. A limitation is the four‑subpixel panel layout. If you sit really close to the screen, you might notice slight coloured fringing on the edges of some fonts. It isn’t particularly bothersome and becomes practically invisible from a normal viewing distance.
The C6 also has a lot to offer PC gamers. From a PC you can use the full 165 Hz, and it also supports G-Sync, VRR and very low input lag, which is around 5 ms at the maximum refresh rate. Combined with the OLED’s lightning-fast response time, this delivers a very smooth, clean image with no visible motion blur. So if you plan to connect a powerful PC to the C6, the TV can comfortably serve as a large gaming monitor and will also work 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 actually rank among the best you can currently find in TVs. This is largely due to the OLED panel itself. Even if you sit well off to one side, the picture still retains good contrast and the colours don't lose much 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 extreme angles can you notice slight colour shifts, but during normal viewing it's hard to count that as any real issue. 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 facing 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 go grey or washed out. The C6 is also 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 starts to fall off more noticeably when a large part of the screen is white. That’s still a typical characteristic of OLEDs and it becomes noticeable with very bright content, for example winter sports. Overall, the C6 performs well in a normally lit living room. However, if the TV is going to sit opposite huge windows and spend most of the day fighting strong sunlight, 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 TV handled virtually all of the most popular video formats we copied onto a USB stick without any problems. There were no issues with high bitrates, subtitles or more demanding files, so it's hard to criticise it on that front. The only exception was material with a DTS audio track. That's not surprising, because the TV simply doesn't support that codec. Otherwise, the built-in player is good enough that most users will be fine without installing external apps or connecting an additional player.

In terms of sound the C6 is practically unchanged from last year’s C5. It still uses a 2.2-channel setup with a total output of 40 W, so a somewhat more solid base than many TVs that rely on simple 2.0 20 W arrangements. In practice the sound is quite good. Dialogue is clear, it doesn’t sound overly flat, and the additional speakers deliver a bit more bass than many basic TVs. Of course it still won’t replace a good soundbar, let alone a home theatre, but it’s more than enough for everyday TV viewing.
There’s a small step backwards, however, in the settings. LG removed some of the preset sound modes this year, which makes it a bit harder to tailor the sound to your preferences than on the previous generation. For that reason our rating is slightly lower, although the speakers’ capabilities remain practically unchanged. On the plus side it supports Dolby Atmos, the most popular surround-sound format in films and streaming right now. DTS support is still missing, which may matter mainly to people using their own movie libraries on discs or files.
