LG OLED C6 (WOLED) vs Samsung The Frame 2026 (LS03H)

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.

Colours

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.

The Frame 2026 is a genuinely bright TV. Its peak brightness reaches around 650 nits and, importantly, it maintains similar levels regardless of the type of scene being displayed. It doesn’t really matter whether we’re watching a very bright full-screen image or just a small highlight occupying part of the screen. The backlight remains powerful, allowing bright parts of the image to stand out clearly.

This gives The Frame a solid foundation for HDR. Bright highlights can look impactful, and the picture doesn’t appear flat or overly dim. Unfortunately, there is a compromise. Without local dimming, the TV cannot darken the black areas surrounding very bright objects.

This is clearly visible in scenes 2 and 4 of our test procedure. Bright elements look impressive, but at the same time, the blacks around them become noticeably raised. As a result, the image loses some of its depth, especially when watching in a dark room. This is why The Frame performs best with HDR in bright and moderately bright scenes, where its high brightness works to its advantage. In darker scenes, the situation is quite the opposite.

Colours

The Frame also performs well when it comes to colour reproduction. As a QLED TV, it can display a wide colour gamut and produce rich, saturated colours. DCI-P3 coverage reaches around 94%, while BT.2020 comes in at around 72%. These are good results, and you can see the difference in actual content.

Colours look vivid without appearing washed out, particularly in bright and colourful scenes. Animations and other content with plenty of saturated colours can look really good on The Frame. With this type of material, the TV shows one of its stronger sides.

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.

For assessing the factory colour setup we chose the Filmmaker Mode. If you’re encountering it for the first time, it’s a mode designed to reproduce films and TV shows as faithfully as possible. The TV then turns off most additional image enhancers, and the colours and luminance response are intended to be as close as possible to what the creators intended. And it must be said that The Frame 2026 performs quite well in this respect straight out of the box. The biggest deviation is seen in the white balance. As brightness increases, blue starts to fall short and there’s a slight increase in green. As a result, the image shifts towards warmer tones. So white isn’t perfectly neutral, and in some scenes you can notice a subtly warmer cast.

The luminance response, both gamma and EOTF, looks pretty good. Through most of the range they stay fairly close to the target, although larger deviations are visible in the darkest parts of the image. In practice, some shadow details emerging from black may therefore be a bit more pronounced. However, it’s not an error that jumps out during normal viewing. Overall, Filmmaker Mode is a good starting point here. However, the factory picture is a bit too warm and not all hues land exactly where they should.

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.

After calibration we mainly managed to remove that warmer tint and better even out the white balance. We also smoothed the brightness response a bit, which made the picture more neutral and predictable. There are, however, things calibration won't fix. It's mainly the black performance, which comes from the backlight design and the lack of local dimming. In some scenes the blacks will therefore still be slightly lifted, and you just have to accept that. It's more a characteristic of this model than something you can fix with the settings. HDR is also somewhat limited. Samsung doesn't give full freedom to work across the widest colour gamut here, so not all colours can be reproduced perfectly. In normal viewing it will probably be hard to notice, but it's worth being aware of.

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.

As with many of Samsung’s newer TVs, this one also uses the NQ4 AI processor, albeit the older, second-generation version. I must admit it handles digital image processing quite well. Lower-resolution material is sharpened effectively, and when upscaled to 4K it still looks natural. The TV can also tidy up weaker sources a bit, such as older recordings or lower-quality broadcasts. That doesn’t, of course, mean it will suddenly turn poor footage into true 4K, but at close viewing distances the difference compared with simpler models with weaker processors is easy to spot. Edges are clearer and fine details aren’t lost as much to signal compression.

Samsung also provides a few extra picture-enhancing features, but as usual it’s best to use them sparingly. At stronger settings, noise reduction can very effectively reduce posterisation, but it also noticeably interferes with the image. The picture then starts to look quite artificial, for example by heavily smoothing faces. So these features make most sense with really poor sources when all the noise is very distracting.

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.

Samsung again used a panel here with a maximum refresh rate of 144 Hz. Refresh rates up to 120 Hz mainly offer greater flexibility with high-motion content. The TV can use additional motion smoothing systems that can improve smoothness in sports and other fast-paced content. However, a high refresh rate alone does not solve everything. The Frame still uses a VA panel, which has a fairly slow response time, resulting in quite pronounced motion blur. With fast-moving objects, especially against dark backgrounds, the trails are easy to notice. There's also a slight double-imaging of edges, which can be visible even after turning off additional motion enhancement systems. We already saw similar behaviour in last year's The Frame 2025, and it's a shame Samsung hasn't fixed this. The 144 Hz itself provides a good foundation, but the panel's response time still limits this TV.

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.

When it comes to gaming features, The Frame is practically on par with Samsung’s flagship TVs. Once a console is connected, the TV automatically switches to Game Mode thanks to ALLM, so there’s no need to change the settings manually every time. There’s also VRR, which matches the screen’s refresh rate to the frame rate generated by the console or PC. When the frame rate drops, this helps prevent the characteristic screen tearing that can otherwise occur.

The Frame naturally supports 4K at 120Hz, allowing you to take advantage of higher frame rates on the PlayStation 5 and Xbox Series X. HGiG also works correctly. Once HDR has been properly calibrated on the console, the TV doesn’t try to additionally brighten the image on its own, so bright highlights in games are displayed as they should be.

Samsung also includes its Game Bar. This quick-access menu can be opened without leaving the game and lets you check things like VRR operation or the current frame rate, while also giving you quick access to the most important gaming settings. PC users get even more flexibility, as the Full HD mode mentioned earlier allows the refresh rate to be increased all the way up to 240Hz.

There is really only one feature missing, and by now it’s something we’ve come to expect from Samsung TVs: Dolby Vision Gaming. Xbox owners will notice this the most, as Xbox consoles can actually use Dolby Vision in supported games.

There is one more limitation worth mentioning that applies specifically to this model. The One Connect box has only one HDMI 2.1 port, so this is the only input you can use for a console or PC if you want to play at 4K 120Hz. Fortunately, Samsung hasn’t combined this port with eARC. This means you can connect a soundbar separately to HDMI 3 and still keep the full-bandwidth HDMI 2.1 port available for your console.
