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 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.

Colours

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.

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 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.

For assessing the factory colour output we chose the Filmmaker Mode. If you’re encountering it for the first time, it’s a mode designed to reproduce a film or series as faithfully as possible. The TV then switches off most of the extra picture enhancement features, and the colours and luminance characteristics are intended to be as close as possible to what the creators of the material intended. And it must be admitted that The Frame 2026 performs really well in this respect straight out of the box. The biggest deviation is visible in the white balance. As brightness increases the blue starts to drop out and green increases slightly. As a result the picture shifts toward warmer tones. White is therefore not perfectly neutral, and in some scenes you can notice a slightly warmer cast.

The luminance response for both the gamma and EOTF curves looks good. Across most of the range they stay fairly close to the target, although in the darkest parts of the picture there is a larger deviation. In practice some details emerging from black may therefore be rendered a little more strongly. However, this is not an error that stands out during normal viewing. Overall Filmmaker Mode is a good starting point here. However the picture is a little too warm by default and not all hues land exactly where they should.

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.

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

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.

As with many of Samsung’s newer TVs, this one also uses the NQ4 AI processor, only the older, second-generation version. And you have to admit it handles digital image processing quite well. Lower-resolution material is sharpened effectively, and after upscaling to 4K it still looks natural. The TV can also somewhat "tidy up" weaker sources, like older recordings or lower-quality broadcasts. That doesn't, of course, mean it will suddenly turn poor footage into 4K, but at closer viewing distances the difference compared with simpler models with weaker processors is easy to spot. Edges are clearer, and fine details don't get lost as much to signal compression.

Samsung also offers a few additional image-enhancing features, but as usual it's best to use them sparingly. At stronger settings, noise reduction can very effectively reduce posterization, but it also noticeably interferes with the image. The picture then simply starts to look very artificial, for example by heavily smoothing characters' faces. So it makes the most sense with really poor sources when various types of noise are seriously distracting.

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.

Samsung again used a panel with a maximum refresh rate of 144 Hz. Refresh rates up to 120 Hz primarily offer greater possibilities with material that contains a lot of motion. The TV can use additional motion-smoothing systems that can improve fluidity in sports and other fast-moving 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, and consequently fairly pronounced motion blur. With rapidly moving objects, especially on a dark background, trails are easy to notice. There is also a slight doubling of edges, which can be visible even when additional motion-enhancement systems are switched off. We saw similar behaviour in last year's The Frame 2025, and it's a shame Samsung hasn't addressed this issue. 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 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.

In terms of gaming features, The Frame is practically on a par with Samsung’s top televisions. When a console is connected the TV automatically switches to Game Mode thanks to ALLM, so we do not have to change settings manually each time. There is also VRR, which matches the screen refresh rate to the number of frames produced by the console or PC. This helps avoid the characteristic screen tearing when frame rates drop. The Frame of course supports 4K at 120 Hz, so you can take advantage of the capabilities of the PlayStation 5 or Xbox Series X in games that offer higher frame rates. HGiG also works correctly. With HDR properly configured on the console, the TV does not try to brighten the picture further on its own, so bright effects in games are displayed as they should be. Samsung also includes a Game Bar. It is a handy menu you can bring up without leaving the game. There you can check VRR operation and the current frame rate, and quickly change the most important gaming-related settings. With a PC the possibilities are even greater, because the aforementioned Full HD mode lets you increase the refresh rate up to 240 Hz. There is essentially one feature missing that Samsung has already got us used to, namely Dolby Vision Gaming. Xbox owners will notice this most, as that console can use Dolby Vision in games. There is one more thing worth mentioning specific to this model. Its One Connect module has only one HDMI 2.1 port, so you must plug the console or PC into that port if you want to use 4K at 120 Hz. Fortunately Samsung did not combine this port with eARC. The soundbar can therefore be connected separately (3) and you still have a full HDMI 2.1 available for the console.
