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

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.

Colors

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.

The Frame 2026 is genuinely a bright TV. Its peak brightness reaches about 650 nits and, importantly, similar values are maintained regardless of the type of scene being displayed. So it doesn’t matter much whether we’re watching a very bright full-screen shot or just a small bright element occupying part of the screen. The backlight always has a lot of power, so bright portions of the image are strongly illuminated. That gives The Frame a solid foundation for HDR. Bright highlights can stand out, and the picture doesn’t look flat or too dark. Unfortunately, this is not a solution without compromises. Because it lacks local dimming, the TV cannot darken the blacks next to very bright elements.

This is clearly visible, among other things, in scenes 2 and 4 from our test procedure. Bright areas look intense, but at the same time the blacks around them become noticeably lifted. The picture loses depth as a result, especially when watching in the evening. For that reason The Frame performs best with HDR in bright and moderately bright scenes. There the high backlight brightness works in its favor. In darker shots the situation is the opposite.

Colors

The Frame also performs well in terms of color. It’s a QLED TV, so it can display a wide color gamut and show richly saturated colors. DCI-P3 coverage is around 94%, and BT.2020 about 72%. Those are good numbers and you can see them while watching. Colors are vivid and do not look washed out. It looks best in bright, colorful scenes. Animations or cartoons with lots of saturated hues can look really good on The Frame. In such material the TV shows one of its stronger points.

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.

To evaluate the out-of-the-box colors we chose Filmmaker Mode. If you’re encountering it for the first time, it’s a mode designed to present a movie or series as faithfully as possible. The TV then turns off most additional picture enhancers, and the colors and luminance characteristics are meant to be as close as possible to what the content creators intended. I have to admit that the The Frame 2026 already performs quite well in this regard straight out of the box. The biggest deviation is visible in the white balance. As brightness increases, blue starts to drop off and green increases slightly. As a result the image shifts toward warmer tones. White is therefore not perfectly neutral, and in some scenes you can notice a slightly warmer overall cast.

The luminance response — gamma or EOTF — looks good. Across most of the range they stay fairly close to the target, though in the darkest parts of the image there is a larger deviation. In practice, some details emerging from black may therefore appear a bit more pronounced. That said, it’s not a flaw that jumps out during normal viewing. Overall, Filmmaker Mode is a good starting point here. However, the factory image is a bit too warm 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 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.

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

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.

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.

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.

Samsung again used a panel with a maximum refresh rate of 144 Hz here. Refresh rates up to 120Hz primarily offer more headroom for material with a lot of motion. The TV can use additional motion interpolation systems that can improve smoothness 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 relatively slow response time, and consequently fairly pronounced motion blur. With fast-moving objects, especially on a dark background, motion trails are easy to notice. There's also a slight doubling of edges, which can be visible even with the additional motion processing systems turned off. We already saw similar behavior in last year’s The Frame 2025, and it’s a pity Samsung hasn’t fixed that element. The 144 Hz itself provides a good foundation, but the panel’s response time still limits this TV.

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.

In terms of gaming features, The Frame is practically on par with Samsung's top TVs. When you connect a console the TV automatically switches to game mode thanks to ALLM, so you don't have to change settings manually each time. There's also VRR, which matches the display's refresh rate to the frames being produced by the console or PC. During drops in smoothness this helps avoid the characteristic screen tearing. The Frame of course supports 4K at 120 Hz, so you can take advantage of the PlayStation 5 or Xbox Series X in games that offer higher frame rates. HGiG also works correctly. With HDR set up properly on the console the TV doesn't try to brighten the image on its own, so bright effects in games are shown as they should be. Samsung also includes a Game Bar. It's a handy menu you can bring up without leaving the game. There you can check things like VRR and the current frame rate, and quickly change the most important gaming settings. For PC use the options are even greater, since the mentioned Full HD mode allows raising the refresh rate up to 240 Hz. There is really only one feature missing that Samsung has already spoiled us with, and that's Dolby Vision Gaming. Xbox owners will notice this the most, because that console can use Dolby Vision in games. There's one more thing worth mentioning that applies specifically to this model. Its One Connect module has only one HDMI 2.1 port, so that's the only port you can use for a console or PC if you want 4K 120 Hz. Fortunately Samsung didn't tie that port to eARC. You can therefore connect a soundbar separately (3) and still have a full HDMI 2.1 port available for the console.
