TCL C855 vs Samsung The Frame 2026 (LS03H)

The TCL C855 delivers a highly varied HDR effect. At times, the television truly excels, while at other moments, it appears reminiscent of a low-end model equipped with FALD backlighting. Inconsistency is frequently found with this brand, so it didn’t come as a surprise. The first and last scenes, which feature large light elements, are nothing short of spectacular, boasting brightness levels of 1470 and 1820 nits, respectively. Such brightness can make viewers squint their eyes, allowing them to feel the extraordinary dynamism of the scene. It genuinely immerses the audience, creating a sensation of being inside the movie itself. However, the situation shifts dramatically when small or subtle elements with high luminance appear against a dark background. In these instances, the TCL C855 significantly reduces brightness to levels as low as 240 nits to mitigate halo effects. This reduction is disappointing, as it can make the movie appear as if it was not filmed in HDR. Despite these shortcomings, the HDR effect on the TCL C855 enhances the viewing experience during dynamic scenes, making it feel more engaging and allowing the viewer to feel part of the action. Even with smaller high-luminance elements, the television retains details without excessive dimming. Additionally, the TCL C855 adjusts image brightness according to scenes with rich detail, further enhancing viewing comfort.

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.

The best factory mode for the TCL C855 is the "Film" setting, and all our tests were conducted using this mode. However, like many predefined modes, it has flaws that should be addressed to achieve an image closer to the producer's original vision. In our examination of the colour characteristics for both SDR and HDR materials, issues were found.

Focusing first on SDR content, there is a noticeable dominance of green in the white balance, which leads to an unpleasant greenish tint across the entire image. The gamma chart, crucial for image contrast, shows a significant deviation from the reference line marked at 2.4. Initially, there is a pronounced spike in the measured value, resulting in an over-contrasted image where details can merge into a dark blob. This condition persists for nearly 20% of the chart before it dips below the reference line, causing the image to brighten and resulting in a substantial drop in contrast.

In HDR materials, the factory mode performs somewhat better; the white balance appears more balanced overall, although the green tint resurfaces in the latter half of the spectrum. When we look at the Electro-Optical Transfer Function (EOTF) curve—unlike gamma, which reflects contrast—we identify two main errors: the darkest scenes are too dark, while the brightest ones become overexposed. This discrepancy was evident in our review of the scene from the movie "Pan," further illustrating the TCL C855's HDR performance issues.

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.

TCL, like most manufacturers, offers advanced calibration tools within its televisions. These include both 2-point and 20-point adjustments for grayscale, as well as a comprehensive colour management system. As a result, we achieved impressive results in SDR materials, bringing the image significantly closer to the reference standard. We successfully eliminated both the green tint and the gamma issue, although a slight "kink" at the very beginning of the gamma curve still persists.

In contrast, the situation with HDR materials was less favourable, as the TCL C855 did not allow for precise modelling. We were only able to make minor adjustments to the EOTF curve while significantly enhancing the overall colour accuracy. This limitation suggests that while calibration tools are effective, they may require further refinement for optimal HDR performance.

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.

Once again, we will take a look at the function of smoothing tonal transitions, but this time also image scaling. The latter is particularly important when watching materials of lower quality, such as some television programs or older films. We will focus on the function responsible for tonal transitions. Interestingly, just like in the scenes from the previous test where it performed excellently and smoothed out practically all the inconsistencies, here it had issues. Using the menu responsible for the operation of this function, we found that no setting—even the strongest—was helpful.

Image scaling in TCL C855 is defined as one of the best we have had the opportunity to test so far. The image is sharp, but in a way that could be described as natural to our eye. Even small, fine branches do not have jagged edges, and there is no white halo around figures, a characteristic of weaker scaling systems.

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 maximum refresh rate you can set on the TCL C855 is 144 Hz. Naturally, this is only possible after connecting the TCL C855 TV to a very powerful PC. Otherwise, we will be operating at a maximum refresh rate of 120 Hz, which is recommended if we want to watch primarily sports or materials with a lot of motion dynamics. For those who require high image fluidity, the manufacturer has implemented a multi-stage motion smoother. It is divided into two separate sliders which control the sharpness of moving images (Motion Blur Reduction) and flicker (Flicker Reduction). Both sliders can be adjusted from 0 to 10, with each level affecting the degree of fluidity, so everyone can find their sweet spot. We present a setting that allows for slight smoothing without the soap opera effect. The matrix of the TCL C855 features a very good response time. This is particularly important since VA panels often struggle with the so-called ghosting effect, where a black halo can be observed behind a fast-moving object. where a black halo can be observed behind a fast-moving object.

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.

The TCL C855 TV has fully-featured HDMI 2.1 ports, boasting a full bandwidth of 48 Gb/s. During our testing, we confirmed the seamless operation of all functions included in this connection standard. As highlighted, all checkboxes are illuminated in green, a feature that will undoubtedly be appreciated by gamers, whether on consoles or those using the TV as a computer monitor. Additionally, the TCL C855 supports both AMD FreeSync and NVIDIA's G-Sync, which can be easily activated in the graphics card settings. Those with powerful configurations can feed a 144 Hz signal to the C855, which handles this effortlessly. It is also worth noting the implementation of the HGIG mode, which can be excessively bright due to the shortcomings of the "Game" mode, making proper configuration on the screen challenging. Fortunately, the TV excels with the Dolby Vision format.

TCL, as one of the pioneering manufacturers, has equipped its televisions with a special GameBar, allowing for extensive adjustment of settings "on the fly" without the need to exit the game. This feature includes options like an additional crosshair grid, black level correction, and settings designed for individuals with disabilities. The image showcases the next generation of this solution.

In summary, the TCL C855 TV is an ideal choice for those seeking a screen for all forms of electronic gaming. With comprehensive features supporting such entertainment, it provides an extremely engaging experience. It is also important to emphasise that it maintains very low input lag, regardless of the selected settings, including when using the Dolby Vision HDR format.

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.
