TCL C855 vs Samsung The Frame 2025 (LS03F)

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 LS03F is a television that can surprise with its brightness. The maximum luminance reaches around 650 nits, which already looks solid on paper. But as we know, lab tests are one thing, and real movie scenes tell a completely different story. When watching HDR content in natural conditions, The Frame 2025 maintains very good results. In most film scenes, peak brightness remained at levels of 550–650 nits. This is enough to feel the difference between standard image quality and that of HDR – bright highlights, reflections on water, and moonlight appear clear and impressive.

It’s also worth noting that the LS03F is a QLED television, which translates to solid color saturation. The coverage of the DCI-P3 color space reaches about 92%, allowing for vibrant, intense colors in HDR content. It may not be at the level of top premium models, but for a lifestyle screen, the result truly deserves recognition.

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.

When it comes to image quality right out of the box, even in Filmmaker mode, which is supposed to be the closest to reference, there were issues. In both HD and 4K HDR content, we noticed noticeable deviations in white balance. The image was heavily skewed towards red and blue, giving the screen a characteristic rosy tint. This effect was most visible in bright scenes – for example, in shots with a lot of white, where neutral light should naturally dominate. In such moments, the screen clearly leaned towards pink tones, which can also be seen in the attached comparison photo. As for brightness characteristics – it wasn't as bad as one might expect given such color inaccuracies. Analysis of the gamma curve and EOTF showed a slight brightening of the image compared to the reference, but not enough to drastically affect the perception of the material.

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, the movie mode gained a completely new quality. The issue of pink tint, which had previously been clearly visible, especially in bright scenes, was effectively eliminated. Colors began to look much more natural, and the white balance no longer dominated the rest of the image. It was no longer the same exaggerated “box picture” – everything gained coherence and a cinematic character. Additionally, the tendency of the television to slightly brighten scenes, previously visible in the EOTF curve analysis, was partially corrected. Of course, this was within the limits of what the design allows without local dimming – it’s hard to speak of perfect brightness management here. Nevertheless, the final effect was definitely closer to what one would expect from a mode called Filmmaker.

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.

The LS03F is equipped with the NQ4 processor, which is responsible for improving image quality—especially in lower-quality materials. In practice, it works surprisingly well, particularly with older content and recordings with lower resolution. Activating the "noise reduction" feature yields noticeable effects. The television effectively smooths tonal transitions and removes digital noise that can appear in darker areas of the image. Compared to previous generations, there is a clear improvement—previously, this feature often smoothed everything too much, including details that it shouldn't have removed. In this year's model, the smoothing still occurs, but it is done in a much more acceptable manner. Textures of materials, skin, or fabric details are no longer so heavily muted as before—the image retains more naturalness. However, this does not change the fact that film grain is still removed by the television, which may not be to everyone's liking. On the other hand, it is no longer as aggressive an intervention as in previous models. It is also worth mentioning that the LS03F may struggle with very weak signals—such as recordings from VHS tapes or video in low resolution. In such cases, we noticed slight clipping of the image at the edges—so-called overscan. This can lead to situations where a small part of the image (e.g., subtitles at the bottom edge) gets cut off.

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.

A novelty in The Frame for 2025 is the panel with a refresh rate of 144 Hz. Yes – in a television primarily associated with displaying artwork, you can now not only watch Van Gogh but also comfortably play on a console or follow dynamic sports action. This is a definite step towards greater versatility. In the case of Samsung films, as usual in models with a 120 Hz panel and above, it allows you to adjust motion smoothness according to your own preferences. You can set a more cinematic representation while maintaining frame rate or opt for full motion smoothing. The range of options is wide, allowing you to tailor the effect to your taste – whether the viewing experience is meant to resemble classic cinema or a presentation on a modern theater panel.

*this part of the test refers to the model LS03FAU in sizes 55 and 65 inches, which is equipped with a 144Hz panel; the 43 and 50-inch sizes have 60Hz panels, and therefore perform much worse in terms of motion smoothness.

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.

As we mentioned earlier – although The Frame likely displays images and works of art most of the time, Samsung has recognized that a Van Gogh enthusiast can just as easily be an avid gamer. And it must be admitted that The Frame 2025 has almost everything it needs to become a fully-fledged gaming television.

On board, we find support for ALLM (automatic game mode) and variable refresh rate (VRR) thanks to the implementation of one HDMI 2.1 port. The television handles lower resolutions at higher refresh rates without any issues and features an expanded Game Bar – already known from other Samsung models – which allows for quick previewing and changing of the most important gaming-related settings. For this, it earns additional points from us. The proprietary motion smoother Auto Motion Plus Game also deserves special mention, which – and it's worth emphasizing – works without increasing input lag. Samsung remains the only manufacturer that has managed to implement this feature in a practically noticeable way in terms of delays. The result? Much better fluidity in games, especially those that struggle to maintain stable 60 frames. This solution can realistically improve the gaming experience in more demanding titles – especially on consoles that don’t always manage full fluidity, especially in AAA games.

As for the downsides – the lack of Dolby Vision is already considered standard in Samsung televisions, so there's nothing to particularly complain about here. However, the problem is something entirely different. In the latest version of the Tizen system, the HGiG option has disappeared. Literally – it's not there. This is a significant setback when configuring a console for proper HDR content display in games. It’s hard to understand why such a decision was made, but one thing is certain – this should be fixed as soon as possible. We are talking about a brand that has set standards for gaming on televisions for years. If HGiG comes back – and we hope that it will – The Frame LS03F can confidently aspire to be a true gaming television. Not just as a decoration on the wall, but as equipment that really provides joy in gaming.
