TCL C855 vs Samsung The Frame 2025 (LS03F)

TCL C855 delivers a highly varied HDR effect. On one hand, the television truly shines, while on the other, it resembles a lower model with FALD backlighting. Such a state of affairs is regularly observed with this brand, so it was not a surprise for us. The first and last scene, which has large light elements, looks phenomenal, "shining" with brightness levels of 1470 and 1820 nits respectively. Such effects will certainly make many people squint, while simultaneously feeling the extraordinary dynamism of the scene itself. You can truly feel as if you were inside the movie. The situation drastically changes when small or minor elements with high luminance surrounded by black appear on the screen. The TCL C855, to avoid the halo effect, significantly reduces brightness to a level of even 240 nits, which is a disappointing outcome, causing the film to not look like it was shot in HDR. The HDR effect in TCL C855 makes watching dynamic scenes more engaging, and the viewer can feel like they are part of the action. Even with smaller elements of high luminance, the television manages to maintain details without excessive dimming. Moreover, the TCL C855 test shows that the brightness of the image is adapted to scenes with a large amount of detail, increasing 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 film scenes are quite another story. When watching HDR materials in natural conditions, The Frame 2025 maintains very good results. In most film scenes, peak brightness stayed at around 550–650 nits. This is enough to feel the difference between standard picture and that in HDR quality – bright highlights, reflections on water, or moonlight look distinct and impressive.

It's also worth noting that the LS03F is a QLED television, which translates to solid colour saturation. The coverage of the DCI-P3 colour space reaches about 92%, allowing for vibrant, intense colours in HDR content. It's not 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 "Film," and it is on this mode that we conducted all our tests. However, like every mode predefined by the manufacturer, it had flaws that are worth correcting to achieve an image that is as close as possible to what the film producer intended. We will look at the colour characteristics in both SDR and HDR materials. Taking the former into account, we see a clear dominance of green in the white balance, which, as you might guess, gave an unpleasant greenish tint to the entire image. Examining a very important gamma chart, responsible for the contrast of the image, we see a significant deviation from the reference line marked at 2.4. From the left, we can observe a strong spike in the measured value, which at this point caused contrast exaggeration and blending of details into a dark blob. This state of affairs persisted for quite a while, up to 20% of the chart’s value, before then diving below the reference. This, in turn, meant that the image was brightened and contrast decreased significantly. The factory mode performed somewhat better in HDR materials, as the white balance looked quite good, except for the second half, where green again took over. Looking at the EOTF curve, which, unlike gamma, shows the rate of brightness increase, we see primarily two errors: the darkest scenes were too dark, and the brightest ones were overexposed. This, by the way, could be observed in the scene from the film "Pan" in the check paragraph for the TV's HDR.

When it comes to picture quality right out of the box, even in Filmmaker mode, which is supposed to be the closest to reference, there were some issues. In both HD and 4K HDR content, we noticed clear deviations in white balance. The picture was heavily skewed towards red and blue, giving the screen a distinctive pinkish hue. This effect was most noticeable in bright scenes – for example, in shots with a lot of white, where neutral light should naturally dominate. In such moments, the screen clearly took on pink tones, which is also evident in the attached comparative photo. As for brightness characteristics – it wasn't as bad as one might expect given such colour inaccuracies. Analysis of the gamma curve and EOTF showed a slight brightening of the image compared to the reference, but not enough to drastically spoil the viewing experience.

TCL, just like the vast majority of manufacturers, provides advanced calibration tools in its televisions. Here we find 2- and 20-point grey scale adjustments as well as an advanced colour management system. The results, as you can see, are very good and in SDR materials we have significantly approached the reference image. We eliminated both the green tint and the gamma issue, although there is still a slight "kink" at the very beginning. It went a bit worse with HDR materials, which the television ChooseTV C855 did not allow us to model properly. We only managed to slightly adjust the EOTF curve and significantly improve the colours themselves.

After calibration, the movie mode gained a completely new quality. The issue of the pink tint, which was previously clearly visible, especially in bright scenes, has been effectively eliminated. Colours started to look significantly more natural, and the white balance no longer dominated the rest of the image. It was no longer the same oversaturated "picture from a box" – everything took on coherence and a cinematic character. Additionally, the tendency of the TV to slightly brighten scenes, previously visible in the EOTF curve analysis, has been partially corrected. Of course, within the limits of what the design allows without local dimming – it's difficult to speak of perfect brightness management here. Nevertheless, the final effect was definitely closer to what one might expect from a mode named Filmmaker.

Once again, we will 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 TV programs or older films. We will focus on the function responsible for tonal transitions. Interestingly, just like in the scenes in the previous test, it performed splendidly and smoothed out practically all the choppiness, but here it had problems. Using the menu responsible for the operation of this function, we found that none - not even the strongest - setting helped.

The image scaling in TCL C855 is characterised 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 contours, and there is no white halo around figures, which is characteristic of weaker scaling systems.

LS03F is equipped with an NQ4 processor, which is responsible for improving image quality – especially in lower-quality materials. In practice, it works surprisingly well, particularly when it comes to older content and recordings with lower resolution. Activating the "noise reduction" feature delivers noticeable results. 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 – earlier, 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 happens in a much more acceptable way. Textures of materials, skin, or fabric details are not as 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 appeal to everyone. On the other hand, it's no longer such an aggressive intervention as in previous models. It's also worth mentioning that the LS03F may struggle with very weak signals – for example, from VHS tapes or low-resolution video. In such cases, we noticed slight clipping of the image at the edges – the 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 that we can set on TCL C855 is 144 Hz. Naturally, this is only possible when connecting the TCL C855 TV to a very powerful PC. Otherwise, we will operate at a maximum refresh rate of 120 Hz, which is recommended if we primarily want to watch sports or content with a high level of motion dynamics. For those who require high fluidity of image, the manufacturer has implemented a multi-level motion smoother. It has been divided into two separate sliders that adjust the sharpness of moving images (Blur Reduction) and judder (Judder Reduction). Both sliders can be set in the range of 0 to 10, with each level affecting the degree of smoothing, so everyone can find their sweet spot. We present a setting that allows for slight smoothness without the soap opera effect.

The panel of TCL C855 features a very good response time. This is especially important, as VA panels often have issues with so-called ghosting, which is the effect where a black halo can be noticed behind a fast-moving object.

The new feature in The Frame for 2025 is a 144 Hz refresh rate display. Yes – in a television primarily associated with displaying works of art, you can now not only watch Van Gogh, but also comfortably play on a console or follow fast-paced sporting events. This is a significant step towards greater versatility. In the case of Samsung movies, as usual in models with a 120 Hz display and above, it allows you to adjust motion fluidity according to your preferences. You can set a more cinematic reproduction that maintains frame rate or opt for complete image smoothing. The range of options is broad, allowing you to tailor the effect to your tastes – regardless of whether the screening is meant to look like classic cinema or a performance on a modern theatre panel.

*this part of the test refers to the model LS03FAU in sizes 55 and 65 inches, which is equipped with a 144Hz display; the sizes 43 and 50 inches have 60Hz displays, and consequently perform much worse in terms of motion fluidity.

The TCL C855 television is equipped with full HDMI 2.1 ports with a bandwidth of 48 Gb/s. During our tests, we confirmed the seamless operation of all functions that come with this standard. As you can see, all the checkboxes light up green, which will certainly be appreciated by gamers, both console and those using the television 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. Users with very powerful setups can provide a 144 Hz signal to the C855, which the television handles effortlessly. It's also worth mentioning the implementation of the HGIG mode, which, due to the shortcomings of the "Game" mode, is overly bright, making it difficult to configure properly on-screen. Fortunately, the television performs excellently with the Dolby Vision format.

The TCL C855, as one of the first manufacturers, has equipped its televisions with a special GameBar feature that allows extensive setting changes on the fly, without the need to exit the game. It includes functions such as an additional crosshair grid, black level correction, and settings for individuals with disabilities. In the photo, we see the next generation of this solution.

In summary, the TCL C855 television will be an ideal solution for those looking for a screen for any kind of electronic gaming. With all the features supporting such entertainment, it is incredibly engaging. It should also be emphasized that it has very low input lag, regardless of the selected settings, including with the Dolby Vision HDR format.

As we mentioned earlier – although The Frame likely displays images and artwork for most of the time, Samsung recognised that a Van Gogh fan could just as easily be an avid gamer. And it must be said that The Frame 2025 has almost everything to become a fully-fledged gaming TV.

Onboard, we find support for ALLM (Auto Low Latency Mode) and Variable Refresh Rate (VRR) thanks to the implementation of a single HDMI 2.1 port. The TV handles lower resolutions at higher refresh rates effortlessly and features an expanded Game Bar – already known from other Samsung models – which allows for quick preview and adjustment of key gaming-related settings. For this, it gets extra points from us. Noteworthy is also the proprietary motion smoother, Auto Motion Plus Game, which – and this is worth emphasising – works without increasing input lag. Samsung remains the only manufacturer that has managed to implement this feature in a practically unnoticeable way regarding delays. The result? Much better fluidity in games, especially those that struggle to maintain a stable 60 frames. This solution can genuinely improve gaming comfort in more demanding titles – particularly on consoles that don’t always manage full fluidity, especially in AAA games.

As for the downsides – the lack of Dolby Vision is already something we consider standard in Samsung TVs, so there’s not much to specifically nitpick here. However, the problem lies elsewhere. In the latest version of the Tizen system, the HGiG option has disappeared. Literally – it’s gone. This is a significant inconvenience when configuring the 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 needs to be fixed as soon as possible. We’re talking about a brand that has set standards for gaming on TVs for years. If HGiG returns – and we hope it does – The Frame LS03F can confidently aspire to be a proper gaming TV. Not only as a decoration on the wall, but as equipment that truly enhances the gaming experience.
