TCL C855 vs Samsung The Frame Pro

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.

Samsung The Frame Pro is one of the relatively bright televisions. In synthetic tests, we managed to achieve values around 900 nits, which is quite a decent result for a lifestyle model. In full-screen scenes, such as the frame from the movie The Meg or the opening sequence in Life of Pi, the brightness maintained a level of 700–800 nits. These values allow you to fully enjoy the HDR effects and capture their cinematic magic. However, the situation complicates when smaller, point light sources appear on the screen. The edge lighting used here, equipped with the ability to local dim whole strips, does not handle them very well. It happens that small elements are overly darkened, which weakens the effect, or conversely – they become heavily brightened, but at the cost of losing black depth in that part of the image. This can be compared to light halos reminiscent of a laser beam spreading in dense fog – an effect that is visible and bright but at the same time not very natural and distracting. Fortunately, the colour aspect performs better. Thanks to the use of a quantum dot filter (QLED), the colours are saturated, and the reproduction of the DCI-P3 palette reaches over 92%. Generally, movies or series watched in HDR on The Frame Pro present a rich colour palette, even if contrast and the performance of the lighting algorithms can sometimes draw our attention away.

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.

The best results were, of course, achieved in Filmmaker mode, which immediately showed that Samsung had put effort into the factory settings. In SDR content – the most commonly viewed materials – The Frame Pro performed really well. The white balance and gamma were almost perfectly set, making the image look natural and cohesive. Yes, there were some noticeable errors, particularly in skin tones and reds, which could be overly saturated, giving everything a slightly "warmed up" character, but in everyday use, it didn't hinder the viewing experience too much. For HDR content, the situation was similar regarding the white balance. It was at a good level, however, the biggest issue turned out to be managing brightness. The EOTF curve was set in such a way that in many scenes the image appeared blown out, and the brightest areas lost detail and resulted in uniform patches of light. This severely affected realism and made colours appear very oversharpened. Fortunately, Samsung provides the option for manual adjustment of the curve in their TVs, so we opted for calibration and its results can be seen below.

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 SDR mode looks almost perfect. We managed to eliminate the overly intense red saturation that previously gave the image a somewhat excessively warm character. The colours became more balanced, which translated into a natural and pleasant viewing experience for everyday content – from television to movies and series from streaming services or materials on YouTube. In HDR mode, the EOTF curve required the most work, as the factory settings caused excessive clipping of the entire image. The calibration significantly helped to "tame" this issue – the image stopped being overexposed, and details in the bright areas became more visible. Of course, the limits are set by the design of the television itself, as edge lighting reveals its limitations, and even the smallest elements of light can still appear overly bright or blend into the background. However, this is a matter of technology, not just calibration. After the correction, The Frame Pro is much more enjoyable to watch, and it is definitely worth considering if you want to make the most of the television's capabilities.

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.

Although in 4K HDR materials the fluidity of tonal transitions in the ChooseTV Pro is not a problem at all, naturally with weaker signal quality – such as with television, HD materials, or older Full HD films – imperfections may occur. Therefore, it's crucial how the television handles these limitations thanks to the image processor. The noise reduction feature works really effectively here. At the medium setting, it eliminates unwanted bands or artifacts, smoothing the image in a visible yet not overdone way. However, it's important to remember that Samsung has a tendency to be aggressive – even at the lowest level of this feature, it can "eat" film grain. So, it's wise to use it with caution and adjust the settings according to the material being watched.

The upscaling itself is of a high standard. The ChooseTV Pro effectively boosts older materials to a native 4K resolution, maintaining good sharpness and clarity. Movies and series in lower quality simply look better here. However, it's worth mentioning a minor downside – typical for many Samsung televisions. With very old sources in poor quality, you may notice some cropping of the image edges on the left side of the screen. It's not a problem that will ruin the viewing experience, but it's good to know that it may occur.

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 fluidity of movement in The Frame Pro is not only due to the panel itself, which operates at a refresh rate of up to 144 Hz, but also the image processor and motion smoothing system. It is thanks to this that we can adjust the way movies or sports broadcasts are displayed to our own preferences. Available are sliders for blur reduction and motion judder reduction – the first function enhances the sharpness of fast movements, while the second helps to soften the effect of the "jumping" image during camera pans. Everyone can choose between a cinematic character of motion and a smoother, more "television" style.

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.

Samsung The Frame Pro doesn’t pretend to be just a “living room” TV; gamers will also find something for themselves here. The manufacturer has ensured a full package of gaming features: we have support for variable refresh rate (VRR), auto low latency mode (ALLM), refresh rates up to 144 Hz, and compatibility with both G-Sync and FreeSync Premium Pro. Additionally, there’s the well-known Game Bar panel, which is a quick menu where you can check key parameters on-the-fly – from refresh rates to active image processing modes. Are there downsides? Yes, The Frame Pro doesn’t support Dolby Vision in game mode, but it’s hard to consider this a serious issue – most gamers use HDR10 anyway... so the HGIG mode. Exactly. The biggest surprise was the latest software update. Samsung... completely removed this option from The Frame PRO. In practice, this means that the TV independently interprets HDR tone mapping in games, and the user cannot enable settings designed with consoles in mind. This is a step backwards, which may disappoint more aware gamers hoping for full compliance with HGiG guidelines. We can only hope that this mistake will be quickly fixed.

An interesting feature of The Frame Pro is also the unusual placement of HDMI 2.1 ports. We have as many as five at our disposal – four are located in the One Connect module, and the fifth, in micro HDMI form, is located directly on the TV. This solution is quite unusual but very practical. Samsung clearly suggests that this is the port to connect your console or computer. Why? Because it minimises any potential delays associated with communication through the wireless One Connect, and in gaming, every millisecond counts. We have written separately about input lag, but we can reveal here that by connecting the equipment directly to the TV, we get the absolute maximum response speed from it.
