TCL C855 vs Samsung The Frame Pro

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.

Samsung The Frame Pro belongs to relatively bright televisions. In synthetic tests, we managed to achieve values around 900 nits, which, for a lifestyle model, is quite a decent result. In full-screen scenes, such as the frame from the movie The Meg or the opening sequence in Life of Pi, brightness remained at levels of 700–800 nits. These are values that allow you to fully enjoy 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 locally dim entire strips, does not handle them very well. It sometimes happens that small elements are excessively dimmed, which weakens the effect, or on the contrary – they are significantly brightened, but at the cost of losing black depth in that part of the image. This can be compared to light glows resembling the spread of a laser beam in dense fog – the effect is visible and bright, but at the same time, it is not very natural and distracts our attention. Fortunately, the color aspect performs better. Thanks to the use of a quantum dot filter (QLED), the colors are saturated, and the reproduction of the DCI-P3 palette exceeds 92%. In general, movies or series watched in HDR on The Frame Pro present a rich color palette, even if the contrast and the operation of the backlight algorithms can sometimes distract our attention.

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.

The best results were, of course, achieved in Filmmaker mode, which immediately showed that Samsung paid attention to the factory settings. In SDR content – the type of content most often viewed – The Frame Pro performed really well. White balance and gamma were almost perfectly matched, making the image look natural and consistent. Yes, there were some noticeable errors, especially in skin tones and reds, which could be overly saturated, giving everything a slightly “warmed up” character, but in everyday use, this did not significantly affect the viewing experience. In the case of HDR content, the situation was similar regarding white balance. It was at a good level; however, the biggest problem turned out to be brightness management. The EOTF curve was set in such a way that in many scenes the image appeared to be overexposed, and the brightest areas lost details and turned into solid patches of light. This severely undermined realism and made the colors appear strongly over-sharpened. Fortunately, Samsung provides the option for manual adjustment of the curve in its televisions, so we opted for calibration, and its results can be seen below.

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 SDR mode looks simply perfect. We managed to eliminate the overly strong red saturation that previously gave the picture a somewhat excessively warm character. The colors became more balanced, which translated to a natural and pleasant reception of daily content – from television to movies and series from streaming or materials on YouTube. In HDR mode, the EOTF curve required the most work, as it originally caused excessive burning of the entire image. Calibration largely helped to "tame" this problem – the image stopped being overexposed, and details in bright areas became more visible. Of course, the limits are set by the television's own design, as edge lighting reveals its limitations, and even the smallest elements of light can still be oversaturated or blend into the background. However, this is a matter of technology, not calibration itself. After the correction, The Frame Pro is much more enjoyable to watch, and it's definitely worth opting for if you want to make the most of your television's capabilities.

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.

While the smoothness of tonal transitions in 4K HDR content on The Frame Pro is not a problem at all, naturally with weaker signal quality – from television, HD content, or older Full HD films – imperfections may occur. Therefore, it is crucial how the television handles these limitations thanks to its 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 noticeable but not overly exaggerated way. However, it should be noted that Samsung tends to operate aggressively – even at the lowest setting of this feature, it can "eat" film grain. It is therefore advisable to use it with caution and adjust the settings to the material being viewed.

The upscaling itself is at a high level. The Frame Pro can effectively upscale older materials to native 4K resolution while maintaining good sharpness and readability. Movies and series in lower quality simply look better here. However, it is worth mentioning a minor drawback – typical for many Samsung televisions. With very old sources of poor quality, you may notice cropping of the image edges on the left side of the screen. This is not a problem that will ruin the viewing experience, but it is good to know that it may occur.

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.

The smoothness of motion in The Frame Pro is ensured not only by the panel, which operates with a refresh rate of up to 144 Hz, but also by the image processor and the smoothing system. It is thanks to this that we can adjust the way we display movies or sports broadcasts to our own preferences. Available are sliders for motion blur reduction and judder reduction – the first function improves the sharpness of fast movements, while the second allows for softening the "jumping" image effect during camera pans. Therefore, everyone can choose between a cinematic character of motion and a smoother, more "television-like" style.

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.

Samsung The Frame Pro doesn’t pretend to be just a “living room” television; here, gamers will also find something for themselves. The manufacturer has ensured a full suite of gaming features: we have support for variable refresh rate (VRR), automatic 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 any downsides? Yes, The Frame Pro doesn’t support Dolby Vision in gaming mode, but it's hard to consider this a serious issue – most gamers use HDR10 anyway... so, the HGIG mode. Exactly. The biggest surprise turned out to be 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 has no ability to enable settings designed for consoles. This is a step backward that may disappoint more informed gamers expecting full compliance with HGiG guidelines. We just hope that this mistake will be quickly corrected.

Interestingly, The Frame Pro also features an atypical arrangement of HDMI 2.1 ports. We have as many as five available – four are located in the One Connect module, and the fifth, in micro HDMI version, is directly on the TV. This solution is quite unconventional, but very practical. Samsung clearly suggests that this is the port to connect your console or computer. Why? Because it minimizes potential delays associated with communication through the wireless One Connect, and in gaming, every millisecond matters. We wrote separately about input lag, but it can be revealed here that by connecting equipment directly to the TV, we achieve the absolute maximum response speed.
