TCL C855 vs Philips PUS8500

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.

When it comes to HDR performance on the PUS8560, one can confidently say that it is quite average. The brightness of the panel is around 350 nits, which we consider to be the absolute minimum for viewing content in this format. However, this is not a result that will impress viewers looking for the best possible image.

On the plus side, it is worth noting that the PUS8500 series – including the PUS8560/12 we tested – is marketed as a QLED television. And indeed, we can expect a wider color gamut here. This model is equipped with an additional filter (PFS), and the coverage of the DCI-P3 color space at around 90% should be sufficient for the majority of users. This filter works very similarly to quantum dots. As a result, the colors are quite well saturated. It’s not an outstanding result, but perfectly adequate for watching movies and series on streaming platforms.

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.

We tested the TV on the best available factory settings, which is in Film/Filmmaker mode – this is the mode we recommend for everyday viewing. Unfortunately, it is not without its flaws. Both in HD and HDR content, the image had a clear tendency to appear pinkish, caused by too much red and blue in the white balance. Another problem turned out to be excessive brightness of the image, which was confirmed by both the gamma chart and the EOTF curve. This characteristic was responsible for the loss of detail and washed-out colors in more challenging HDR scenes, as we mentioned earlier. Overall, this led to quite significant color reproduction errors – in extreme cases, the delta E value exceeded 7, while the threshold of visible errors for the human eye is about 3. This situation can be improved through calibration, and you can read about its effects 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.

The Dutch manufacturer offers quite a large dose of settings in their products, so as usual, we decided to dig a little into them. The effects are immediately visible – we managed to correct the white balance, which made the image stop appearing excessively pink. The brightness characteristics were also partially balanced, of course, within the limits that the television itself allows. The image is no longer overly vibrant, and the overall reception after calibration is definitely better than in the factory settings of the Filmmaker mode.

One could only criticize the characteristics of the EOTF curve, which still indicates that the image tends to lighten materials in HDR format. Despite our efforts, the darkest parts of scenes can still be too bright, and the brightest do not always reach their full contrast potential. However, it must be clearly stated that we are dealing with a typically budget construction – you cannot expect reference-quality reproduction of HDR content from it.

Calibration definitely helped this model – it improved the balance, toned down the aggressive color scheme, and brought the image closer to what one might expect from a well-configured movie mode. However, there are certain limitations that cannot be overlooked.

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.

Philips PUS8560 offers a feature that reduces posterization, hidden under the name "distortion reduction." And while it indeed serves its purpose by smoothing problematic tonal transitions, it operates a bit too broadly. In practice, it affects not only colorful gradients but also softens faces, clothing textures, and furniture surfaces. This decreases the authenticity of the image—especially in films where natural texture is of great importance. However, if someone is looking for smoothing at all costs, it's best to set this option to "Low." For cinema image enthusiasts—definitely not recommended.

On the plus side, the quality of upscaling older materials should be noted—the PUS8560 model handles them surprisingly well. The image maintains a natural softness without artificially enhanced sharpness. It is also worth mentioning that the television correctly displays very low-resolution content, avoiding problems with cropping the edges of the image (so-called overscan).

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 Philips PUS8560 is a television equipped with a 60 Hz refresh rate panel, which already limits its capabilities for displaying dynamic content. Watching sports or playing on a console is not one of the most enjoyable experiences. The situation is further worsened by the lack of any option to improve the smoothness of films. In the menu, we won't find settings that would allow for the activation of a motion smoother or even a slight motion smoothing in films recorded at 24 frames per second. You can imagine the effect. The picture may look jerky, especially in shots with panoramic camera movements.

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.

Although the Philips PUS8560 is not designed specifically for gamers, the manufacturer decided to equip it with several features that may prove useful when connecting a console. It includes automatic switching to game mode (ALLM), as well as a simple connection status information bar – the so-called Game Bar. While it does not make a particularly strong visual impression, it serves its purpose. The presence of variable refresh rate (VRR), operating in the range of 48 to 60 Hz, might come as a surprise. While this is not a wide range, in the case of less demanding games or titles with unstable fluidity, VRR can help reduce the stuttering effect. However, this is the only element that can be considered above the minimum.

It should be clearly stated that the PUS8560 is not hardware for gamers looking for a responsive screen and full support for modern console features. It lacks HDMI 2.1 ports, the refresh rate is limited to 60 Hz, and the panel's response time is not among the fastest. This model may be suitable at most for casual gamers who want to enjoy the Ambilight system.
