TCL C855 vs Philips PUS8500

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.

When it comes to HDR performance on the PUS8560, it's safe to say that it's rather average. The brightness of the panel is around 350 nits, so we consider this to be the absolute minimum for watching content in this format. However, it’s not a result that will impress viewers looking for the best possible picture.

On the plus side, it's worth noting that the PUS8500 series – including the PUS8560/12 tested here – is marketed as a QLED television. And indeed, we can expect a wider colour gamut here. This model is equipped with an additional filter (PFS), and the DCI-P3 coverage of around 90% should suffice for most users. This filter operates very similarly to quantum dots. As a result, colours are quite well-saturated. It's not an outstanding result, but it's entirely sufficient for watching movies and series from streaming platforms.

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.

We tested the television on the best available factory settings, that 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 distinct tendency to pinkness, caused by an excess of red and blue in the white balance. Another issue turned out to be excessive brightness of the image, as confirmed by both the gamma graph and the EOTF curve. This characteristic was responsible for the loss of detail and washed-out colours in more challenging HDR scenes we mentioned earlier. All of this led to quite significant colour reproduction errors – in extreme cases, the delta E value exceeded 7, while the threshold for visibility of errors for the human eye is about 3. This situation can be improved through calibration, and you can read about its effects 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.

The Dutch manufacturer offers quite a large dose of settings in its products, so as usual, we decided to tinker with them a bit. The effects are immediately noticeable – we managed to correct the white balance, which made the image cease to appear overly pinkish. The brightness characteristics were also partially equalised, of course within the limits that the television itself allows. The picture is no longer so excessively brightened, and the overall reception after calibration is definitely better than in the factory settings of the Filmmaker mode.

You could only nitpick about the characteristics of the EOTF curve, which still indicates that the image tends to brighten HDR content. Despite our efforts, the darkest parts of the scenes can still be too bright, and the brightest ones do not always reach their full contrast potential. However, it must be clearly stated that we are dealing with a typically budget-oriented design – one cannot expect reference-quality rendering of HDR content from it.

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

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.

Philips PUS8560 offers a deinterlacing function, hidden under the name “distortion reduction”. And while it indeed serves its purpose, smoothing out problematic tonal transitions, it operates a bit too broadly. In practice, it affects not just colourful gradients but also softens faces, clothing textures, and furniture surfaces. This undermines the authenticity of the image – especially in films where natural texture is of great importance. However, if someone is looking for smoothing at any cost, it’s best to set this option to “Low”. For cinema image enthusiasts – we definitely do not recommend it.

On the plus side, the quality of scaling older materials is worth noting – the PUS8560 model handles them surprisingly well. The image retains a natural softness without artificially boosted sharpness. It’s also worth mentioning that the TV correctly displays very low-resolution content, avoiding issues with image cropping (so-called overscan).

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 Philips PUS8560 is a television equipped with a 60 Hz refresh rate panel, which already limits its capabilities for displaying dynamic content right from the start. Watching sports or playing on a console is not one of the more enjoyable experiences. The situation is further worsened by the absence of any option to improve film fluidity. In the menu, you won’t find settings that would allow for the activation of motion smoothing or even a slight motion blur for films recorded at 24 frames per second. You can imagine the effect. The image can appear choppy, especially in shots with panoramic camera movements.

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.

Although the Philips PUS8560 is not designed with gamers in mind, the manufacturer has equipped it with a few features that may prove useful when connecting a console. Onboard, we find automatic switching to game mode (ALLM), as well as a simple connection status information bar – the so-called Game Bar. It doesn't make a particularly visual impression, but it serves its purpose. The presence of variable refresh rate (VRR), operating in the range of 48 to 60 Hz, may come as a surprise. This is not a wide range, but for less demanding games or titles with unstable frame rates, VRR can help reduce the tearing effect. However, this is the only element that can be considered beyond the minimum.

It must be clearly stated that the PUS8560 is not equipment 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 at best suit people who play occasionally and want to enjoy the Ambilight system.
