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. This situation is, however, regularly observed in this brand, so it was not a surprise to us. The first and last scenes, featuring large elements of light, look almost phenomenal, "shining" with brightness levels of 1470 and 1820 nits respectively. Such effects will certainly cause more than one person to squint, while simultaneously feeling the extraordinary dynamism of the scene itself. You can truly feel as if you are inside the film. The situation changes dramatically when small or minor elements with high luminance surrounded by black appear on the screen. The TCL C855, in order to avoid the halo effect, significantly reduces brightness to a level of even 240 nits, which is a disappointing result, causing the film to not appear as if it was recorded in HDR. The HDR effect in the TCL C855 makes watching dynamic scenes more engaging, allowing the viewer to feel as though 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 adjusted for scenes with a large amount of detail, which enhances viewing comfort.

When it comes to the HDR effect on the PUS8560, it can fairly confidently be stated that it is very average. The panel brightness is around 350 nits, which we consider to be the absolute minimum for watching content in this format. However, this is not a result that will astonish a viewer searching for the best possible picture.

On the plus side, it is worth noting that the PUS8500 series – including the PUS8560/12 we tested – is advertised as a QLED television. And indeed, we can expect a wider colour spectrum here. This model is equipped with an additional filter (PFS), and a DCI-P3 colour coverage of around 90% should suffice for the majority of users. This filter works very similarly to quantum dots. As a result, the colours are quite well saturated. It is not an outstanding result, but it is entirely sufficient for watching films 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. Like any mode predefined by the manufacturer, it had its drawbacks that are worth correcting to achieve an image as close as possible to what the film producer intended. We will examine the colour characteristics in both SDR and HDR materials. Looking at the first, we see a noticeable dominance of green in the white balance, which, as you might imagine, resulted in an unpleasant greenish tint across the entire image. Observing the very important gamma chart, which is responsible for the image's contrast, 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 the image to be overly contrasted, merging details into a dark blob. This situation persisted for quite some time, up to 20% of the chart's value, before then dipping below the reference. This, in turn, meant a brightening of the image and a significant drop in contrast. The factory mode performed slightly better in HDR materials, as the white balance looked quite good, except for the second half, where green once again took precedence. 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 was something we could also observe in the scene from the film "Pan" in the paragraph checking the TV's HDR.

We tested the television with the best available factory settings, namely 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 noticeable tendency to a pink tint, caused by an excessive amount of red and blue in the white balance. Another issue turned out to be excessive brightness in the image, which was confirmed by both the gamma chart and the EOTF curve. This feature was responsible for loss of detail and washed-out colours in more challenging HDR scenes that we mentioned earlier. The overall result led to significant colour reproduction errors – in extreme cases, the delta E value exceeded 7, while the threshold for visible errors for the human eye is around 3. This situation can be improved with calibration, and you can read about its effects below.

TCL, like the vast majority of manufacturers, provides advanced calibration tools in its televisions. Here we find 2- and 20-point adjustments for greyscale 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. The performance with HDR materials was somewhat poorer, as the TCL C855 did not allow us to model them adequately. We were only able to slightly adjust the EOTF curve and significantly improve the colours themselves.

The Dutch manufacturer offers quite a sizable amount 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 stop appearing excessively pink. The brightness characteristic has also been partially evened out, of course, within the limits set by the television itself. The image is no longer overly exaggerated, and the overall reception after calibration is definitely better than in the factory settings of the Filmmaker mode.

One could only critique the EOTF curve characteristic, which still indicates that the image has a tendency to brighten HDR materials. Despite our efforts, the darkest parts of scenes are still sometimes too bright, and the brightest ones do not always achieve their full contrast potential. However, it must be clearly stated that we are dealing with a typically budget construction – one cannot expect reference-level reproduction 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 might expect from a well-configured movie mode. However, there are certain limitations that cannot be overcome.

Once again, we will take a look at the function of smoothing tonal transitions, but this time also at image scaling. The latter is particularly important when watching lower-quality materials, such as certain television programmes or older films. We will focus on the function responsible for tonal transitions. Interestingly, just like in the scenes of the previous test, it performed excellently and smoothed out practically all the inconsistencies; however, here it had problems. Using the menu responsible for this function, we found that no setting - even the strongest - was of any help.

Image scaling in TCL C855 is described 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 for our eyes. Even the small, fine branches do not have jagged edges, and there is no white halo around figures, which is characteristic of inferior scaling systems.

Philips PUS8560 offers a function for reducing posterization, hidden under the name "distortion reduction". And although it indeed fulfills its role by smoothing out problematic tonal transitions, it works a bit too broadly. In practice, it affects not only colourful gradients but also softens faces, the textures of clothing, and the surfaces of furniture. This compromises the authenticity of the image – especially in films where natural texture is very important. However, if someone is looking for smoothing at all costs, it's best to set this option to "Low". For cinema image enthusiasts – we definitely do not recommend it.

On the positive side, the quality of upscaling older materials is noteworthy – the PUS8560 model handles them surprisingly well. The image retains its natural softness, without artificially boosted sharpness. It is also worth mentioning that the television correctly displays content with very low resolution, avoiding issues with image edge cutting (so-called overscan).

The maximum refresh rate we can set on the TCL C855 is 144 Hz. Naturally, this is only possible by connecting the TCL C855 television to a very powerful PC. Otherwise, we will be operating at a maximum refresh rate of 120 Hz, which is recommended if we primarily want to watch sports or content with a lot of motion dynamics. For those requiring high image fluidity, the manufacturer has implemented a multi-stage motion smoother. This has been divided into two separate sliders regulating the sharpness of moving images (Motion Blur Reduction) and flicker (Flicker Reduction). Both sliders can be set in the range from 0 to 10, with each increment affecting the level of smoothing, so everyone can find their sweet spot. We present a setting that allows for slight smoothing without the soap opera effect.

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

The Philips PUS8560 is a television equipped with a panel featuring a refresh rate of 60 Hz, which immediately limits its capabilities in terms of displaying dynamic content. Watching sports or playing on a console is not particularly enjoyable. 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 us to enable a motion smoother or even a slight motion smoothing for films recorded at 24 frames per second. You can imagine the effect. The image can appear jerky, especially in shots with panoramic camera movements.

The TCL C855 television is equipped with full HDMI 2.1 connectors with a full bandwidth of 48 Gb/s. During our tests, we confirmed the seamless operation of all functions that are part of this standard. As can be seen, all checkboxes light up green, which will certainly be appreciated by gamers, both console and those using the television as a monitor for their computer. 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 a very powerful setup can send a 144 Hz signal to the C855, which this television handles effortlessly. It is also worth mentioning the implementation of the HGIG mode, which, however, due to the flaw of the “Game” mode, is overly brightened, making it difficult to configure properly on screen. Fortunately, the television performs excellently with the Dolby Vision format.

The TCL C855 is one of the first manufacturers to equip its televisions with a special GameBar, which allows for extensive setting changes on the fly, without the need to exit the game. It features functions such as an additional crosshair grid, black level correction, and settings for people with disabilities. In the picture, we can see the next generation of this solution.

In summary, the TCL C855 television will be an ideal solution for those seeking a screen for all sorts of electronic gaming. Thanks to all the features supporting such entertainment, it is incredibly engaging. It is also important to highlight the very low input lag, regardless of the selected settings, including with the HDR Dolby Vision format.

Although the Philips PUS8560 is not designed with gamers in mind, the manufacturer has decided to equip it with a few features that may prove useful when connecting a console. On board, we find automatic switching to game mode (ALLM), as well as a simple connection status information bar – the so-called Game Bar. It does not make a particularly strong 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. While this is not a wide range, in the case of less demanding games or titles with unstable frame rates, VRR can help reduce screen tearing. However, this is the only element that could be considered beyond the minimum.

It must be made clear 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 response time of the panel is not among the fastest. This model may be suitable at most for casual gamers who want to enjoy the Ambilight system.
