Philips PUS8500 vs TCL C8L / QM8L

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.

When it comes to HDR, the TCL C8L turns out to be a hellishly bright television – and I mean that literally. On a synthetic test pattern of 5%, our measuring equipment indicated a result exceeding 4500 nits. That's an almost cosmic result, considering that reference director's monitors, which we often refer to in our materials, usually operate around 4000 nits. Does this mean the C8L breaks barriers and climbs to the technological peak of Mini-LED? Not quite. Dry synthetic tests are one thing, and real film images are another. In real, varied scenes, the C8L hits around 1600 nits at its peak. That's still a very good result, ensuring a very high level of HDR dynamics, but it's clearly lower than what the manufacturer boasts in the specifications. The trouble begins with very small bursts of light – then the brightness can drastically drop to around 600 nits. The algorithm does everything it can to maintain deep blacks and minimise halo effect, but it does so at the cost of HDR impact. This is ideal evidence that laboratory test patterns rarely correlate with what we ultimately see on the screen.

Huge applause is due for colour reproduction, all thanks to the new generation of SQD (Super Quantum Dot) quantum dots. The coverage of the DCI-P3 palette reaches 97%, but the jaw-dropping measurements come from the notoriously demanding BT.2020 space. The C8L achieves an impressive 90% in this area, placing it alongside today’s top screens that feature RGB backlighting. Importantly, unlike some screens with Micro/Mini RGB backlighting, this effect is stable regardless of the scene being displayed. Of course, it’s important to remember that content mastered for such a wide gamut in films or series is still a rarity. However, the very fact that the panel has such a "reserve of colours" deserves huge admiration.

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.

We tested the TCL C8L in the best factory mode available in the TV's menu for picture fidelity. I’m of course talking about Filmmaker Mode, which was introduced into this brand’s software relatively recently (a year ago in the K series). Thanks to it, the average user can get pretty good colour reproduction straight out of the box, although it’s certainly not perfectly tuned. Looking at the factory white balance of our unit, in both SDR and HDR content, there was a clear lack of the red component, which made the picture noticeably cooler and slightly shifted towards bluish‑green hues. The issue of brightness management is also ambiguous, as we mentioned earlier. While in SDR content the linearity of the gamma parameter is really good and consistently holds the reference value of 2.4, things are much worse in HDR. Tracking the EOTF curve clearly shows the TV’s brightness is considerably boosted across the range, which can make the final image overly bright and inconsistent with the creators’ intent, and that is in a mode that by definition should avoid this. Of course, like every unit in our lab, this one was also subjected to professional calibration, and you can find the results below.

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.

As you can see, the results of a professional calibration of the TCL C8L are genuinely promising, thanks to the extensive adjustment tools the manufacturer made available in the menu. Most importantly, we were able to fully correct the white balance, eliminating a lack of red so the image finally stopped drifting into unwanted, cool tones. After this step, errors in the ColorChecker test fell to near-reference values, regularly sitting below a Delta E threshold of 2, which is under the level noticeable to the human eye.

Since the test patterns look so perfect, you might ask: why then the lower final score in this category? The answer lies in the brightness management discussed earlier. Although the menu includes sliders that let you precisely straighten the EOTF curve on synthetic signals, when confronted with real film material (I recommend turning the EOTF filter on when watching films), it becomes clear that the TV in most scenarios still responds to HDR metadata in its own way. As a result, the image can be a touch too bright and not in line with the creators' intent, and it was precisely for this lack of repeatability with real-world films that we had to dock the C8L a few points.

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).

This year the C8 series and the higher-end models have probably received the biggest and most eagerly awaited upgrade in TCL's history, and it's to do with digital image processing. The C8L is the entry-level model in the manufacturer's line-up to be fitted with the latest flagship MediaTek Pentonic 800 chipset (shown in the menu as MT9655). It is thanks to its processing power that the feature called "Gradual Smoothing" finally works the way it should. The algorithm effectively removes unwanted posterization (ugly tonal transitions / colour banding) from the picture, doing so intelligently enough that it does not degrade the sharpness of other details.

The processor also handles upscaling lower-resolution content to 4K very well. Although judging this element can be purely academic, because the differences between today's TVs in this class are very subtle. The most important point is that TCL finally has nothing to be ashamed of compared with the competition.

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 C8L is equipped with a fast panel with a native 144 Hz refresh rate. That spec will be most appreciated by demanding PC gamers, while most users, relying on consoles or TV broadcasts, will use a steady 120 Hz. And it is at 120 Hz that the motion-processing algorithms take care of image processing for films, series and sports. In the TV's menu you'll find a "Motion Clarity" option that lets you customise the motion smoothing to your preferences. The algorithms handle both cinematic productions at 24 or 30 frames per second and fast-paced sports broadcasts at 50 or 60 frames per second, maintaining the right level of smoothness.

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.

For gamers – especially for owners of powerful PCs and multiple consoles simultaneously – the TCL C8L is a true beast. This is the first model in this manufacturer's lineup that is equipped with four full HDMI 2.1 ports with a maximum bandwidth of 48 Gbps. This is directly due to the use of the new Pentonic 800 processor, which we've mentioned before. Additionally, the TV seamlessly supports practically every gaming feature. It has an automatic game mode (ALLM) that reduces latency to minimal levels, as well as full variable refresh rate (VRR) operating in an impressive range of up to 288 Hz. It also supports standards such as G-Sync and FreeSync from Nvidia and AMD. When it comes to image display standards, there are no compromises either: the C8L offers complete support for HDR formats in gaming, including gaming Dolby Vision and the HGiG profile. We can conveniently manage all these features from a very readable gamer bar (Game Bar), which we can customise according to our own preferences. From a purely gaming perspective, the C8L really has no flaws – well, maybe apart from the previously mentioned slight ghosting. But other than that? It’s a no-nonsense machine for gamers.
