Philips PUS8500 vs TCL C8L / QM8L

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.

In terms of HDR, the TCL C8L turns out to be a hellishly bright television – and I mean literally. On a synthetic chart of 5%, our measuring equipment indicated a result exceeding 4500 nits. This is a result that is downright cosmic, considering that reference director monitors, which we often refer to in our materials, typically operate around 4000 nits. Does this mean that the C8L breaks barriers and climbs to the technological peak of Mini-LED? Not exactly. Dry synthetic tests are one thing, and real movie images are another. In real, varied scenes, the C8L achieves a peak of around 1600 nits. This is still a very good result, ensuring a very high level of HDR dynamics, but also clearly lower than what the manufacturer boasts in the specifications. The trouble starts with very small flashes of light – then brightness can drastically drop to around 600 nits. The algorithm tries at all costs to maintain deep black and minimize halo effect, but it does so at the expense of HDR impact. This is perfect evidence that laboratory charts rarely correspond to what we ultimately see on the screen.

Huge applause is due for color 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 true jaw-dropper is the measurement of the extremely demanding BT.2020 space. The C8L achieves as much as 90% in it, placing it alongside today's top screens that boast RGB backlighting. Importantly, unlike some screens with Micro/Mini RGB backlighting, this effect is stable regardless of the scene displayed. Of course, one must remember that content mastered for such a wide gamut in films or series is still a rarity. However, the mere fact that the panel has such a "color reserve" deserves immense admiration.

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.

We tested the TCL C8L in the best factory picture mode available in this TV’s menu for image fidelity. That, of course, is Filmmaker Mode, which appeared in this brand’s software relatively recently (a year ago in the "K" series). Thanks to it, an average user can get a pretty good color reproduction straight out of the box, although it is certainly not a perfectly tuned mode. Looking at the factory white balance of our unit, both in SDR and HDR material, the red component was clearly lacking, which made the image noticeably cooler and caused a slight shift toward bluish-green tints. The issue of brightness management is also ambiguous, as we mentioned earlier. While for SDR content the gamma linearity is actually correct and holds steadily at the reference value of 2.4, in HDR things look much worse. Tracking the EOTF curve clearly shows the TV has a significantly boosted brightness across the range, which can make the final image overly bright and inconsistent with the creators’ intent, and that in a mode that by definition should avoid that. Of course, like every sample in our lab, this one also underwent professional calibration, and its results are shown below.

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.

As you can see, the results of a professional calibration of the TCL C8L are really promising, thanks to the extensive adjustment tools the manufacturer put at our disposal in the menu. Above all, we were able to completely correct the white balance — we eliminated the red deficiency, so the image finally stopped drifting toward unwanted cool tones. After that adjustment, errors in the ColorChecker test fell to near-reference levels, regularly landing below a Delta E of 2, which is below the threshold of human perception.

If the test patterns look this 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 actual movie material (I recommend enabling the EOTF filter when watching movies), you can see that in most scenarios the TV still reacts to HDR metadata its own way. As a result, the picture can be slightly over-brightened and not faithful to the creators' intent, and it was precisely this lack of consistency with real films that cost the C8L a few points.

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).

This year the C8 series and higher models received probably the biggest and most anticipated upgrade in TCL’s history, and it specifically concerns digital image processing. The C8L is the lowest-end model in the manufacturer's lineup to be equipped with the latest flagship chip, the MediaTek Pentonic 800 (listed in the menu as MT9655). Thanks to its processing power, the feature called "Gradual Smoothing" finally works as it should. The algorithm effectively eliminates unwanted posterization (ugly tonal transitions/color banding), 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 evaluating this element can be mostly academic, because the differences between today's TVs in this class are very subtle. The most important takeaway is that TCL finally has nothing to be ashamed of compared to 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. 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 C8L is equipped with a fast panel that has a native 144 Hz refresh rate. That spec will be most appreciated by demanding PC gamers, while most users, who rely on consoles or TV broadcasts, will use a steady 120 Hz. It is at 120 Hz that motion processing algorithms handle image rendering for movies, series, and sports. In the TV’s menu you’ll find a "Motion Clarity" option that lets you adjust the motion smoothing to your preferences. The algorithms handle cinematic material at 24 or 30 frames per second (fps) as well as dynamic sports broadcasts at 50 or 60 fps, maintaining appropriate smoothness.

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.

For gamers – especially for those with powerful PCs and several consoles at the same time – the TCL C8L is a true beast. It’s the first model in the manufacturer’s lineup equipped with four full HDMI 2.1 ports with a maximum bandwidth of 48 Gbps. This is directly thanks to the new Pentonic 800 processor we wrote about earlier. Additionally, the TV seamlessly supports virtually every gaming feature. It has an automatic game mode (ALLM) that reduces latency to minimal levels and full frame synchronization (VRR) operating in an impressive range of up to 288 Hz. We’re also talking about standards like G-Sync or FreeSync from Nvidia and AMD. When it comes to image display standards, there are also no compromises: the C8L offers complete support for HDR formats in games, including gaming Dolby Vision and the HGiG profile. All of these features can be conveniently managed from a very readable game bar (Game Bar), which we can customize according to our preferences. From a purely gaming perspective, there really isn’t anything to complain about in the C8L – well, maybe aside from the previously mentioned slight ghosting. But other than that? It’s an unflawed machine for gamers.
