Philips PUS7000 vs TCL C8L / QM8L

Unfortunately, the PUS7000 is not suitable for watching HDR content. This screen is simply too dark. A brightness level of 200 nits is not enough to correctly display such a format. Even if a HDR signal message appears on the screen, the image will resemble a regular SDR recording. Therefore, it's better to stick with the latter format to avoid issues in displaying bright scenes, which you can read about below. The situation is not improved by the fact that this is a classic LCD model without additional layers to enhance colors, such as QLED or PFS. As a result, colors in HDR may appear washed out. Ultimately, this gives a worse effect than in the standard SDR format, which is simply better suited to the capabilities of this panel.

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 television in movie mode, which theoretically should provide the best and most natural colors. And indeed, this mode is quite correct; however, after connecting the calibration equipment, its biggest flaw became apparent. The PUS7000 has significant deficiencies in displaying red. Poorly tuned white balance and too low saturation of this color cause the image to appear too cool. As a result, one might get the impression that the displayed content is simply lacking in vibrant colors. The situation is exacerbated by the fact that both SDR and HDR content are excessively brightened. This is confirmed by the gamma curve and EOTF graphs, which show that the television displays the image brighter than it should. This causes scenes to lose their depth and may appear somewhat washed out. Fortunately, the Philips menu offers many functions to improve these aspects, so we immediately proceeded to calibration to see what could be squeezed out of this screen.

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.

After professional calibration, it is clear that the PUS7000 responds well to image adjustments. In this price range, this is not a given. The effects should be assessed in two scenarios, depending on what content we plan to watch. SDR performs the best. After our corrections, the image looks really good. Most color errors fell below level 3, which is the threshold at which distortions typically become visible to the naked eye in measurements. Movies, series, sports, and regular television present themselves naturally, without unpleasant deviations. If someone primarily watches classic channels or streaming in HD quality, the difference after calibration will be noticeable immediately. However, it must be made clear that the PUS7000 is still not a television suitable for sensible HDR, and calibration does not change much here. The reason lies in the hardware: colors remain too undersaturated. The television lacks solutions that expand the color gamut, such as PFS filters or a quantum dot layer, so the panel simply cannot show the intense colors required by HDR. This is most evident in reds, which still look pale. This limitation cannot be bypassed with menu settings, as it results from the design of the backlighting and the panel itself.

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.

The PUS7000 handles digital image processing quite well. The distortion reduction feature deserves praise, as it effectively smooths out unwanted tonal transitions even at a low setting. However, it has a flaw: if the action is too aggressive, it can introduce undesirable artifacts on the screen. It’s a good idea to experiment with this setting to find the sweet spot between a smooth image and detail clarity.

The upscaling, which is the enhancement of lower quality materials to 4K, is adequate. The image after processing is very "soft," which is typical for almost all Philips televisions. The edges are plastic and smooth, making the image look cohesive. If someone finds it too soft, it can always be adjusted with the sharpness slider in the menu to achieve a more pronounced effect.

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.

In this regard, we don't really have any good news. It might seem that the biggest downside is the lack of a 120 Hz panel, but in this price range, that's actually standard, and it's hard to expect more. However, the worst part is that the TV does not have any motion smoothing features. There are no supporting systems for either movies or sports. We have to accept that the image on the PUS7000 is processed "raw." This means that during dynamic scenes or fast camera movements, the motion may appear choppy or unclear. We have no way to enable any smoother that would soften this effect.

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 PUS7000 is not marketed as a gaming TV, it does not perform as poorly in this category as one might expect. While there is no support for 120 Hz refresh rates, which is understandable at this price point, the manufacturer has included several important features that genuinely improve the comfort of playing on a console. The most significant of these are VRR and ALLM technologies. VRR is responsible for synchronizing the screen with the number of frames generated by the console. This prevents the image from "tearing" and keeps it consistent even during sudden frame drops in the game. In turn, ALLM is a solution that automatically switches the TV to the lowest latency mode right after detecting a signal from the console. All of these parameters are easily accessible thanks to the Game Bar feature. This is a special control panel for gamers that can be brought up on the screen at any time. It allows for a quick overview of current settings and connection status without interrupting gameplay, which is a very convenient solution.

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.
