Philips PUS7009 (IPS) vs TCL C8L / QM8L

In terms of HDR effect quality, PUS7009 (IPS) performs very poorly. A brightness level of 250 nits does not allow for enjoyment of HDR effects, and the image resembles a more standard SDR. There is no talk of dynamic effects or vivid bursts of light. The coverage of the DCI-P3 colour gamut is only 75%, which is decidedly insufficient. The lack of full colour coverage means that the colours are not as vibrant as they should be, resulting in a flat and unconvincing image. There are no aspects for which this model could be praised in the context of HDR.

In terms of HDR, the TCL C8L turns out to be a hellishly bright television – quite literally. On a synthetic test pattern sized at 5%, our measurement equipment indicated a result exceeding 4500 nits. This is a truly astronomical result, considering that reference monitors used by directors, 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 quite. Dry synthetic tests are one thing, while real cinematic images are another. In real, varied scenes, the C8L peaks at around 1600 nits. This is still a very good result, ensuring a very high level of HDR dynamics, but it is also clearly lower than what the manufacturer boasts in the specifications. The problems begin with very small bursts of light – at that point, brightness can drastically drop to around 600 nits. The algorithm tries at all costs to maintain deep blacks and minimise the halo effect, but this comes at the expense of HDR impact. This is perfect evidence that laboratory test patterns rarely align with what we ultimately see on the screen.

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

The television was tested in film mode, which – despite its name – does not provide accurate image display. The white balance in both 4K HDR and HD/SDR content is characterised by drops in red, causing the image to appear cooler and the colours to lose their natural warmth. The gamma brightness characteristics and the EOTF curve confirm that the television has issues maintaining appropriate brightness – it heavily boosts it, resulting in an unnaturally washed-out image. This effect can be seen in the comparisons below, where the entire image appears as if it has a milky filter applied. Additionally, the limited coverage of a wide colour gamut also does not favour quality – colour checker tests indicate significant colour variations, making it difficult to achieve faithful image reproduction.

We tested the TCL C8L in the best factory mode available in the TV’s menu for image fidelity. That’s of course Filmmaker Mode, which only arrived in this brand’s software relatively recently (a year ago in the "K" series). It allows the average user to achieve quite decent colour reproduction straight out of the box, though it is certainly not perfectly tuned. Looking at the unit’s out-of-the-box white balance — in both SDR and HDR material — the red component was clearly lacking, which made the image noticeably cooler and slightly shift towards blue‑green tints. The issue of brightness management also looks ambiguous, as we mentioned earlier. While the gamma linearity in SDR content is really good and stays steadily at the reference value of 2.4, the situation in HDR is much worse. Tracking the EOTF curve clearly shows the TV has a noticeably boosted brightness across the entire range, so the final image can be excessively bright and inconsistent with the creators’ intent, and this is in a mode that by definition should avoid that. Of course, as with every sample in our lab, we subjected this one to professional calibration, and you can find the results below.

After calibration, the picture has significantly improved, especially in terms of white balance, which is now more stable, and the shades have taken on a natural quality, eliminating the previous impression of a picture that was too cool. Calibration has brought noticeable benefits in terms of tonality – shadows and midtones are now more realistic, and the overall effect seems more harmonious. Unfortunately, hardware limitations still affect the quality of the image. The brightness characteristics remain problematic, despite our efforts, and due to the poor coverage of the DCI-P3 and BT.2020 colour gamut, delta E errors are still at a high level. Although calibration has improved some aspects, the television still does not allow for complete satisfaction.

As you can see, the results of a professional calibration of the TCL C8L are truly promising, thanks to the comprehensive calibration controls the manufacturer has provided in the menu. Above all, we managed to fully correct the white balance, eliminating the red deficiency, so the image finally stopped drifting into unwanted cool tones. After that adjustment, the errors in the ColorChecker test fell to near-reference values, consistently sitting below a Delta E threshold of 2, i.e. below the visibility threshold for the human eye.

If test patterns look so perfect, you may ask us why the final score in this category is lower. The answer lies in the brightness management described earlier. Although the menu includes sliders that let you precisely straighten the EOTF curve on synthetic signals, when faced with real film material (I recommend enabling the EOTF filter 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 picture can be slightly over-bright and not faithful to the filmmakers' intent, and it is precisely for this lack of consistency with real films that we had to take a few points off the C8L's score.

When it comes to tonal transitions in low-quality material, a feature named "Distortion Reduction" (set to "minimum") effectively improves gradation, eliminating ugly tonal transitions. However, this setting on Philips televisions is quite aggressive – while it does not blur the grain or good-quality material, it can introduce undesirable effects and blur elements that should remain sharp when the signal is poorer.

In terms of image scaling, Philips PUS7009 performs reasonably well. A significant advantage is the absence of cropped image edges, meaning no overscan, which allows for the display of the full frame without loss. The image is noticeably enhanced, making characters and backgrounds, such as the model or branches in the background, appear quite detailed and natural, even with lower quality signals. Although scaling is not perfect, as it can remove desirable details in the distance, the results are good enough to satisfy most users.

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 concerns digital picture processing. The C8L is the entry-level model in the manufacturer's line-up that has been equipped with the latest flagship chip MediaTek Pentonic 800 (listed in the menu as MT9655). It is thanks to its computing power that the feature called "Gradual Smoothing" finally works as it should. The algorithm effectively removes unwanted posterization (ugly tonal transitions / colour banding) from the image, 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 assessing this element can be largely 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 with the competition.

Philips PUS7009 does not have any motion smoothing features for films, which means we cannot choose whether the picture should be more choppy or more cinematic. These features could improve more dynamic scenes. As for motion blur, despite using a 60Hz IPS panel, the situation looks quite good. The response time between pixels is better than in versions with a VA panel, which keeps motion blur at an acceptable level and does not significantly affect the comfort of watching dynamic scenes.

The TCL C8L is equipped with a fast panel with a native refresh rate of 144 Hz. This specification will be most appreciated by demanding PC gamers, while most users, who rely on consoles or TV broadcasts, will make use of a stable 120 Hz. It is at 120 Hz that the motion-processing algorithms take care of image processing (in films, series and sports). In the TV menu you'll find a "Motion Clarity" tab that allows you to tailor the motion smoothing to your own preferences. The algorithms cope well with both cinematic productions at 24 or 30 frames per second and with fast-paced sports broadcasts at 50 or 60 frames per second, ensuring appropriate smoothness.

In terms of compatibility with consoles, Philips PUS7009 is suitable for casual gamers. Despite the use of HDMI 2.0, the television offers access to features such as ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), and Game Bar. ALLM automatically switches the television to low latency mode, allowing for quicker response times during gameplay, while VRR dynamically adjusts the refresh rate to reduce the tearing effect. Game Bar is a tool that provides quick access to game settings and real-time monitoring of parameters - although we believe it appears the weakest compared to competing Game Bars.

Unfortunately, more demanding gamers may be disappointed. The Philips PUS7009 does not support advanced HDR formats in games or high refresh rates, due to the use of a 60 Hz panel. The lack of support for these features limits the television's ability to deliver smooth and fully detailed experiences during dynamic gameplay.

For gamers – and especially for owners of powerful PCs and several consoles simultaneously – the TCL C8L is a true monster. It is the first model in this manufacturer's lineup to feature as many as four full HDMI 2.1 ports with a maximum bandwidth of 48 Gbps. This is directly attributable to the use of the new Pentonic 800 processor, which we discussed earlier. Additionally, the television seamlessly supports practically every gaming feature. We have 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. There's also talk of standards such as G-Sync or FreeSync from Nvidia and AMD. When it comes to display standards, there are no compromises either: the C8L offers complete support for HDR formats in games, including gaming Dolby Vision and the HGiG profile. We can conveniently manage all of these features from a very readable player bar (Game Bar), which we can personalise to our own preferences. From a purely gaming perspective, there's really nothing to fault the C8L on – well, maybe aside from the previously mentioned slight blurring. But other than that? It's a no-nonsense machine for gamers.
