TCL C9K vs Philips PQS9011 / PQS9001 (The One 2026)

As we mentioned with black and contrast – the C9K makes a huge impression in synthetic tests. Our measurements showed that on a screen 10% filled with white, the television is capable of squeezing out... 4000 nits of brightness! It sounds cosmic, but – and here unfortunately the pattern repeats – the numbers say one thing, and practice another. In real film scenes, the situation looks different. In the best case, when the light effects occupy a large part of the image and the local dimming algorithm doesn't have to think too hard about what to do with thousands of zones – the result is really quite good. At that point, the C9K can reach about 1500 nits, which provides a pleasant, intense flash and can indeed make a positive impression.

The problem begins with smaller elements – such as stars in the sky, the moon, or individual reflections. That's when the proverbial cat comes out of the bag: the algorithms are not yet refined, and brightness drops even to 400–500 nits. This is a huge difference compared to the potential of 4000 nits that we saw in laboratory tests. Why does this happen? Most likely, the television tries to protect the black and minimise the halo effect around bright objects. Unfortunately, this comes at the cost of details – some of the intricate details simply disappear, and the scene loses its nature.

Philips PQS9000 is a moderately bright TV. In our HDR scenes it reached roughly 450 to just over 500 nits. That's enough to notice a difference compared with SDR. Reflections of the sun, lamps or flares have a bit more sparkle than on basic TVs, whose brightness often tops out around 300 nits. However, it is not a level at which bright elements make a particularly strong impression. The biggest limitation remains contrast. Without local dimming, when the TV brightens a bright object it also raises the black level around it. There is therefore no clear separation of strong highlights from a dark background, and it is that contrast that can show what HDR can do. The PQS9000 offers more than the cheapest models, but despite decent brightness the effect remains fairly basic.

Colours

Philips deserves praise for the colours. Although the manufacturer calls this model QLED, in reality a PFS phosphor is used here instead of quantum dots. That choice does not prevent the TV from achieving good results. On both test patterns and in measurements of film scenes we recorded about 94% coverage of DCI-P3 and 75% of BT.2020. For this class of TV that is really good. In practice this means that the vast majority of colours used in HDR films and series will have appropriate saturation. Vibrant green or intense red are not much of an issue and add appeal to the picture. Limitations are easier to notice in some games and in rarer content that use the most saturated shades of the wide BT.2020 gamut. In such situations, displays with wider colour coverage, such as SQD or RGB LED, can show more. In its price bracket, however, the PQS9000 has nothing to be ashamed of.

For colour tests, we once again reached for the Filmmaker mode – a new feature in TCL televisions for 2025. And although the direction itself is a step in the right direction, the execution leaves much to be desired. The white balance in SDR content turned out to be too warm – there was an excess of red. Conversely, in HDR, it swung in the opposite direction: the image became excessively blue. The Colour Checker test revealed quite a few colour inaccuracies that were noticeable to the naked eye. An even bigger problem turned out to be what we mentioned above – managing brightness. Regardless of whether we were watching SDR or HDR content, the image had a tendency to blow out the entire scene, giving it an unnatural, almost grotesque character. Therefore, it is hard to call this a 'director’s mode' – because the director surely has never seen such an image.

Unfortunately, the factory picture settings for Film mode on the PQS9000 need refinement. In SDR the most noticeable problem is an excess of red in the white balance, which makes whites, greys and skin tones too warm, sometimes even slightly pinkish. On top of that the gamma runs below the reference across most of the range. The TV therefore brightens midtones and highlights, making the overall image look flatter than it should.

In HDR the white balance itself is much better. Apart from minor deviations the RGB components track closely, so there is no pronounced colour cast as in SDR. However, the EOTF curve shows a slight brightening of parts of the image, and the biggest issue appears in measurements of the wide colour gamut. Many hues deviate significantly from the target, with errors reaching levels of 8–9. The good gamut coverage we praised earlier therefore does not mean the TV hits specific colours equally well. It can display a wide colour range, but out of the box it does not use it very precisely.

After calibration, we finally managed to tame the white balance – and it immediately translated into a more natural image. Colours finally started to look as they should, and the overall presentation was incomparably better than with the factory settings. In other words – it’s worth taking a moment to improve this, as the gain is really significant. The gamma responsible for managing brightness was also brought under control in SDR content, and the effect was more than satisfactory. Unfortunately, when we switched on the HDR material, the situation quickly became complicated. No matter how we set the local dimming, the television had a tendency to do what it pleased with the image – either overexposing the whole picture or dimming the darkest parts too much. Just like we saw in the scene from the film Billy Lynn. Colour-wise, the improvement after calibration makes a great impression, but managing brightness in HDR remains the Achilles' heel of the C9K and constitutes a technological limitation.

Calibration brought a significant improvement, especially in SDR material. We managed to even out the white balance and remove the previous colour cast, and the Color Checker measurements now look really very good. Colours are much closer to what should be on screen, so with ordinary TV or SDR films we can be satisfied with the outcome. Unfortunately HDR somewhat spoils that result. On the one hand it is limited by the panel itself, because calibration won't improve contrast or replace local dimming. On the other hand there remain colour errors that we couldn't correct because the CMS settings, that is the colour management controls, were greyed out and inactive. That costs Philips points with us. The white balance can be fine‑tuned, but without access to wide‑gamut adjustments it's not possible to order HDR colours equally well. It's a shame, because the SDR results show the potential is there, but we weren't allowed to make full use of it everywhere.

The digital image processing in TCL C9K is rather mediocre. The tone transition smoothing feature is supposedly present, but activating it hardly makes any difference – colour banding is still visible, and it can inadvertently highlight elements we would prefer to hide, such as textures of objects. Fortunately, it does not remove film grain, but that's scant consolation considering the effects are still poor. Thus, it's hard to recommend using this option.

On the other hand, image scaling performs significantly better. Lower quality materials look quite decent – characters and backgrounds are represented clearly, although of course, with sources like 576p, the limitations of the physics cannot be disguised. Sometimes, there's characteristic aliasing of objects, but that's due to the source itself, not the algorithm. A plus for the fact that there are no overscan issues – the image is neither artificially cropped nor enlarged.

Digital picture processing in the Philips PQS9000 performs well, though we have a few reservations. The "Distortion Reduction" function helps to smooth tonal transitions in lower-quality material, but it works rather unevenly. It can improve one part of the image, only to seem to lose its effect a moment later, still in the same scene, and show banding between shades again. A plus is that it doesn't remove film grain or fine noise, so the image retains its texture. We found the 'Medium' setting worked best and we recommend it. The upscaling to 4K itself is acceptable, although the image is very soft. Edges are heavily smoothed, which may leave some viewers feeling the picture lacks definition. In that case, it's worth slightly increasing the sharpness in the TV's menu, as this will make edges appear more defined. However, don't overdo the sharpening slider, otherwise artificial halos may appear instead of an improvement.

Similar to the C8K, the C9K is also a really fast television – both figuratively and literally. On board, we have a 4K panel with a refresh rate of 144 Hz, and at lower resolutions, the panel can even ramp up to 288 Hz. Such speed translates into practice – while watching sports or playing games, the picture looks very smooth and clear. Additionally, in films, we get an extra motion smoothing feature called Motion Clarity, which allows you to adjust the smoothness to your own preferences – from the cinematic "stuttering" of frames to nearly theatrical smoothness.

In terms of motion handling the Philips PQS9000 performs exceptionally well for an LCD TV. It's not just the 144 Hz refresh rate, but above all how quickly the panel itself responds. At 120 Hz there are virtually no typical trailing smears behind moving objects. What is particularly pleasing is that this also applies to darker scenes, where many VA panels clearly struggle. Here motion remains clear and, in this respect, Philips pleasantly surprised us.

The "Motion Styles" feature lets you adjust how motion is displayed. It includes two sliders: "Smoothness" and "Blur Reduction", allowing you to tailor the effect to the content you're watching and your own preferences. Our suggested settings are shown in the photo. Treat them as a starting point and try to find the level of smoothing that suits you best.

For gaming, the TCL C9K is a complete tool. Here we have two (out of four) HDMI 2.1 ports with full bandwidth of 48 Gbps, so all the key technologies work: VRR (Variable Refresh Rate) and ALLM (Auto Low Latency Mode). Additionally, the manufacturer has included a really intuitive Game Bar, which allows you to quickly check the most important parameters and adjust settings without rummaging through the menu. Also worth noting is TCL's policy – the television does not shy away from any HDR formats, even in game mode. Whether it's HGiG or Dolby Vision for the Xbox Series S/X console – everything works as it should, giving the player a wide range of freedom.

Gaming features

In terms of gaming features, the Philips PQS9000 has a lot to offer. Four HDMI 2.1 ports let you connect several devices without having to choose which one gets the full-capability port. Consoles can use 120 Hz at Full HD, 1440p and 4K, while a PC can also make use of 144 Hz at 4K or 240 Hz if you drop to Full HD. There's also VRR, which matches the refresh rate to the frame rate and prevents screen tearing. Its range is 48 to 240 Hz, with the upper limit applying in Full HD mode.

ALLM is present, so the TV automatically switches to game mode, and HGiG works properly, which is useful when setting HDR on a console. There's also a Game Bar for quick access to settings and signal information. The list even includes Dolby Vision gaming, but it's hard to enjoy this option because of very high input lag. Aside from that caveat, the feature set is really solid.
