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

As we mentioned regarding black levels and contrast – the C9K can make a huge impression in synthetic tests. Our measurements showed that on a screen 10% filled with white, the television can achieve... 4000 nits of brightness! It sounds out of this world, but – and here's where the pattern unfortunately repeats – the numbers say one thing, and the practical experience says another. In real movie scenes, the situation looks different. In the best-case scenario, when light effects occupy a large part of the image and the local dimming algorithm doesn't have to ponder too much about what to do with thousands of zones, the effect is really quite good. At that point, the C9K can hit around 1500 nits, which delivers a pleasant, intense burst and can indeed leave a positive impression.

The problem arises 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 to as low as 400–500 nits. That's a huge difference from the potential 4000 nits we saw in lab tests. Why does this happen? Most likely, the television is trying to protect the black levels in this way and minimize the halo effect around bright objects. Unfortunately, this comes at the expense of detail – some details simply vanish, and the scene loses its nature.

The 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. Sun reflections, lamps or flares have a bit more punch than on basic TVs, whose brightness often tops out around 300 nits. It’s not, however, a level where bright elements look especially striking. The biggest limitation remains contrast. Without local dimming, brightening a bright object also lifts the black level around it. So there’s no clear separation between strong highlights and a dark background, and it’s that kind of pairing that really shows 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 markets this model as QLED, it actually uses a PFS phosphor instead of quantum dots. The solution itself doesn’t prevent good results. On test patterns and in measurements of film scenes we recorded about 94% DCI-P3 coverage and 75% BT.2020. For this class of TV that’s really good. In practice this means the vast majority of colours used in HDR films and series will have appropriate saturation. Lush greens or intense reds aren’t a problem and add appeal to the picture. Limitations are easier to notice in some games and rarer content that use the most saturated shades of the wide BT.2020 gamut. In those situations, displays with wider colour coverage, such as SQD or RGB LED, can show more. At its price point 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. While the direction is a step in the right way, the execution leaves a lot to be desired. The white balance in SDR content turned out to be too warm – there was an excess of red. On the other hand, 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 – brightness management. Regardless of whether we were watching SDR or HDR content, the image tended to wash out the entire scene, giving it an unnatural, almost grotesque character. Therefore, it’s hard to call this a "director's mode" – because no director has ever seen such an image.

The factory picture settings for Movie mode on the PQS9000 unfortunately need tweaking. In SDR the biggest problem is an excess of red in the white balance, which makes whites, greys and skin tones too warm, in places even slightly pink. Gamma runs below the reference across most of the range. The TV therefore brightens midtones and highlights, making the image look flatter than it should.

In HDR the white balance itself performs significantly better. Apart from minor deviations the components sit close together, so there isn’t the same obvious tint as in SDR. The EOTF curve, however, shows a slight brightening of parts of the image, and the biggest issue appears when measuring the wide colour gamut. Many shades deviate substantially from the target, with errors reaching ΔE 8–9. The good gamut coverage we praised earlier therefore doesn’t mean the TV hits specific colours accurately. It can display a wide range of colours, but out of the box it doesn’t use that range 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 on 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 brightness management also managed to be brought into order in SDR content, and the effect was more than satisfactory. Unfortunately, when we turned on HDR materials, the situation quickly became complicated. No matter how we set the local dimming, the television had a tendency to do what it liked with the image – either it overexposed everything or darkened the darkest parts too much. Just like we saw in the scene from the movie Billy Lynn. Colour-wise, the improvement after calibration makes a great impression, but brightness management in HDR remains the Achilles' heel of the C9K and presents a certain technological limitation.

Calibration brought a big improvement, especially with SDR content. We managed to even out the white balance and remove the earlier colour cast, and the Color Checker measurements now look very good. Colours are much closer to what they should be on screen, so with regular TV or SDR movies we can be happy with the result. Unfortunately HDR spoils that a bit. On the one hand it's limited by the panel itself, because calibration won't improve contrast or replace local dimming. On the other hand there are colour errors we couldn't correct because the CMS settings, i.e. colour management, were greyed out and inactive. That loses Philips points with us. The white balance can be fine-tuned, but without access to wide gamut controls you can't as effectively sort out colours in HDR. It's a shame, because the SDR results show the potential is there, but we weren't allowed to fully make use of it everywhere.

Digital image processing on the TCL C9K is rather average. The smooth tone transition feature seems to be present, but activating it practically changes nothing – colour bands are still visible, and it can unintentionally highlight elements we’d rather keep hidden, such as object textures. Fortunately, it doesn’t remove film grain, but that’s poor consolation given that the effects are still meagre. It’s therefore hard to recommend using this option.

On the other hand, image scaling presents itself much better. Lower quality materials look quite decent – characters and backgrounds are rendered clearly, although of course, with sources like 576p, the laws of physics cannot be fooled. Occasionally, there’s characteristic edge distortion of objects, but that’s the fault of the source itself, not the algorithm. A plus for not having issues with overscan – the image isn't artificially cropped or enlarged.

Digital image processing on the Philips PQS9000 performs well, although we have a few reservations. The "Distortion Reduction" function helps smooth tonal transitions in lower-quality sources, but it works rather unevenly. It can improve one part of the picture, only to, moments later and still within the same scene, lose its way and show banding between shades again. On the plus side, it doesn't strip away film grain or fine noise, so the image retains its texture. We found the "Medium" setting worked best and that's the one we recommend.

The upscaling to 4K itself is adequate, though the image is very soft. Edges are heavily smoothed, which may leave some viewers wanting more clarity. In that case, it's worth slightly increasing the sharpness in the TV menu, as this will help emphasise edges more. Don't overdo the sharpness slider, though, or you'll get artificial halos instead of an improvement.

Similar to the C8K, the C9K is also a really fast TV – both figuratively and literally. It features 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 image looks very smooth and clear. Additionally, in movies, we get an extra motion smoother called Motion Clarity, which allows you to adjust the smoothness to your own preferences – from cinematic "judder" to almost theatrical smoothness.

In terms of motion handling the Philips PQS9000 performs exceptionally well for an LCD TV. It's not just about the 144 Hz refresh rate, but above all how quickly the panel itself responds. At 120 Hz you can hardly see the typical trailing smears behind moving objects. What's particularly pleasing is that this also applies to darker backgrounds, where many VA panels clearly struggle. Here motion remains clear, and in this respect Philips has pleasantly surprised us.

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

From a gaming perspective, the TCL C9K is a complete tool. It features two (out of four) full bandwidth 48 Gbps HDMI 2.1 ports, 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 that allows you to quickly check the most important parameters and adjust settings without fumbling through menus. Also, TCL's policy is a plus – the TV isn’t afraid of 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 plenty of freedom.

Features for gamers

In terms of gaming features the Philips PQS9000 has a lot to offer. Four HDMI 2.1 ports let you connect multiple devices without having to choose which one gets the full capabilities. Consoles can use 120 Hz at Full HD, 1440p and 4K, and a PC can also run 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 runs from 48 to 240 Hz, with the upper limit applying to Full HD mode.

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