TCL C6K vs Philips PQS9011 / PQS9001 (The One 2026)

TCL C6K is a moderately bright television that can showcase its full potential under the best cinematic conditions – the maximum brightness is around 600 nits. In scenes with large, intense light sources, the HDR effect can be truly satisfying, providing a sense of cinematic sparkle. However, it is important to remember that when managing backlight zones, there are occasions where some elements are dimmed, and at times become barely visible. It is clear that there is a lack of proper algorithm optimisation here, although looking at the technical parameters in this price range, the overall construction performs exceedingly well.

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.

In this year's TCL televisions, the Filmmaker mode has appeared, and it must be admitted that it is definitely the best choice straight out of the box. This is the mode we recommend for daily watching of films and series. Unfortunately, as is often the case, the best does not mean perfect. In the case of SDR content, the image was too warm, as the red was quite pronounced in the white balance. Conversely, with HDR content, we had the opposite impression – the image became cooler than it should have been due to an excess of blue. Additionally, the brightness characteristics sometimes led to overexposure. In practice, this resulted in quite noticeable errors in colour tests, which are difficult to accept in a mode advertised as "from the creators."

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.

Thanks to the white balance adjustment, it was possible to significantly reduce the C6K's tendency to distort colours, which translated into a very good final result. After calibration, we will no longer observe the effect of excessive warmth in SDR scenes or overly cooling the image in HDR. However, it is worth taking a closer look at the brightness characteristics. In SDR content, it is difficult to have major objections – the image looks really good, especially in older films, television programmes, or materials from YouTube. It fares much worse in the case of HDR content. An analysis of the EOTF curve suggests that everything is fine, but in practice (EOTF in films), the limitations of the design become apparent. The television tends to over-brighten the smallest parts of the frame, and in other situations, it can dim an entire scene too much. The effect of calibration is therefore evident, and in terms of colour, the C6K has gained quite a lot, but certain limitations arising from local dimming and, in fact, from its management by the C6K simply cannot be overcome.

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.

TCL C6K performs quite well in terms of scaling. Lower quality materials look acceptable, and the absence of overscan issues means that the image is displayed in full, without cropping. However, one cannot expect miracles – very low-quality content will not gain a new life here, as the image processor has its limitations. On thin lines or details, there is a noticeable characteristic jerking, which reveals the lack of advanced image enhancement algorithms. It is also a pity that the C6K lacks the feature for smoothing tonal transitions – in older films or video materials, colour banding can be noticeable and can be distracting during longer viewing sessions.

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.

The TCL C6K utilises a 144 Hz panel, which is a significant advantage in this price range. This is an important step forward compared to the previous model, the C655 PRO, which only offered 60 Hz in 4K. The difference is especially noticeable when watching sports or gaming – the ball, players, or fast action in a game are shown more clearly and without losing details. Interestingly, the panel can also operate at 240 Hz, which the manufacturer does not mention in the official materials. We will return to this topic when discussing the PC gaming mode.

TCL has also added a feature for those watching films: "Motion Clarity", which allows users to adjust the image to their liking using two simple sliders. One can either keep the film frame visible or opt for a very smooth, almost theatrical effect. This way, everyone can find settings tailored to their taste.

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.

The TCL C6K is a television that can confidently be described as equipment designed with gamers in mind. Here we have 4K at 144 Hz, VRR support, automatic game mode (ALLM), and Dolby Vision Gaming. Additionally, there is a practical Game Bar, which is a panel with the most important settings easily accessible – useful when we want to quickly change something during gameplay (e.g. screen aspect ratio: Yes, it can be done!). The wide range of VRR is also noteworthy, reaching up to 240 Hz. However, this option is primarily for PC gamers who will drop the resolution below native 4K. At that point, the television can spread its wings and demonstrate extra fluidity, especially in fast-paced esports titles. In the case of consoles, we stick to the classic limit of 120 Hz, but the possibilities are still really broad. The only drawback might be slight ghosting, which can sometimes be seen in dynamic scenes. Apart from that, though, the C6K offers everything that gamers expect from a television.

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.
