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

As we mentioned with black 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 is capable of squeezing out… 4000 nits of brightness! It sounds astronomical, but – and here, unfortunately, the pattern repeats – the numbers say one thing, and practice says another. In real movie scenes, the situation looks different. At best, when the light effects occupy a large part of the image and the local dimming algorithm does not have to think too hard about what to do with thousands of zones – the effect is really good. At that point, the C9K can reach around 1500 nits, which provides a pleasant, intense flash and can indeed make a positive impression.

The problem starts with smaller elements – such as stars in the sky, the moon, or single reflections. That’s when the proverbial cat comes out of the bag: the algorithms are not yet refined, and brightness drops to even 400–500 nits. That’s a huge difference compared to the potential 4000 nits we saw in laboratory tests. Why does this happen? Most likely, the television is trying to protect the blacks in this way and minimize the halo effect around bright objects. Unfortunately, this comes at the cost of details – some details simply vanish, 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 versus SDR. Sun reflections, lamps, and highlights have a bit more sparkle than on basic TVs, whose brightness often tops out around 300 nits. However, it’s not at a level where bright elements make a particularly strong impression. The biggest limitation remains contrast. Without local dimming, the TV raises the black level around a bright object when it brightens that object. That means there’s no clear separation between strong highlights and a dark background, and that contrast is what really shows off HDR. The PQS9000 offers more than the cheapest models, but despite decent brightness the effect stays fairly basic.

Colors

Philips deserves praise for the colors. Although the manufacturer labels this model QLED, a PFS phosphor is used here instead of quantum dots. That solution does not prevent good results, however. 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, it means the vast majority of colors used in HDR movies and series will have proper saturation. Lush greens and intense reds are not a major problem and add appeal to the picture. Limitations are easier to spot in some games and rarer content that uses the most saturated shades of the wide BT.2020 gamut. In those situations, displays with wider color coverage, such as SQD or RGB LED, can show more. In its price segment the PQS9000 has nothing to be ashamed of.

For color tests, as always, we reached for the Filmmaker mode – a new feature in TCL TVs for 2025. And while 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. On the other hand, in HDR, it went in the opposite direction: the image became excessively blue. The Colour Checker test revealed quite a few color errors 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 blow out the entire scene, giving it an unnatural, even grotesque character. It's hard to call this a "director-created" mode – because the director has certainly never seen such an image.

Unfortunately, the PQS9000’s factory picture settings for Film mode need some fine-tuning. In SDR the biggest issue is an excess of red in the white balance, which makes whites, grays, and skin tones too warm, sometimes even slightly pink. On top of that, the gamma runs below the target across most of its 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. Aside from minor deviations, the components stay close to each other, so there isn’t the pronounced tint seen 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 color gamut. Many hues deviate significantly from the reference, with errors reaching 8–9. So the good gamut coverage we praised earlier doesn’t mean the TV hits specific colors accurately. It can display a wide color range, but out of the box it doesn’t use it very precisely.

After calibration, we finally managed to tame the white balance – and it immediately translated into a more natural image. Colors finally started to look the way they should, and the overall presentation was incomparably better than in the factory settings. In other words – it’s worth taking a moment to improve this, as the gain is truly significant. The gamma responsible for managing brightness was also brought into order in SDR content, and the effect was more than satisfying. 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 dimmed the darkest parts too much. Exactly as we saw in the scene from the movie Billy Lynn. So, the color improvement after calibration makes a great impression, but brightness management in HDR remains the Achilles' heel of C9K and presents a certain technological limitation.

Calibration brought a big improvement, especially in SDR material. We managed to even out the white balance and remove the previous color cast, and the Color Checker measurements now look really very good. Colors are much closer to what should be on the screen, so with regular TV or SDR movies we can be satisfied with the result. Unfortunately HDR somewhat spoils that outcome. On one hand it's limited by the panel's capabilities, since calibration won't improve contrast or replace local dimming. On the other hand there are color errors we couldn't correct because the CMS settings, that is color management, were grayed out and inactive. For that Philips loses points with us. White balance can be fine-tuned, but without access to wide color gamut controls you can't correct colors in HDR as effectively. It's a shame, because the SDR results show the potential is there, it's just not allowed to be fully used everywhere.

Digital image processing in TCL C9K is quite mediocre. The tonal smoothing feature seems to be present, but turning it on practically changes nothing – color bands are still visible, and it can unintentionally highlight elements we would prefer to hide, such as textures of objects. Fortunately, it doesn’t remove film grain, but that’s small comfort since the effects are still poor. Therefore, it's hard to recommend using this option.

On the other hand, image scaling performs much better. Lower quality materials look quite decent – characters and backgrounds are presented clearly, although, of course, with sources at 576p, physics cannot be fooled. Sometimes, characteristic aliasing on objects appears, but that’s the fault of the source itself, not the algorithm. A plus for not having issues with overscan – the image is not artificially cropped or enlarged.

The digital image processing in the Philips PQS9000 performs well, though we have a few reservations. The "Distortion Reduction" function helps smooth tonal transitions in lower-quality material, but it works quite unevenly. It can improve a section of the picture, only to, moments later and still within the same scene, seem to lose effectiveness and reintroduce banding between shades. 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 that's the one we recommend. The 4K upscaling itself is acceptable, though the picture is very soft. Edges are heavily smoothed, which may make the image feel less crisp to some viewers. In that case, it's worth slightly increasing the sharpness in the TV's menu, as this will make edges stand out more. Don't overdo the sharpness slider, however, or you may introduce artificial halos instead of improving the picture.

Like the C8K, the C9K is also a really fast television – both figuratively and literally. It features a 4K panel with a refresh rate of 144 Hz, and at lower resolutions, the display can even ramp up to 288 Hz. This speed translates into practice – when watching sports or playing games, the image looks very smooth and clear. Additionally, in films, we get an extra motion smoother called Motion Clarity, which allows us to adjust the fluidity to our own preferences – from the cinematic "judder" frame to almost theatrical smoothness.

In terms of motion handling, the Philips PQS9000 performs outstandingly 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 you can hardly see the typical trailing smears behind moving objects. What's especially pleasing is that this also applies to darker backgrounds, where many VA panels clearly struggle. Here motion remains clear, and Philips pleasantly surprised us in that regard. To adjust how motion is displayed there is the "Motion Style" function. It includes two sliders: "Smoothness" and "Blur Reduction," which let you tailor the effect to the content you're watching and your personal preferences. Our suggested settings are shown in the photo. Treat them as a starting point and try different levels of smoothing to see which you prefer.

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 key technologies work: VRR (variable refresh rate) and ALLM (automatic low latency mode). Additionally, the manufacturer added a really intuitive Game Bar, which allows you to quickly preview the most important parameters and adjust settings without digging through the menu. Also, TCL's policy is a plus – the TV is not 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 wide freedom.

Gaming features

When it comes to gaming features, the Philips PQS9000 really has a lot to offer. Four HDMI 2.1 ports let you connect multiple devices without having to decide which one gets the full-capability port. Consoles can use 120 Hz in Full HD, 1440p and 4K, and a PC can also take advantage of 144 Hz at 4K or 240 Hz if you drop down to Full HD. There's also VRR, which matches the refresh rate to the frame rate and prevents screen tearing. Its range goes from 48–240 Hz, with the upper limit applying to Full HD mode.

ALLM is included, so the TV automatically switches into game mode, and HGiG works correctly, which is useful when setting up 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 that option is hard to enjoy because of very high latency. Apart from that caveat, the feature set is really solid.
