TCL C9K vs Philips PUS7000

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.

Unfortunately, the PUS7000 is not suitable for watching HDR content. This screen is simply too dark. A brightness level of 200 nits is not enough to correctly display such a format. Even if a HDR signal message appears on the screen, the image will resemble a regular SDR recording. Therefore, it's better to stick with the latter format to avoid issues in displaying bright scenes, which you can read about below. The situation is not improved by the fact that this is a classic LCD model without additional layers to enhance colors, such as QLED or PFS. As a result, colors in HDR may appear washed out. Ultimately, this gives a worse effect than in the standard SDR format, which is simply better suited to the capabilities of this panel.

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.

We tested the television in movie mode, which theoretically should provide the best and most natural colors. And indeed, this mode is quite correct; however, after connecting the calibration equipment, its biggest flaw became apparent. The PUS7000 has significant deficiencies in displaying red. Poorly tuned white balance and too low saturation of this color cause the image to appear too cool. As a result, one might get the impression that the displayed content is simply lacking in vibrant colors. The situation is exacerbated by the fact that both SDR and HDR content are excessively brightened. This is confirmed by the gamma curve and EOTF graphs, which show that the television displays the image brighter than it should. This causes scenes to lose their depth and may appear somewhat washed out. Fortunately, the Philips menu offers many functions to improve these aspects, so we immediately proceeded to calibration to see what could be squeezed out of this screen.

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.

After professional calibration, it is clear that the PUS7000 responds well to image adjustments. In this price range, this is not a given. The effects should be assessed in two scenarios, depending on what content we plan to watch. SDR performs the best. After our corrections, the image looks really good. Most color errors fell below level 3, which is the threshold at which distortions typically become visible to the naked eye in measurements. Movies, series, sports, and regular television present themselves naturally, without unpleasant deviations. If someone primarily watches classic channels or streaming in HD quality, the difference after calibration will be noticeable immediately. However, it must be made clear that the PUS7000 is still not a television suitable for sensible HDR, and calibration does not change much here. The reason lies in the hardware: colors remain too undersaturated. The television lacks solutions that expand the color gamut, such as PFS filters or a quantum dot layer, so the panel simply cannot show the intense colors required by HDR. This is most evident in reds, which still look pale. This limitation cannot be bypassed with menu settings, as it results from the design of the backlighting and the panel itself.

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 PUS7000 handles digital image processing quite well. The distortion reduction feature deserves praise, as it effectively smooths out unwanted tonal transitions even at a low setting. However, it has a flaw: if the action is too aggressive, it can introduce undesirable artifacts on the screen. It’s a good idea to experiment with this setting to find the sweet spot between a smooth image and detail clarity.

The upscaling, which is the enhancement of lower quality materials to 4K, is adequate. The image after processing is very "soft," which is typical for almost all Philips televisions. The edges are plastic and smooth, making the image look cohesive. If someone finds it too soft, it can always be adjusted with the sharpness slider in the menu to achieve a more pronounced effect.

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 this regard, we don't really have any good news. It might seem that the biggest downside is the lack of a 120 Hz panel, but in this price range, that's actually standard, and it's hard to expect more. However, the worst part is that the TV does not have any motion smoothing features. There are no supporting systems for either movies or sports. We have to accept that the image on the PUS7000 is processed "raw." This means that during dynamic scenes or fast camera movements, the motion may appear choppy or unclear. We have no way to enable any smoother that would soften this effect.

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.

Although the PUS7000 is not marketed as a gaming TV, it does not perform as poorly in this category as one might expect. While there is no support for 120 Hz refresh rates, which is understandable at this price point, the manufacturer has included several important features that genuinely improve the comfort of playing on a console. The most significant of these are VRR and ALLM technologies. VRR is responsible for synchronizing the screen with the number of frames generated by the console. This prevents the image from "tearing" and keeps it consistent even during sudden frame drops in the game. In turn, ALLM is a solution that automatically switches the TV to the lowest latency mode right after detecting a signal from the console. All of these parameters are easily accessible thanks to the Game Bar feature. This is a special control panel for gamers that can be brought up on the screen at any time. It allows for a quick overview of current settings and connection status without interrupting gameplay, which is a very convenient solution.
