Philips PML9009 / 9019 / 9059 vs TCL C9K

Philips PML9009 doesn't really operate at the highest values in HDR materials. Most effects with brightness around 550 nits won't leave us thrilled with the lighting effects, although they are quite stable, which is a plus, and a considerable difference can be felt between SDR materials. It's worth noting that we can achieve a good result only in one scenario, that is in the film "Gemini," where the flashlight as the sole light source can really shine. Why in this scene? The answer is quite simple. The scene itself doesn't have a large amount of black, and the flashlight isn't as large an object as the sun in the first and last scenes. Overall, the brightness measurement results in HDR materials aren't a solid basis for recommending this television for viewing productions that use a wide color gamut. However, it's worth mentioning that this model can cover it in a not too bad 93% degree in the case of the DCI-P3 palette.

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 best factory mode used during our tests was "Filmmaker". Here, we will examine both SDR and HDR content. The key differentiator is primarily the EOTF curve in the wide colour gamut materials and gamma in those recorded "the old way". Starting with SDR films and series and the most basic thing we can observe, which is white balance, we see a significant red colour dominance. This led to a yellow tint across the whole image, causing unnaturally looking faces and yellowed whites. This issue is also clearly visible on the "ColourChecker" palette, where all colours have shifted towards their warmer counterparts. Looking at an even more significant graph, the gamma responsible for the contrast of the image, we see considerable errors beginning right from the start. From the left, the value we measured, indicated by a combined ellipsis, clearly spiked upwards, causing complete merging of details in the darkest scenes. This state of affairs persisted up to 10% brightness on the screen, after which it dove below the reference orange line, leading to a deterioration in contrast, which, as we know, Philips PML9009 is already lacking. In HDR materials, white balance issues were very similar to those in SDR content. The discrepancy appears when checking the EOTF curve, which governs the rate of brightness increase and severely limited it, resulting in an unnaturally dark image. As for the colours themselves, there were more reasons for concern here, as the television's low luminance caused a huge disparity between the actual state and the correct one, which is perfectly visible on the error graph, often exceeding the scale.

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.

Philips PML9009, like most leading manufacturers, has been providing advanced tools for calibration processes for years. Here we find 2-point and 20-point greyscale adjustments, as well as an advanced CMS (Color Management System). The differences resulting from calibration are evident, and even someone who doesn't pay attention to image quality (although there probably aren't many like that here) will notice the positive difference. Both SDR and HDR materials have undergone quite a transformation. The former and the latter have primarily shed the ugly yellow tint resulting from the red colour dominance in white balance. As for the SDR materials and gamma, although it is not perfectly modelled and still loses dark details, the rest of it is at more than a decent level, and minor errors will not be noticeable. The colours themselves look far better, and with low deltaE errors, they are almost reference-quality. On the other hand, HDR materials, due to the unit's low luminance, have not been optimised as we would have liked. Although the white balance has been largely normalised, a slight blue tint can still be observed here and there. Fortunately, the EOTF curve turned out to be much more accessible, allowing for practically perfect geometry. Unfortunately, due to the screen's too low brightness, the colour errors remain quite high.

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.

Judging by how PML9009 Philips handled tonal transitions, the image scaling test should perform just as well. This time, we are checking the TV’s algorithms responsible for enhancing the quality of images that were recorded in lower quality. Such images can be found, for example, in various TV shows or older films. In this regard, Philips PML9009 performs quite mediocrely and drastically blurs the image. This is particularly noticeable on fine branches or the model's hair.

Let’s revisit the issue of tonal transitions, which performed remarkably well. Within the unit, we will find several levels of smoothing. Even the lowest one can effectively eliminate any jerky tonal transitions and will be suitable for the vast majority of materials. More importantly, none of the settings for this function soften the effect of film grain, which is extremely important in terms of alignment with the director's vision. However, we would like to point out that sometimes it may turn out that fine details are blurred.

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.

Philips PML9009 has been equipped with a panel that has a native refresh rate of 120 Hz. This is the essential minimum for watching all kinds of sports and is recommended for comfortable gaming in favourite titles on consoles or PCs. The manufacturer, for those who dislike the characteristic judder of footage recorded at 24 fps or those requiring a high degree of motion smoothness, such as when watching football matches, has prepared an effective system for improving the sharpness of moving images. In the dedicated tab, we will find a "Smoothness" slider responsible for eliminating judder and a "Motion Blur Reduction" setting that helps to increase the sharpness of dynamic elements. The function works very well and granularly, meaning each setting has a real impact on motion perception. With such a set, every user will find their sweet spot. In the picture, we present our choice, which is slight smoothing without the soap opera effect.

A matter directly related to motion is the response time of the pixels in the panel itself. The best in this regard are of course OLED panels, followed by units based on IPS and ADS screens, and lastly VA. Despite the generally good quality of the systems responsible for smoothening the image, the use of a VA panel carries consequences in the form of black smear behind fast-moving objects. Although in the tested television this should not occur frequently, it will be noticeable here and there.

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.

Philips PML9009, equipped with HDMI 2.1 connections with full bandwidth, supports all functions dedicated to gamers. The most basic ones, such as VRR and ALLM, are a given, but G-Sync, FreeSync, or playing in HDR Dolby Vision with low input lag are not. These features activate without any problems, and during the tests conducted, they presented no obstacles. Such preparation of the television is certainly its strong point, and it can be said that it is a unit dedicated to gamers. For more advanced users, we also mention that the PML9009 is equipped with the HGIG mode, which will be particularly felt by gamers, as there are still relatively few games that support Dolby Vision. This mode primarily allows for the adjustment of HDR effects to the capabilities of the television on a special board, to prevent dimming and burning of the image.

The television additionally implements a special menu - GameBar. This allows for editing unit settings "on the fly," meaning without having to exit the game. In it, we will also find functions such as activating a crosshair or black level correction for better visibility of opponents in shadows.

In a brief summary of this paragraph, the Philips PML9009 is a unit that will undoubtedly attract gamers' attention. Thanks to its versatility, it will allow for playing any title in the highest quality without compromises. Especially since features such as VRR, ALLM, G-Sync, FreeSync, or gameplay in HDR Dolby Vision will provide an even greater immersion in the favourite title.

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.
