Philips PML9009 / 9019 / 9059 vs TCL C6K

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.

TCL C6K is a moderately bright television that can showcase its full capabilities in the best movie 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's important to remember that with local dimming management, there are situations where some elements become dimmed, and sometimes even barely visible. It is clear that there is a lack of proper optimization of the algorithms, although looking at the technical parameters in this price range, the build quality performs very well.

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.

This year's TCL televisions have introduced the Filmmaker mode, and it must be said that it is definitely the best choice right out of the box. This is the mode we recommend for everyday viewing of movies 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 prominent in the white balance. On the other hand, with HDR content, we had the opposite impression – the image became cooler than it should have been, due to an excess of blue. There is also the brightness characteristic, which at times led to overexposure. In practice, these issues combined resulted in quite noticeable errors in colour tests, which are hard to accept in a mode advertised as “by the creators”.

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.

Thanks to the white balance adjustment, we were able to significantly reduce the C6K's tendency to distort colours, which resulted in a very good end result. After calibration, we won't observe the effect of excessive warming of scenes in SDR or overly cooling the image in HDR. However, it is worth taking a closer look at the brightness characteristics. In SDR content, it's hard to have major objections – the picture looks really good, especially in older movies, TV shows, or material from YouTube. It performs significantly worse with HDR content. An analysis of the EOTF curve suggests that everything is fine, but in practice (EOTF in movies), the limitations of the construction become apparent. The television tends to excessively brighten the smallest fragments of the frame, and in other situations, it can overly dim the entire scene. The effect of calibration is therefore noticeable, and regarding colourimetry, the C6K has really gained a lot, but certain limitations resulting from local dimming and actually from its management by the C6K simply cannot be overlooked.

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.

TCL C6K performs quite well in terms of upscaling. Lower quality materials appear acceptable, and the absence of overscan issues means the image is displayed in full, without cropping. However, one cannot expect miracles – very low quality content won't come to life here, as the image processor has its limitations. On thin lines or details, there is characteristic tearing visible, which indicates a lack of advanced image enhancement algorithms. It is also a shame that the C6K lacks the function of smoothing tonal transitions – in older films or video materials, colour banding can be noticeable and may be distracting during longer viewing sessions.

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.

TCL C6K uses a 144 Hz panel, which is a significant advantage in this price range. It's an important step forward in comparison to the previous model C655 PRO, which only offered 60 Hz in 4K. The difference is especially noticeable when watching sports or playing games – the ball, players, or fast action in the game are displayed more clearly and without losing detail. An interesting fact is the panel's ability to operate at 240 Hz, which the manufacturer doesn't mention in official materials. We will return to this topic when discussing the PC gaming mode.

TCL has also added a feature for movie watchers: "Motion Clarity," which allows users to adjust the image according to their preferences with two simple sliders. You can either keep the visible film frame or opt for a very smooth, almost theatrical effect. This way, everyone can find settings that match their taste.

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.

The TCL C6K is a television that can confidently be called equipment designed for gamers. We have 4K at 144 Hz, VRR support, an automatic gaming mode (ALLM), and Dolby Vision Gaming. On top of that, there's a practical Game Bar, which is a panel with the most important settings handy – useful when we want to quickly change something during gameplay (e.g. screen ratio: Yes, you can!). Notably, it has a wide range of VRR, reaching up to 240 Hz. However, this option is mainly for PC gamers who drop below the native 4K resolution. In that case, the television can spread its wings and show additional smoothness, especially in fast e-sport titles. For consoles, we stick with the classic limit of 120 Hz, but the possibilities are still quite broad. The only slight drawback is some minor motion blur that can occasionally be seen in dynamic scenes. Other than that, the C6K offers everything gamers expect from a television.
