Philips The One (PUS8959 / PUS8919 / PUS8909 / PUS8949 vs TCL C6K

The luminance graph for Philips PUS8959 shows that the television can achieve around 550 nits of brightness, which can be considered a satisfactory level. Such brightness allows you to feel the effects of HDR, which stand out particularly in more demanding scenes. In the tested patterns, the television performed quite well, even in challenging sequences like those from "Sicario 2". Due to the lack of local dimming, the television does not dim small bright elements, and they shine at the full "power" of the television but at the cost of silvery blacks, which we mentioned in the paragraph about black levels. It’s also worth praising Philips PUS8959 for its good coverage of the DCI-P3 colour palette, which is around 94.5%. This ensures that the colours are vivid and close to the creators' intentions, which further enhances the quality of HDR effects and the experience of watching high dynamic range content.

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 television Philips PUS8959 has been tested in the best, theoretically most precise picture mode – Filmmaker. Although the name suggests film quality, it unfortunately falls short of perfection. The biggest issue in this mode is the white balance, both in HD and 4K content. It is characterised by a significant dominance of the red colour and drops in the green levels, resulting in unnatural colour reproduction. For example, white elements of the image have a noticeable pink hue, and the green is less intense, which diminishes the overall naturalness and colour balance. The ColorChecker test confirms these errors – it is clearly visible how the colour samples "deviate" from the proper values, which can best be observed on the sample squares that should precisely reproduce the colours. The lack of accuracy in this regard affects the realism and fidelity of the image, which is particularly undesirable in Filmmaker mode.

As for the brightness characteristics, the gamma graph resembles a roller coaster – with small elements displayed on the screen, the brightness is excessive, causing details to become overly exposed. Conversely, at higher gamma values, the image loses contrast and becomes too dark, making the whole appear lacking in dynamism. Similar problems can be observed in the EOTF characteristics – the television is unable to accurately reproduce the brightness levels, negatively impacting the overall picture quality.

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”.

After calibration, the Philips PUS8959 shows a significant improvement in colour reproduction, especially in HD content. The white balance is exceptionally even, and the Delta E error values are below 1, which can be regarded as an outstanding result. Additionally, the gamma, which affects brightness in lower quality materials, performs very well, maintaining a stable level at 2.4, leading to an appropriate balance between bright and dark areas of the image.

When it comes to 4K HDR materials, there is also a noticeable improvement. The white balance, although not as perfect as in HD content, no longer suffers from excessive red exposure, making the image appear more natural and harmonious. Unfortunately, regarding the EOTF characteristic, it’s difficult to speak of any significant improvement, which stems from the structural limitations of the television that prevent substantial enhancement in this aspect.

Nevertheless, overall, it looks much better after calibration, making the Philips PUS8959 one of those televisions where it's truly worth investing time in precise calibration to achieve satisfactory image quality.

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.

When it comes to smoothing tonal transitions, the "Distortion Reduction" function in the minimum position performs quite well, effectively smoothing tonal transitions without excessive impact on other elements of the image. In testing, I did not notice that the reduction negatively affected the structure of the image, such as film grain or details of objects – everything remains in its place, which is a big plus for users who value the natural look of film material.

As for digital processing, the image looks pretty good, although it features very softened contours, giving it an almost "leafy" character. This effect may evoke mixed feelings – some users will appreciate the fluidity and delicacy of this type of presentation, while others may find it too gentle, losing detail. It is a matter of individual preference, but it must be admitted that Philips PUS8959 provides quite subtle yet effective tools for improving tonal transitions without excessive interference with the natural character of the image.

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 PUS8959 TV is equipped with a 120 Hz panel, which should satisfy more demanding users, especially those who love watching dynamic sports broadcasts or playing games. Such a high refresh rate allows for significantly smoother images, being a key aspect during dynamic scenes and fast actions.

For those who prefer watching movies, the TV offers an additional motion smoother that allows adjustment of the frame rate according to personal preferences. The Philips PUS8959 features a 10-step adjustment for functions called "Smoothness" and "Motion Blur Reduction". The "Smoothness" function increases the number of frames through interpolation, making movement on the screen smoother, reminiscent of the so-called "soap opera effect". Meanwhile, "Motion Blur Reduction" focuses on minimising streaking and improving motion clarity, which is particularly noticeable in dynamic sequences such as action scenes or fast sports shots.

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 PUS8959 is a television that will surely please gaming enthusiasts. It supports most modern technologies useful during gameplay, such as HGiG, allowing for better representation of HDR effects in games. As a result, the image is more aligned with what the game developers intended to achieve.

The television also supports displaying images at 120 Hz, ensuring smoothness and dynamism, particularly important during action games and sports broadcasts. The Game Bar feature provides quick access to game settings, making it easier to adjust the image according to user preferences without interrupting gameplay.

Unfortunately, the Dolby Vision mode does not offer low input lag, which may be noticeable during dynamic scenes. Nevertheless, thanks to the HGiG feature and high refresh rate, the Philips PUS8959 remains an attractive choice for gamers, offering good image quality and suitable smoothness during gameplay.

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.
