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

The luminance chart for Philips PUS8959 shows that the television can achieve around 550 nits of brightness, which can be considered a satisfactory level. This brightness allows the effects of HDR to be felt, particularly standing out 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 with the full "power" of the television but at the cost of the silverish blacks we mentioned in the paragraph about blacks. It is also worth praising Philips PUS8959 for its good coverage of the DCI-P3 color palette, which amounts to around 94.5%. This makes the colors vivid and close to the creators' intentions, further enhancing the quality of HDR effects and the viewing experience of high dynamic range content.

TCL C6K is a moderately bright TV that can showcase its full potential under the best cinematic conditions – the maximum brightness is around 600 nits. In scenes with large, intense light sources, the HDR effect can be really satisfying, providing a sense of cinematic brilliance. However, it should be noted that when managing the backlighting zones, there are situations where some elements become dimmed and sometimes can even become barely visible. It is clear that there is a lack of proper algorithm optimization here, although looking at the technical parameters in this price range, the design itself performs very well.

The Philips PUS8959 television was tested in the best, theoretically most precise picture mode – Filmmaker. Although the name suggests cinematic quality, it unfortunately falls far short of the ideal. The biggest issue in this mode is white balance, both in HD and 4K content. It is characterized by a significant dominance of the red color and dips in the green level, resulting in an unnatural color reproduction. For example, white elements of the image have a distinctly pinkish hue, and the green is less intense, causing the overall image to lose its naturalness and color balance. The ColorChecker test confirms these errors – it is clearly visible how the color samples "deviate" from the correct values, which can be best observed on the sample squares that should accurately reproduce colors. The lack of accuracy in this regard affects the realism and fidelity of the image, which is particularly undesirable in Filmmaker mode.

Regarding brightness characteristics, the gamma chart resembles a real roller coaster – with small elements displayed on the screen, the brightness is excessive, causing details to become overly highlighted. Meanwhile, at higher gamma values, the image loses contrast and becomes too dark, making the overall appearance look less dynamic. Similar issues can be noticed in the EOTF characteristics – the television is unable to correctly reproduce the brightness level, negatively affecting the overall image quality.

This year's TCL televisions feature a Filmmaker mode, and it must be admitted that it is definitely the best choice straight out of the box. This is the mode we recommend for everyday watching of movies and series. Unfortunately, as is often the case, the best doesn't mean perfect. In the case of SDR content, the image was too warm because the red was strongly emphasized 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 excess blue. Additionally, the brightness characteristic sometimes led to highlights being blown out. In practice, this resulted in quite noticeable color test inaccuracies that are hard to accept in a mode advertised as "by the creators."

After calibration, the Philips PUS8959 television shows a significant improvement in color reproduction, especially in HD content. The white balance is exceptionally even, and the Delta E error values are below 1, which can be considered an outstanding result. Additionally, the gamma, which is responsible for 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.

Regarding 4K HDR materials, a significant improvement is also noticeable. The white balance, although not as perfect as in HD content, no longer shows issues with excessive red exposure, making the image appear more natural and harmonious. Unfortunately, in the EOTF characteristics, it is difficult to speak of any significant improvement, due to the design limitations of the television that prevent significant enhancement in this aspect.

Nevertheless, the overall performance is much better after calibration, making the Philips PUS8959 one of those televisions where it is truly worth spending time on precise calibration to achieve satisfactory image quality.

Thanks to the white balance correction, it was possible to significantly reduce the C6K's tendency to distort colors, which resulted in a very good final outcome. After calibration, we will no longer 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, there are few complaints – the image looks really good, especially in older movies, TV shows, or materials from YouTube. This is much worse for HDR content. Analysis of the EOTF curve suggests that everything is fine, but in practice (EOTF in films), the limitations of the construction become apparent. The TV tends to overly brighten the smallest parts of the frame, and in other situations, it can dim the entire scene too much. The effect of calibration is therefore evident, and in terms of color, the C6K has gained quite a lot, but certain limitations arising from local dimming and, in fact, its management by the C6K simply cannot be overcome.

When it comes to smoothing tonal transitions, the "Distortion Reduction" function at the minimal setting performs quite well, effectively smoothing tonal transitions without excessive influence on other elements of the image. In tests, I did not notice that the reduction negatively affected the image structure, such as film grain or object details – everything remains in place, which is a big plus for users who appreciate the natural look of film materials.

On the other hand, regarding digital processing, the image looks quite good, although it is characterized by very softened contours, giving it an almost "misty" quality. This effect can evoke mixed feelings – some users may enjoy the fluidity and delicacy of this type of presentation, while others may find it too gentle, losing detail. It is a matter of individual preferences, but it must be admitted that the Philips PUS8959 provides quite subtle yet effective tools for improving tonal transitions without excessive interference in the natural character of the image.

The TCL C6K performs quite well in terms of scaling. Lower quality materials look acceptable, and the lack of overscan issues means that the image is displayed in full, without cropping. However, one cannot expect miracles – content of very low quality will not gain new life here, as the image processor has its limitations. On thin lines or details, the characteristic tearing is visible, which reveals the absence of advanced image enhancement algorithms. It is also a pity that the C6K lacks the feature for smoothing tonal transitions – in older films or video materials, color banding can be noticeable and may be bothersome during long viewing sessions.

Philips TV PUS8959 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 a significantly smoother image, 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 adjusting the frame rate of the film according to personal preferences. The Philips PUS8959 has a 10-step adjustment for the functions called "Smoothness" and "Motion Blur Reduction." The "Smoothness" function is responsible for increasing the number of frames through interpolation, making motion on the screen smoother, resembling the effect of so-called "soap opera." Meanwhile, "Motion Blur Reduction" focuses on minimizing blurring and improving motion sharpness, which is particularly noticeable in dynamic sequences, such as action scenes or fast sports shots.

TCL C6K features a 144 Hz panel, which is a significant advantage in this price range. This is an important step forward compared to the previous model C655 PRO, which offered only 60 Hz at 4K. The difference is especially noticeable when watching sports or playing games – the ball, athletes, or fast action in a game are displayed more clearly and without losing details. An interesting fact is also the ability of the panel to operate at 240 Hz, which the manufacturer does not mention in official materials. We will return to this topic when discussing the game mode for PC.

TCL also added a feature for movie watchers: "Motion Clarity," which allows you to adjust the image to your preferences using two simple sliders. You can keep the movie frame visible or opt for a very smooth, almost theatrical effect. This way, everyone can find settings tailored to their taste.

Philips PUS8959 is a television that will certainly satisfy gaming enthusiasts. It supports most modern technologies useful during gameplay, such as HGiG, allowing for better HDR effect reproduction in games. As a result, the image is closer to what the game developers intended to achieve.

The television also supports 120 Hz image display, ensuring smoothness and dynamism, which is 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 appropriate smoothness during gameplay.

The TCL C6K is a TV that can confidently be called equipment designed for gamers. Here we have 4K at 144 Hz, VRR support, automatic game mode (ALLM), and Dolby Vision Gaming. Additionally, there's a practical Game Bar, a panel with the most important settings readily available – useful when we want to quickly change something during gameplay (e.g., screen aspect ratio: Yes, that’s possible!). The wide VRR range, reaching up to 240 Hz, deserves attention. However, this is mainly an option for PC gamers who drop below the native 4K resolution. Then the TV can spread its wings and show additional smoothness, especially in fast-paced e-sports titles. In the case of consoles, we stick to the classic limit of 120 Hz, but the possibilities are still quite broad. The only drawback is a slight ghosting that can sometimes be seen in dynamic scenes. Other than that, the C6K offers everything gamers expect from a TV.
