Philips The One (PUS8959 / PUS8919 / PUS8909 / PUS8949 vs TCL C6KS / C69KS / Q6CS

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.

And how does the issue of HDR look? Here the C6KS performs quite well and – as is becoming a recurring theme in this review – identically to the C6K model. The maximum brightness generated by this television is around 600 nits. In bright scenes, this translates to a really solid, cinematic effect, and generally, the video materials look good here. However, one must remember the specifics of the dimming algorithm in this model. When very small, bright points (e.g., stars) appear against a dark background, the television can dim them quite significantly. The goal is simple: to eliminate blooming and maintain the best possible black levels. It’s a reasonable compromise. Most viewers will definitely appreciate deep, “true black” more than additional micro-details that could cause grayness on the screen. Such is the nature of local dimming technology in this price range, and one must be aware of it. It’s also worth noting that the TCL C69KS (C6KS) has an additional PFS coating, which is marketed under the tagline of QLED technology. Thanks to this, the colors are saturated and vibrant – our measurements showed that the coverage of a wide color gamut reaches 92% here.

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.

Unlike the more expensive C6K model, the tested C6KS does not have an option labeled Filmmaker Mode in the menu. Is this a reason to cry? Absolutely not. Our tests have shown that in practice, in terms of color reproduction, the absence of this specific label makes virtually no difference. The best available Film/Cinema mode here offers nearly identical picture characteristics to the aforementioned Filmmaker mode in the more expensive model. So we get a very similar image, just under a different name. So if you were wondering whether paying extra for the C6K gives you better colors – the answer is: no, in both cases the base is the same and requires slight adjustments.

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 adjustment, the tendency of the C69KS to distort colors has been effectively reduced, leading to a very good final effect. After calibration, we won't see excessive warmth in SDR scenes or overly cool tones in HDR. However, it's worth noting the brightness characteristic. In SDR content, there are hardly any objections – the image looks very good, especially in older films, television programs, or materials from YouTube. It is much more difficult to evaluate the performance of the television in HDR. Analysis of the EOTF curve suggests correct behavior, but its practical variant shows certain limitations. The C69KS can overly brighten the smallest elements of the frame, while at other times it can dim the entire scene. Calibration has therefore brought clear benefits in terms of color reproduction, but certain limitations arising from the operation of local dimming and the way it is controlled by the C69KS cannot be avoided, as we also saw in the C6K test.

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.

C69KS handles upscaling quite well. The tested 576p material looks surprisingly decent – a significant amount of detail is preserved, and the algorithm adds a subtle "rounding" effect to sharp edges, making the image appear more cohesive. However, the smoothing of tonal transitions is lacking. The television practically cannot improve them, leaving the image in a somewhat raw state. With older materials, this can be simply exhausting, as the lack of additional processing highlights all imperfections.

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.

C69KS offers a simplified motion improvement panel in movies, allowing you to adjust the intensity of the effect using a slider. This makes it easy to match the smoothness to your own preferences. The possibility of using higher refresh rates is also a plus – even though the panel operates natively at 4K at 60 Hz, lowering the resolution to 1440p allows you to enable 120 and 144 Hz modes, both on consoles and PC. This sounds like great news, but in practice, the image at these settings suffers from significant motion blur. The effect is noticeable enough that the overall experience feels simply mediocre and loses its appeal in everyday use.

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.

If we overlook the smearing and lack of native 4K at 120 Hz, the C69KS impresses with how well it performs during gaming. We get everything you can expect from a gaming television: variable refresh rate (VRR), automatic switching to game mode (ALLM), Dolby Vision Gaming mode, and a reasonably functioning HGiG. The TV can also operate at 120 and even 144 Hz at lower resolutions, allowing for smoother gameplay on console or PC. Additionally, there is a clear Game Bar that lets you quickly glance at key settings during gaming. As a result — despite a few limitations — the C69KS can be a truly successful screen for gamers.
