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

The luminance chart for Philips PUS8959 shows that the television is capable of achieving around 550 nits of brightness, which can be considered a satisfactory level. This brightness allows for the effects of HDR to be experienced, particularly standing out in more demanding scenes. In the tested test patterns, the television performed quite well, even in challenging sequences such as 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 expense of the silvery blacks mentioned in the paragraph about black levels. It is also worth praising Philips PUS8959 for its good coverage of the DCI-P3 colour palette, which amounts to approximately 94.5%. As a result, 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.

And what about HDR? Here, the C6KS performs quite well and – as has become a recurring theme of 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 keep in mind 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 blacks. This is quite a reasonable compromise. Most viewers will definitely appreciate deep, "true black" more than additional micro-details, the display of which could cause the screen to appear greyed out. This is the nature of local dimming technology in this price range, and one must be aware of it. It is also worth noting that the TCL C69KS (C6KS) has an additional PFS coating, which is marketed under the slogan of QLED technology. Thanks to this, the colours are saturated and vibrant – our measurements showed that the coverage of a wide colour gamut reaches as much as 92% here.

The television Philips PUS8959 has been tested in the best, theoretically most precise picture mode – Filmmaker. Although the name suggests cinematic quality, it unfortunately falls short of perfection. The biggest problem in this mode is the white balance, both in HD and 4K content. It is characterised by a significant dominance of red colour and drops in green levels, resulting in unnatural colour reproduction. For example, white elements in the image have a noticeable pink hue, and the green is less vibrant, causing the overall image to lose its naturalness and colour balance. The ColorChecker test confirms these errors – it is clearly visible how the colour samples "deviate" from the correct values, which can be best observed on the sample squares that should accurately 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 chart resembles a true 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 overall appearance lack dynamism. Similar problems can be observed in the EOTF characteristics – the television is unable to accurately reproduce brightness levels, negatively impacting the overall picture quality.

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

After calibration, the television 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 considered a remarkable result. Additionally, the gamma, 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.

As for 4K HDR materials, a significant improvement is also visible. The white balance, although not as perfect as with HD content, no longer exhibits issues with excessive red exposure, resulting in a more natural and harmonious image. Unfortunately, regarding the EOTF characteristic, it is difficult to speak of any significant improvement, which stems from the structural limitations of the television that prevent any substantial enhancement in this aspect.

Nevertheless, the overall performance is significantly better after calibration, making the Philips PUS8959 one of those televisions where it is truly worth dedicating time to precise calibration to achieve satisfactory picture quality.

Thanks to the white balance adjustment, the C69KS's tendency to distort colours has been effectively limited, resulting in a very good final effect. After calibration, we will no longer see excessive warming of scenes in SDR or overly cool tones in HDR. However, it is worth noting the brightness characteristics. In SDR content, it is hard to have any objections – the image looks very good, especially in older films, television programmes, or materials from YouTube. It is significantly more challenging to evaluate the television's performance in HDR. Analysis of the EOTF curve suggests correct behaviour, but its practical variant reveals certain limitations. The C69KS can overly brighten the smallest elements of the frame, while at other times, it can dim the entire scene. Thus, calibration brought clear benefits in terms of colour quality, but certain limitations resulting from the local dimming operation and the way it is controlled by the C69KS cannot be overlooked, as we also saw in the C6K test.

When it comes to smoothing tonal transitions, the "Distortion Reduction" function at its minimum setting performs quite well, effectively smoothing tonal transitions without excessive impact 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 its place, which is a significant plus for users who appreciate the natural look of film materials.

As for digital processing, the image looks quite good, although it features very softened contours, giving it an almost "misty" character. This effect can 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 said that the Philips PUS8959 provides fairly subtle yet effective tools for improving tonal transitions without excessive interference in the natural character of the image.

The C69KS handles upscaling quite well. The tested 576p material looks surprisingly decent – a considerable amount of detail is retained, and the algorithm adds a slight "rounding" effect to sharp edges, making the image appear more cohesive. The performance in smoothing tonal transitions is less impressive. The television practically cannot improve them, leaving the image in a rather raw state. With older material, this can be quite tiring, as the lack of additional processing highlights any imperfections.

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 television offers an additional motion smoother that allows adjusting the film's 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 is responsible for increasing the number of frames through interpolation, making the motion on the screen smoother, resembling the effect of so-called "soap opera." Meanwhile, "Motion Blur Reduction" focuses on minimising ghosting and improving motion clarity, which is particularly noticeable in dynamic sequences, such as action scenes or fast-paced sports shots.

C69KS offers a simplified motion enhancement panel in films, allowing the adjustment of effect intensity with a slider. This makes it easy to match fluidity to personal preferences. The ability to use higher refresh rates is also a plus – although the panel operates natively at 4K at 60 Hz, lowering the resolution to 1440p enables 120 and 144 Hz modes, both on consoles and PC. This sounds like great news, however, in practice, the image at these settings exhibits significant motion blur. The effect is so pronounced that the overall presentation appears merely average and loses its appeal for 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 reproduction of HDR effects in games. As a result, the image is closer to what the game creators intended to achieve.

The television also supports displaying images at 120 Hz, ensuring smoothness and dynamism, which is especially important during action games and sports broadcasts. The Game Bar feature allows for 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, providing good image quality and adequate smoothness during gameplay.

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