Philips The One (PUS8959 / PUS8919 / PUS8909 / PUS8949 vs Philips OLED811

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.

Philips OLED811 uses a new generation of WOLED EX panels, also found in models such as the LG C6 and Samsung S90H. After calibration we measured around 1500 nits, which is a very good result for an OLED TV. You can see this clearly in films and series. All kinds of bright flashes have the right intensity, especially when they appear against a dark background. In such scenes the OLED811 can deliver truly impressive HDR. Of course, that does not mean you will see that level of brightness in every shot. When the screen is filled with a large amount of white or a wide explosion, brightness falls to around 600 nits. That is still a good result, but those scenes no longer have the same punch as small, bright elements on a dark background. This is a known limitation of OLEDs and the OLED811 is no exception.

Colours

Aside from HDR brightness, colours also matter and here Philips performs very well. It covers almost the entire DCI-P3 gamut, which contains most of the colours used in HDR films and series. You get saturated reds and lush greens, and when watching it’s hard to find major faults in that respect. It looks a little worse with the much wider BT.2020 gamut, whose most saturated shades are already out of reach for this panel. There is also the issue of the white subpixel that the WOLED panel uses to boost brightness. With very bright colours you can see a certain washout: the colour is bright but loses some of its intensity. It is precisely in such situations that QD-OLED panels from Samsung Display have the advantage. However, in most films and series this is not something that will immediately stand out.

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.

Film mode on the Philips OLED811 is sensibly set up straight out of the box. Most colour errors remain small, both in SDR and HDR, so you can sit down to watch without adjusting the settings first. There are no major inaccuracies that would immediately distract from the film. It falls a little short of perfection, though. The white balance shows a slight lack of red compared with green, so whites and greys can have a faint greenish tint. It is not a strong colour cast, but measurements clearly show it. There are also minor brightness deviations in SDR: some parts of the image are slightly brightened, and the darkest shades are not always reproduced evenly. In HDR the TV sticks much closer to the reference, although in places it gently lifts detail from the shadows. These are generally areas that could be improved. The factory film mode provides a good starting point, and calibration will reveal how much more can be gained from it.

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.

After calibration the Philips OLED811 produces an image very close to the reference. We managed to correct the white balance and eliminate the slight tint visible in the factory settings. Errors in the Color Checker measurements for SDR and HDR fell to around 1 to 2, and many samples are even below 1. That's a level at which differences from the reference image are hard to spot with the naked eye. We also improved the gamma, and only in the brightest whites is there a slight brightening remaining. In HDR the EOTF curve also tracks the reference closely, although the TV still tends to gently boost the brightness of small elements, such as stars or on-screen text. This gives the picture a little extra sparkle that shouldn't be there, but otherwise there's little to fault. It was already good out of the box, and after calibration we managed to refine most of the remaining shortcomings.

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.

OLED811 handles lower-quality material reasonably well, though it falls well short of perfection. The "Banding reduction" function helps to smooth tonal transitions and on the low setting gives a fairly good result. It does not remove bands between shades as effectively as similar solutions from some competitors, but at least it does not introduce new artefacts in the process. This is a sensible setting for everyday viewing. There is still some dissatisfaction, however, because the MediaTek Pentonic 800 chipset used here can, in other manufacturers' implementations, cope with the effects of heavy compression more effectively even at similarly low settings. Much therefore depends on how a given manufacturer makes use of its capabilities. We have a few more comments about the upscaling to 4K. There is a lot of detail, but the overall image looks rather soft. Edges are heavily smoothed, which robs the picture of a bit of sharpness and clarity. This can be partly corrected with the sharpness slider in the menu, though that will merely accentuate outlines rather than recover detail. On the plus side, there is no overscan; even with an SD signal the TV does not crop the edges of the picture.

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.

In terms of motion handling the OLED811 performs excellently. At 120 Hz, which is useful for console gaming and watching sport, the picture stays clear and moving objects do not leave noticeable smears. The fast response of OLED pixels helps here; this is clear in the UFO test, even on dark backgrounds. There are also motion smoothing controls. For films you can adjust the level of smoothing to suit your taste, ranging from preserving a cinematic character to much smoother motion. A separate blur reduction setting is useful for fast-paced material such as sports broadcasts.

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.

OLED811 has almost everything you could expect from a TV for gaming. It supports 120 Hz at Full HD, 1440p and 4K, and when connected to a PC it can reach 165 Hz. It also has VRR, which helps prevent screen tearing when frame rates fluctuate, and ALLM, which automatically switches to game mode. So you don't have to dig into the settings every time you power up your console.

Another plus is that HGiG works correctly, so once HDR is set on the console the TV doesn't apply its own changes to image brightness. There's also a Game Bar to check signal parameters and quickly change settings useful while gaming. The list even includes Dolby Vision for gaming, but there is a significant catch, which you can read about below.
