Philips PUS8500 vs Samsung S90H (WOLED)

When it comes to the HDR effect on the PUS8560, it can fairly confidently be stated that it is very average. The panel brightness is around 350 nits, which we consider to be the absolute minimum for watching content in this format. However, this is not a result that will astonish a viewer searching for the best possible picture.

On the plus side, it is worth noting that the PUS8500 series – including the PUS8560/12 we tested – is advertised as a QLED television. And indeed, we can expect a wider colour spectrum here. This model is equipped with an additional filter (PFS), and a DCI-P3 colour coverage of around 90% should suffice for the majority of users. This filter works very similarly to quantum dots. As a result, the colours are quite well saturated. It is not an outstanding result, but it is entirely sufficient for watching films and series from streaming platforms.

Samsung S90H in the WOLED variant is still an exceptionally bright TV for its price bracket, although compared with the QD-OLED version it is slightly dimmer. The difference is not as significant as in last year’s F series, where the gap could reach as much as 500 nits. Here the parameters of both panels are very similar, and differences in peak brightness are only in the order of 100–150 nits. In small-area measurements the S90H on the WOLED panel easily reaches levels close to 1500 nits. Such a reserve of power allows HDR dynamics to be reproduced phenomenally; all highlights, light reflections and explosions have the necessary punch, exactly as the creators intended in the editing studio. As with most OLED displays, when a very bright scene fills the whole screen protection systems activate and brightness naturally falls to around 700 nits. It is worth emphasising that this is still an excellent result on the market. Often noticeably better than many Mini LED screens in the same segment.

Colour gamut coverage

The biggest difference between the two S90H variants lies in colour reproduction and saturation. This results directly from the different construction of the WOLED panel, which uses an additional white subpixel. As a consequence, colours at very high brightness do not reach the same intense saturation, and the volume of the wide gamut is somewhat more limited than in QD-OLED. That does not change the fact that in everyday use these differences will be hard for most viewers to spot. The DCI-P3 space we measured reaches nearly 99% on the WOLED panel, which means that in the vast majority of real film scenes both variants will present an almost identical picture. The true distance only reveals itself in rarer, exceptionally demanding productions that use the ultra-wide BT.2020 gamut. Due to the specifics of the WOLED panel’s construction, coverage of that standard is about 15% lower compared with the S90HAT with a QD-OLED panel, so the brightest, heavily lit colours in HDR may appear slightly less vivid.

We tested the television with the best available factory settings, namely in Film/Filmmaker mode – this is the mode we recommend for everyday viewing. Unfortunately, it is not without its flaws. Both in HD and HDR content, the image had a noticeable tendency to a pink tint, caused by an excessive amount of red and blue in the white balance. Another issue turned out to be excessive brightness in the image, which was confirmed by both the gamma chart and the EOTF curve. This feature was responsible for loss of detail and washed-out colours in more challenging HDR scenes that we mentioned earlier. The overall result led to significant colour reproduction errors – in extreme cases, the delta E value exceeded 7, while the threshold for visible errors for the human eye is around 3. This situation can be improved with calibration, and you can read about its effects below.

In Filmmaker mode, which we strongly recommend switching on straight out of the box, the S90H offers very good factory colour tuning. Colours are natural and faithful to the creators' intent, without the irritating oversaturation found in more aggressive presets. However, as is often the case without full calibration, no two units are identical. In our test the white balance was slightly lacking in blue, causing the image to lean a little towards warmer, yellowish tones. This was most noticeable in bright scenes, such as the snowy sequences from Star Wars. Additionally, the gamma curve was slightly low at 2.2, which produced a minor lift in shadow detail. In HDR mode the tuning was somewhat better, showing only a slight undersaturation in the red region.

The Dutch manufacturer offers quite a sizable amount of settings in its products, so as usual, we decided to tinker with them a bit. The effects are immediately noticeable – we managed to correct the white balance, which made the image stop appearing excessively pink. The brightness characteristic has also been partially evened out, of course, within the limits set by the television itself. The image is no longer overly exaggerated, and the overall reception after calibration is definitely better than in the factory settings of the Filmmaker mode.

One could only critique the EOTF curve characteristic, which still indicates that the image has a tendency to brighten HDR materials. Despite our efforts, the darkest parts of scenes are still sometimes too bright, and the brightest ones do not always achieve their full contrast potential. However, it must be clearly stated that we are dealing with a typically budget construction – one cannot expect reference-level reproduction of HDR content from it.

Calibration has definitely helped this model – it improved the balance, toned down the aggressive colour palette, and brought the image closer to what one might expect from a well-configured movie mode. However, there are certain limitations that cannot be overcome.

After a full calibration it’s fair to say the S90H in WOLED guise looks almost perfect. In SDR mode colour inaccuracies drop to ultra-low levels and Delta E values very rarely exceed 2. That’s a phenomenal result, so if you care about perfectly faithful colour reproduction it’s definitely worth considering calibration. The calibrated HDR mode also performs very well, with the white balance stabilised and earlier deviations eliminated. After professional fine-tuning it’s really hard to find anything to criticise, because the TV delivers an image with almost reference-level naturalness and three-dimensionality. The slightly lower score in this category compared with the QD-OLED variant is solely due to the aforementioned limitation in saturation in extremely bright scenes; the tuning options and colour fidelity themselves are at the highest level.

Philips PUS8560 offers a function for reducing posterization, hidden under the name "distortion reduction". And although it indeed fulfills its role by smoothing out problematic tonal transitions, it works a bit too broadly. In practice, it affects not only colourful gradients but also softens faces, the textures of clothing, and the surfaces of furniture. This compromises the authenticity of the image – especially in films where natural texture is very important. However, if someone is looking for smoothing at all costs, it's best to set this option to "Low". For cinema image enthusiasts – we definitely do not recommend it.

On the positive side, the quality of upscaling older materials is noteworthy – the PUS8560 model handles them surprisingly well. The image retains its natural softness, without artificially boosted sharpness. It is also worth mentioning that the television correctly displays content with very low resolution, avoiding issues with image edge cutting (so-called overscan).

In terms of posterisation reduction itself, Samsung has kept the solutions known from last year’s models. The dedicated gradient-smoothing function performs quite well and can effectively mask unwanted tonal banding, which is useful on a WOLED panel that is slightly more prone to banding. However, you should be aware of its aggressive behaviour. This mechanism, alongside the artefacts themselves, can clean up fine film grain and gently soften detail. Ultimately it is a matter of compromise, but if you want an absolutely faithful reproduction, it is safer to leave this option off.

Similarly, in the area of scaling it is difficult to call this a breakthrough. The S90H uses the same NQ4 Gen3 processor as its predecessor, so the upscaling quality was almost identical. The chip sharpens lower-resolution material very well, extracting a satisfying level of detail. Samsung still has not dealt with the longstanding overscan issue, though. With some older recordings or archive footage the edges of the image can be slightly cropped. It’s a minor flaw, but it’s a pity the manufacturer still hasn’t eliminated it.

The Philips PUS8560 is a television equipped with a panel featuring a refresh rate of 60 Hz, which immediately limits its capabilities in terms of displaying dynamic content. Watching sports or playing on a console is not particularly enjoyable. The situation is further worsened by the lack of any option to improve the smoothness of films. In the menu, we won't find settings that would allow us to enable a motion smoother or even a slight motion smoothing for films recorded at 24 frames per second. You can imagine the effect. The image can appear jerky, especially in shots with panoramic camera movements.

In terms of motion handling, the S90H is simply excellent. This year's panel offers a boosted refresh rate of up to 165 Hz, though in practice the benefit will mainly be for gamers connecting a high-end PC. For films, series or sports broadcasts such a high refresh rate makes no difference and the picture looks exactly the same as at the standard 120 Hz. Regardless of the source, however, the OLED panel's lightning-fast response time does its job, so motion is clean and the ghosting or smearing familiar from LCD screens simply does not occur here.

Although the Philips PUS8560 is not designed with gamers in mind, the manufacturer has decided to equip it with a few features that may prove useful when connecting a console. On board, we find automatic switching to game mode (ALLM), as well as a simple connection status information bar – the so-called Game Bar. It does not make a particularly strong visual impression, but it serves its purpose. The presence of variable refresh rate (VRR), operating in the range of 48 to 60 Hz, may come as a surprise. While this is not a wide range, in the case of less demanding games or titles with unstable frame rates, VRR can help reduce screen tearing. However, this is the only element that could be considered beyond the minimum.

It must be made clear that the PUS8560 is not equipment for gamers looking for a responsive screen and full support for modern console features. It lacks HDMI 2.1 ports, the refresh rate is limited to 60 Hz, and the response time of the panel is not among the fastest. This model may be suitable at most for casual gamers who want to enjoy the Ambilight system.

Players should feel at home with the S90H, because Samsung has left few reasons to complain in that respect. The TV has four HDMI 2.1 ports, each of which supports VRR, ALLM and high refresh rates. There’s also the Game Bar, a handy menu that lets you quickly check key parameters and change settings without leaving the game. Importantly, Samsung has also improved HGiG mode. In last year’s models it could cause problems when used with a console, but on the S90H it now works as it should. What really stands out against the competition is the Game Motion Plus feature. It’s a special motion smoothing mode for games that works best with titles running at 30 or 60 fps. Motion becomes noticeably smoother, while latency remains at a reasonable level. In our measurements it was under 50 ms, so gaming is still comfortable. That’s important, because on many TVs enabling a similar smoothing feature causes such a large increase in input lag that controls become noticeably sluggish. Samsung has managed to find a good compromise here. There’s still no Dolby Vision Gaming, but in practice Game Motion Plus may prove to be a much more useful feature.
