PHILIPS PUS9010 (IPS) vs Samsung S90H (QD-OLED)

In the Philips PUS9010 version with an IPS panel, the HDR brightness unfortunately performs worse than in the previously tested 55-inch model with a VA panel. The difference reaches about 100 nits, which is quite noticeable given the relatively low values. While the VA version could exceed 500 nits, here the maximum brightness is around 400 nits. This level still allows for watching movies and series in HDR, especially on streaming platforms, but the effects are clearly muted. Bright elements do not have the same impact, and scenes requiring high luminance appear less impressive. On the positive side, the coverage of the DCI-P3 colour gamut is commendable. The IPS version offers around 91%, which is about 5% more than the variant with a VA panel. This translates to somewhat better colour saturation in HDR content, despite the lower brightness. Colours can appear more vibrant and cohesive, especially in colourful scenes.

The Samsung S90H is a genuinely bright TV for the mid-range OLED segment. In synthetic tests its peak brightness reached around 1650 nits. That’s an impressive result in this class, roughly 50% higher than what we have seen from previous models in this price bracket. Most importantly, these tests translate directly to real video material. In four out of five film clips we tested, the S90H’s brightness ranged between 1300 and 1500 nits. That headroom allows it to reproduce most HDR films with very high dynamic range and without obvious compromises, especially in material mastered to 1000–1500 nits. In practice light effects, reflections and explosions have the appropriate punch, and the picture does not appear dimmed. Of course, on full-screen very bright scenes the result is naturally lower and drops to around 900 nits. This is a direct result of the OLED panel’s protection systems working to prevent overload. Even in this scenario there is little to complain about. Those 900 nits across the whole screen is still a very high level, ensuring excellent dynamic range in HDR content.

Colour has always been a major strength of QD-OLED TVs, and the S90H is no exception. The DCI-P3 colour space we measured reached a full 100% (actually 99.9%), while coverage of the much wider BT.2020 gamut hit about 89%. That’s an excellent result, enabling very saturated and vivid colours in HDR content. It’s worth emphasising that QD-OLED’s advantage over WOLED panels is not limited to palette coverage alone. In practice it’s mainly visible in the higher brightness of saturated colours, that is in a greater colour volume. As a result, intense reds, greens and blues in HDR look more vibrant and more striking.

We assessed the colour reproduction, as always, on the factory settings, focusing on the movie mode, which for Philips usually provides the best starting point. This is also a good moment to demonstrate how much the same TV model can vary depending on the type of panel used. Looking at the white balance, the overall tendency remains similar to the variant with the VA panel. Excessive red in the whites is still noticeable, but in the tested unit with an IPS panel, there are also deficits in the blue channel. As a result, the image has a slightly different colour character, which can be clearly seen in the comparative materials. This is a very good example illustrating why ready-made settings downloaded from the internet do not always work even within the same model.

However, returning to the assessment itself, this unit performs quite well, especially with SDR content. Colour tests show correct saturation and consistency, with no glaring errors that could interfere with everyday viewing. In HDR materials, slight deficits in reds can already be noticed, but these are not flaws that spoil the overall perception of the image. The biggest limitations do not come directly from the colours, but rather from the white and black levels. The use of an IPS panel and slightly lowered gamma results in the image being slightly boosted in brightness, and the poor black levels further affect the perceived contrast. This makes the overall picture look brighter, but at the same time it loses depth, especially during evening viewing.

The next stage of the test was to check how the S90H handles colour reproduction without any calibration. As always, we carried out the measurements in Filmmaker Mode, the best factory picture preset. And here Samsung really deserves praise. The factory tuning is at a very high level, and a few years ago this was not one of its strong points. The average colour error (Delta E) remained around 3, which is below the level at which most people can notice any inaccuracies. Only in the brightest shades of grey did the values slightly approach 4, but even then it's hard to regard this as a real problem while watching. For out-of-the-box settings, the result is simply excellent.

After calibration, the picture was brought to a truly sensible level. The overall look is coherent and natural, and when it comes to colour reproduction, it is difficult to unequivocally state whether we are dealing with a VA or IPS panel. This is a good sign, showing that the television has a solid foundation for further adjustments. It is worth noting the larger colour gamut coverage in this variant, which can subtly enhance the perception of colourful scenes, particularly in HDR content. However, this advantage is largely balanced out by the boosted black levels resulting from the use of an IPS panel. The limited black depth affects the perceived contrast, especially when watching in a dark room. Consequently, despite the noticeable improvement after calibration, the final assessment remains the same as in the variant with the VA panel. Better colours are unable to fully compensate for the weaker black levels.

All right, but you know we wouldn't be ourselves if we didn't also check how far we could push the S90H after professional calibration. And there was no big surprise. Since the factory settings were already very good, there wasn't much room for improvement. Even so, we managed to refine the picture to near perfection. After calibration the mean colour reproduction errors fell below the threshold of perception, with Delta E values under 2 for both SDR and HDR material. We also improved the brightness response, so the image more faithfully reflects the creators' intent and maintains appropriate tonality across the whole luminance range. After professional calibration the S90H therefore becomes a display very close to reference.

Will the difference be spectacular for everyone? Not necessarily. The factory settings already deliver a very high level, so in everyday viewing some people may not notice a dramatic jump. Much also depends on the individual unit. Our sample was very well tuned straight out of the box, but that doesn't mean every S90H will perform at the same level. Even identical models can differ from each other in terms of factory calibration. That's exactly why professional calibration makes sense: it allows a specific unit to be brought to the highest possible accuracy, rather than relying on a bit of luck when buying.

In the Philips PUS9010, we find another iteration of the P5 Perfect Picture image processor, designed to improve the quality of inferior materials. One of the components of this system is the distortion reduction function, which is responsible for smoothing tonal transitions. It works effectively and indeed reduces the visible colour gradation. Unfortunately, it does so quite aggressively. In practice, it can dim details such as the texture of materials or film grain. This is a notable compromise, so we would not recommend it for movie screenings. However, it performs significantly better with more casual content like YouTube or regular television. The P5 processor also manages quite well with lower resolution materials. The image is soft, at times even too soft, but this can easily be corrected with the sharpness slider, adjusting the effect to personal preference. A positive aspect is also the lack of edge trimming in SD materials, which is still not standard in this class of televisions.

In this respect Samsung has changed practically nothing compared with last year’s model, which is actually quite good news. The feature responsible for smoothing tonal transitions still very effectively limits the posterisation effect. However, you should remember that it works rather aggressively, because besides the artefacts themselves it can also remove film grain and slightly soften fine image detail. As always, this is therefore a matter of compromise and personal preference. If you want the most faithful reproduction of the source material possible, we recommend leaving this function turned off.

There is also little to be said about upscaling in terms of revolution. The S90H uses the same proprietary NQ4 Gen3 image processor as its predecessor, so scaling quality has remained practically unchanged. The TV handles lower-resolution material well, effectively improving its sharpness. However, the overscan problem has still not been solved. With some older material, especially archival recordings, it may happen that a portion of the image at the edges is cropped. It’s a minor flaw, but a shame Samsung has left this issue unchanged for another year running.

Philips PUS9010 has a 4K panel with a refresh rate of 144 Hz, which will be appreciated primarily by sports fans and gamers. This is especially evident in dynamic scenes where the motion is sharp, and annoying blur is almost non-existent. When it comes to movies (standard 24 fps), Philips gives us a proven set of settings known from higher series. Two sliders are used to control motion. “Smoothness” allows you to adjust the image to your own taste: at low settings, we maintain a cinematic character, while moving the slider to the right gives us a perfectly smooth, albeit somewhat “theatrical” effect. On the other hand, “Motion Blur Reduction” is a function designed for sports – it ensures that fast-moving objects do not lose detail and remain clear.

In terms of motion handling the S90H delivers a very high level. A new feature here is a panel with a refresh rate of up to 165 Hz, although in practice that will mainly benefit PC gamers. Films, series and sports broadcasts do not use such high refresh rates, so when watching them the difference compared with the standard 120 Hz will not be noticeable. That said, thanks to the OLED panel's lightning-fast response time motion is very clean and the picture does not suffer from the motion blur typical of many LCDs. Samsung has equipped the television with extensive motion-smoothness settings. You get two sliders: judder reduction and blur reduction, which let you easily tailor the picture's character to your own preferences. You can easily achieve a very smooth image when watching sport, but you can just as well preserve a more cinematic feel at the typical 24 frames per second. It all depends on which effect you prefer.

The Philips PUS9010 is a truly solid machine for gaming. It has everything that matters: VRR, automatic game mode (ALLM), and support for HGiG. The latter is a great feature – it allows HDR in games to be set exactly as the developers envisioned. The television handles 120 Hz refresh rates effortlessly at every popular resolution (1080p, 1440p, and 4K). Whether you connect a PS5, Xbox, or a powerful PC, everything functions stably and simply as it should. Gamers will also appreciate the Game Bar. This quick, clear menu immediately shows whether the low latency mode is active. This is especially useful when frequently switching between different consoles. The whole experience is complemented by Ambilight. Evening sessions with this backlighting take the atmosphere to a whole new level – the image seems larger, and dynamic scenes leave an even better impression. Even if someone isn’t a fan of such “gadgets”, it’s hard to deny that it’s impressive.

From the outset the Samsung S90H feels like a TV designed with gamers in mind, and it's easy to see why. The manufacturer has equipped it with almost everything you could expect from a modern gaming screen. You get as many as four full-bandwidth HDMI 2.1 ports, support for ALLM and VRR, and very high refresh rates. There's also a clear Game Bar that lets you instantly check key picture parameters or change settings without leaving the game. Another very welcome improvement is the HGiG behaviour. Last year it could cause quite a few problems, but on the S90H it works exactly as it should.

Samsung's ace up its sleeve remains its proprietary Game Motion Plus mode. The feature works similarly to the motion smoothing used for films: it improves animation smoothness in games while keeping input lag at a very reasonable level. For titles running at 30 or 60 fps, with the right settings input lag did not exceed 40 ms in our tests. That's a very good result, especially since with many manufacturers enabling similar features results in delays several times higher. Game Motion Plus does not, of course, replace Dolby Vision Gaming, as it's a completely different type of feature, but overall it's a gaming addition that many players may find more noticeable. Smoother motion in 30/60 fps games often makes a bigger difference than HDR itself (which, incidentally, is often poorly implemented in games).
