Philips PUS7000 vs Samsung S90H (WOLED)

Unfortunately, the PUS7000 is not suitable for watching HDR content. The screen is simply too dark. A brightness level of 200 nits is insufficient to properly display such a format. Even if a HDR signal message appears on the screen, the image will resemble a standard SDR recording. Therefore, it is better to stick with the latter format to avoid errors in displaying bright scenes, as discussed below. The situation is not improved by the fact that this is a classic LCD model without additional layers enhancing colours, such as QLED or PFS. As a result, colours in HDR may appear washed out. Ultimately, this gives a worse effect than in the standard SDR format, which is simply better suited to the capabilities of this panel.

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 in movie mode, which theoretically should provide the best and most natural colours. And indeed, this mode is quite correct; however, after connecting the calibration equipment, its biggest flaw came to light. The PUS7000 has significant shortcomings in displaying red. Poorly tuned white balance and overly low saturation of this colour cause the image to appear too cool. As a result, one may get the impression that the displayed content is simply lacking in vibrant colours. The situation is worsened by the fact that both SDR and HDR content are excessively brightened. This is confirmed by the gamma curve and EOTF graphs, which show that the television displays the image brighter than it should. This causes scenes to lose their depth and may appear somewhat washed out. Fortunately, in the Philips menu, we find quite a few functions to improve these aspects, so we immediately proceeded to calibration to see what could be squeezed out of this screen.

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.

After professional calibration, it is evident that the PUS7000 responds well to image adjustments. In this price range, this is not at all a given. The effects should be evaluated in two scenarios, depending on what content we plan to watch. SDR performs the best. After our adjustments, the picture looks really good. Most colour errors have fallen below level 3, which is the threshold at which distortions usually begin to be visible to the naked eye in measurements. Films, series, sports, and regular television look natural, without unpleasant deviations. If someone mainly watches classic channels or streams in HD quality, the difference after calibration will be noticeable immediately. However, it must be clearly stated that the PUS7000 is still not a television suited for reasonable HDR, and calibration changes very little in this regard. The reason lies in the hardware: the colours remain too unsaturated. The television lacks solutions to expand the colour gamut, such as PFS filters or a quantum dot layer, so the panel simply cannot display the intense colours required by HDR. This is most apparent in reds, which still look pale. This limitation cannot be bypassed with menu settings, as it stems from the design of the backlighting and the panel itself.

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.

The PUS7000 handles digital image processing quite well. The distortion reduction feature deserves praise, as it effectively smooths out unwanted tonal transitions even at low settings. However, it has a drawback: if applied too aggressively, it can introduce undesirable artifacts on the screen. Therefore, it would be a good idea to experiment with this setting to find a happy medium between a smooth image and detail clarity.

The upscaling, or enhancing the quality of lower-resolution materials to 4K, is adequate. The image after processing is very "soft," which is typical for nearly all Philips televisions. The edges are plastic and smooth, making the image look cohesive. If it feels too soft for someone, the sharpness slider in the menu can always be adjusted to achieve a more pronounced effect.

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.

In this respect, we actually have no good news. It might seem that the biggest downside is the lack of a 120 Hz panel, but in this price range, that is actually the norm, and it is hard to expect anything more. However, the worst part is that the television does not have any features to improve motion smoothness. There is a lack of any supporting systems, both in films and in sports. We must come to terms with the fact that the image on the PUS7000 is processed "raw". This means that during dynamic scenes or fast camera movements, the motion can appear choppy or unclear. We do not have the option to enable any smoothers that would reduce this effect.

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 PUS7000 is not marketed as a gaming television, it does not perform as poorly in this category as one might expect. While it is true that we won’t find support for 120 Hz refresh rates, which is understandable at this price point, the manufacturer has ensured several important features that genuinely enhance the gaming experience on consoles. The most important of these are the VRR and ALLM technologies. VRR is responsible for synchronising the screen with the number of frames generated by the console. This prevents the image from tearing and keeps it consistent even during sudden drops in frame rate while gaming. In contrast, ALLM is a solution that automatically switches the television to the lowest latency mode as soon as it detects a signal from the console. All these parameters are easily accessible thanks to the Game Bar feature. This is a special control panel for gamers that can be summoned on screen at any time. It allows for a quick preview of the current settings and connection status without interrupting gameplay, which is a very convenient solution.

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.
