SAMSUNG S90F (WOLED) vs Philips PUS7000

Does the S90F handle not only blacks but also bright parts of the image? Definitely. The stories about OLEDs as "dark screens" can slowly be regarded as myth. The Samsung S90F, like the LG C5 based on a very similar panel, achieves brightness exceeding 1000 nits. This is a value more than enough to enjoy impressive and dynamic HDR images – both in movies and series. Most of the scenes we tested look stunning, with well-defined highlights and high contrast. Of course, OLED technology still has its limitations – in very bright, full-screen sequences, such as the test card from the movie The Meg (photo 5), the television may noticeably dim the image. However, it should be emphasized that such scenes are rare. It can be said that the HDR effect is good enough that even mid-range OLED models like the S90F can provide a cinematic experience in the home living room.

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

Samsung S90F, like most modern televisions, offers many picture modes, but – following our testing tradition – we checked it out in the best one, which is the Filmmaker mode. Thanks to this, the image looks much more natural than in the default, often oversaturated settings. It was neither overly saturated nor artificially dimmed – simply closer to what one should see. Of course, “more accurate” doesn’t mean “perfect”. Unfortunately, our S90F had significant issues with white balance, particularly in the blue color range, resulting in a slightly yellowish filter being applied to most scenes. Someone might say it looks more “filmic” – because it’s warmer – but let’s not kid ourselves, George Lucas didn’t film Star Wars in sepia 😉 (you’ll find a comparison with the scene below as always).

Additionally, in HDR materials, there was an issue with brightness management. The EOTF curve showed a clear “spike” in brightness – the television brightened the image more than it should have, causing some effects to look too intense and deviating from the reference. Fortunately, some of these problems can be eliminated through professional calibration – you’ll read about its effects later in the review.

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, when we connected the calibration equipment, its biggest flaw became apparent. The PUS7000 has significant shortcomings in displaying reds. Poorly tuned white balance and too low saturation of this colour cause the image to appear too cool. As a result, one might get the impression that the displayed content lacks 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 can make them seem slightly washed out. Fortunately, in the Philips menu, we find plenty of features to improve these aspects, so we immediately proceeded to calibration to see what we could extract from this screen.

After calibration, we managed to eliminate practically all the previously mentioned errors. Older movies in SDR quality finally look like they should – without the sepia effect or artificial aging of the image. The atmosphere of the classics is back in place (no thanks needed, Star Wars fans), and the colours no longer resemble an Instagram filter.

One of the key changes was also the improvement of brightness characteristics in HDR content. We managed to control the EOTF curve in almost a reference manner. Admittedly, the most demanding users may detect minimal deviations in brightness, but honestly – most viewers won't even notice that. And it's no surprise because the vast majority of errors fall below the ΔE 3 value, which is below the threshold of visibility. After calibration, the S90F (WOLED) becomes a truly excellent display – one on which you can enjoy nearly perfect image quality.

After professional calibration, it’s evident that the PUS7000 responds well to image adjustments. In this price range, that’s not a given. The effects are best evaluated in two scenarios, depending on the content we plan to watch. SDR performs the best. After our adjustments, the image looks really good. Most colour errors have dropped below level 3, which is the threshold at which discrepancies usually become visible to the naked eye. Movies, series, sports, and regular television present naturally, without unpleasant deviations. If someone mainly watches classic channels or streams in HD quality, the difference after calibration will be noticeable straight away. However, it must be said clearly that the PUS7000 is still not a television suited for proper HDR, and calibration doesn't change much in this regard. The reason lies in the hardware: colours remain too unsaturated. The television lacks solutions that widen 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 evident in reds, which still look washed out. This limitation cannot be circumvented through menu settings, as it stems from the design of the backlighting and the panel itself.

Digital Image Processing in S90F:

Fortunately, Samsung, like in most of its models, manages to effectively tackle the unwanted posterisation effect in the S90F. The function responsible for this element is noise reduction, which does a pretty good job of smoothing tonal transitions and eliminating unnatural colour blending – of course, within its capabilities. Unfortunately, it works quite aggressively, so using it comes with trade-offs. In addition to improving gradation, it can also remove film grain or slightly soften facial features. In this case, the choice is yours – do you prefer a more "clean" image, or do you care about preserving the original texture of the material.

Image Scaling in S90F:

In this year's model, Samsung has implemented its proprietary AI processor – NQ4 Gen3, which really handles upscaling quite well. In our test scenes, the TV effectively "pulled up" lower quality towards artificial 4K – the image was more enjoyable to view, and the differences in sharpness between native and scaled content were minimal. Unfortunately, behind all this AI marketing façade lies a certain shortcoming. The S90F struggles with overscan. If you reach for truly archival material – e.g. a VHS tape of your parents' wedding – you have to reckon with the fact that the lower part of the image may get cut off. The function to adapt the image to resolution simply does not work as it should here.

The PUS7000 handles digital image processing quite well. The distortion reduction feature deserves praise, as it effectively smooths unwanted tonal transitions even at a low setting. However, it has its downside: with too aggressive operation, it can introduce undesirable artifacts on the screen. It would be a good idea to experiment with this setting to find the golden mean between a smooth image and the clarity of details.

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

S90F really handles motion excellently – after all, it’s an OLED with a 144 Hz panel, so sports and games look absolutely stunning on it. The image is smooth, clear, and there’s no room for ghosting or blurring, which can sometimes plague cheaper LCDs.

The TV also comes equipped with motion smoothness settings that allow you to customise everything to your liking. We have motion blur reduction and judder reduction – you can set it so that the image is super smooth (even to the point of looking a bit soap opera-like), or more cinematic, with the classic “jumpiness” of 24 frames. The choice is yours, Samsung imposes nothing.

In this regard, 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's actually the norm, and it's hard to expect more. However, the worst part is that the television has no motion smoothing features. There are no supporting systems in place for either movies or sports. We have to 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, motion can appear choppy or unclear. We have no option to enable any smoothers that could alleviate this effect.

When it comes to gaming features – the S90F has absolutely nothing to complain about. Aside from the lack of Dolby Vision, which is already the norm for Samsung. The television operates at 144 Hz, has four HDMI 2.1 ports, so you can easily connect more than one console or PC. Onboard, we also find Game Bar – a practical tool that allows you to quickly preview picture settings, VRR status, ALLM mode, and other useful options. Game Motion Plus deserves special mention – Samsung's proprietary motion smoother that actually works sensibly in games. The image appears smoother, but without any artificial effects or slowdowns.

It's also worth mentioning the HGiG feature, which – and this may be a slight surprise – works correctly. We bring this up because Samsung clearly messed something up in one of the recent updates, and in some models, the option responsible for HGiG simply... disappears from the menu. Setting it up becomes almost impossible. Fortunately, our S90F unit did not have this issue, but the situation is dynamic, so it's worth keeping this in mind and regularly checking for new software versions and information from the manufacturer.

Even though the PUS7000 isn’t marketed as a gaming TV, it doesn't perform as poorly in this category as one might expect. True, it doesn't support 120 Hz refresh rates, which is understandable at this price point, but the manufacturer has included several important features that significantly improve the console gaming experience. The most important of these are VRR and ALLM technologies. VRR is responsible for synchronising the screen with the number of frames generated by the console. This means the image doesn't "tear" and remains consistent even during sudden drops in frame rates while playing. On the other hand, ALLM is a solution that automatically switches the TV to a mode with the lowest latency immediately after detecting 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 brought up on the screen at any time. It allows for a quick view of current settings and connection status without interrupting gameplay, which is a very convenient solution.
