SAMSUNG S90F (WOLED) vs Hisense U8Q

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.

When it comes to HDR, the Hisense U8Q shows its claws. On paper, meaning in synthetic measurement tests, the TV can "push out" nearly 4000 nits of peak brightness. This is a value that most models can only envy. In practice, this translates to very strong light effects in movies – in some scenes we managed to measure real levels from 1500 to 2000 nits, which is a level usually reserved for the absolute top-tier TVs on the market.

Of course, it's not always so perfect. In small, point-like elements, brightness can drop – a good example is scene number 4 from the movie Sicario 2, where instead of thousands of nits we get about 500. But it's worth noting that the effect doesn't disappear completely – the light is still visible, and the image doesn't appear artificially dimmed. This is a typical issue with Mini LEDs, so it’s hard to consider it a major drawback.

However, a huge plus has to be granted for colour reproduction. Thanks to additional coatings improving colour saturation, the U8Q almost covers the entire DCI-P3 colour space (98%), and for the wider BT.2020 gamut it achieved over 80%. This is an excellent result that makes HDR films look juicy, intense, and just very cinematic.

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 have to admit that when the U8Q arrived in our editorial office, we were slightly surprised… and in a good way. Usually, white balance in televisions immediately requires adjustment – it can be too warm or too cold, which immediately causes strange colour errors. Meanwhile, here the situation looks really good straight out of the box. Of course, we’re talking about our unit, so there’s no guarantee that every model will be tuned as well, but in our case, the first impressions were very positive. The only more noticeable issue was related to how the television manages brightness. Looking at the EOTF chart, it’s clear that the U8Q tends to brighten small elements on the screen. This, in turn, caused what we mentioned earlier – slight overexposure and the impression that the whole scene is a bit too bright. However, this is not a flaw that negates the picture, rather an effect characteristic of this model.

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.

Of course, we wouldn’t be ourselves if we didn’t make adjustments to the white balance. After calibration, we managed to level the SDR signal to near perfection – older films, YouTube content, and classic television looked nearly ideal on the U8Q. It’s truly an impressive level that shows this model can do a lot if given a bit of help. Unfortunately, the situation is different with HDR content. The colours themselves don’t pose much of a problem, but the biggest issue with the U8Q remains the EOTF brightness characteristics. In practice, the television tends to "shoot" above how the image should originally look. It’s this slight "blowout" we noticed earlier in comparisons with the best screens on the market. It’s a bit of a shame that this characteristic can't be completely tamed – if we could maintain equally good brightness control in HDR as we do in SDR, we would be looking at an absolutely reference-level image.

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.

Hisense U8Q handles lower quality materials quite well. The television can smooth tonal transitions thanks to the “Smooth and Gradient Picture” feature – it works best on the Medium setting. It nicely dims unwanted bands and irregularities in the image, but importantly, it doesn't remove the film grain or fine details.

The upscaling itself is also at a good level. Image from lower resolutions appears smooth and soft, sometimes a bit too much – we get a plastic effect that may not appeal to everyone. Fortunately, this can be easily corrected with the sharpness slider, allowing you to adjust the image to your personal preferences.

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.

Hisense U8Q has a panel that can refresh the image up to 165 Hz in 4K resolution. In practice, this will mainly benefit PC gamers, but as they say – better to have it than not 😊. For movies and series, we have a built-in smoother called Ultra Motion Smoothing. In the settings, it can be easily adjusted to your own preferences – whether you want a more ‘cinematic’ frame rate or a smooth, theatrical spectacle.

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.

In terms of features, the Hisense U8Q has practically everything one would expect from a modern gaming television. Thanks to the new processor, the manufacturer has managed to implement three HDMI 2.1 ports, so there’s no trouble connecting multiple consoles or a computer. On top of that, it includes all the key technologies – Game Bar with parameter previews, variable refresh rate (VRR), automatic game mode (ALLM)… in a word, a complete set.

But as often happens with Hisense, it’s missing just a bit from perfection. The biggest drawback remains the lack of support for the HGiG format, which allows the TV's brightness to be adjusted to the console and gets the most out of HDR in games. It’s a shame because if this feature were included, we’d have a device practically made for gamers. As it stands, the U8Q remains “only” a very good choice 😉
