Hisense U8Q vs Samsung S90H (WOLED)

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.

The Samsung S90H in the WOLED variant is still an exceptionally bright TV for its price bracket, although it is slightly dimmer compared with the QD-OLED version. That difference is not as pronounced as in last year’s F series, where gaps sometimes reached 500 nits. Here the parameters of both panels are very similar, with differences in peak brightness of only about 100–150 nits. In small-window measurements the S90H with the WOLED panel easily reaches close to 1,500 nits. That headroom lets it phenomenally convey the dynamics of HDR effects — blooms, light reflections and explosions have the right punch, exactly as intended by the studio creators. As with most OLED displays, when a very bright scene fills the entire screen, panel protection systems kick in and brightness naturally falls to around 700 nits. It’s worth stressing 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 stems directly from the different construction of the WOLED panel, which uses an additional white subpixel. As a result, very high-brightness colours don’t achieve quite the same saturation, and the wide-colour volume is slightly more limited than with QD-OLED. That said, in everyday use these differences will be hard for most viewers to notice. Our measured DCI-P3 coverage on the WOLED panel reaches almost 99%, meaning that for the vast majority of real film scenes both variants will present an almost identical image. The real gap only appears in rarer, especially demanding productions that use the ultra-wide BT.2020 gamut. Because of the WOLED panel’s construction, coverage of that standard is roughly 15% lower compared with the S90HAT with a QD-OLED panel, so the brightest, heavily lit HDR colours may appear a touch less vivid.

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.

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 annoying oversaturation seen in more aggressive profiles. However, as is often the case without full calibration, there is unit-to-unit variation. In our test the white balance was a little deficient in the blue component, so the image leaned slightly 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 around 2.2, which caused a small lift in shadow detail. In HDR mode the tuning was a bit better, showing only a slight undersaturation in the red region.

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.

After full calibration, you can safely say the S90H in the WOLED version looks almost perfect. In SDR mode colour errors fall to ultra-low levels and Delta E values very rarely exceed 2. That's a phenomenal result, so if perfectly faithful colour reproduction matters to you, it's definitely worth getting it calibrated. The calibrated HDR mode also performs very well, where the white balance was stabilised and previous deviations eliminated. After professional tuning it's really hard to fault anything, because the TV delivers an image with almost exemplary naturalness and three-dimensionality. The slightly lower score in this category compared with the QD-OLED variant is solely due to the saturation limitation in extremely bright scenes, while the tuning potential and colour fidelity are at the highest level.

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.

When it comes to banding reduction itself, Samsung has kept the same solutions known from last year’s models. The dedicated gradient-smoothing function works quite well and can effectively mask unwanted tonal transitions, which can be useful on a WOLED panel that’s somewhat more prone to banding. However, it’s important to remember it acts aggressively. This mechanism, aside from the artefacts themselves, can remove fine film grain and subtly soften detail. Ultimately it’s a trade-off, but if you want perfectly faithful image reproduction, it’s safer to leave this option off.

There’s also no breakthrough in scaling. The S90H uses the same NQ4 Gen3 processor as its predecessor, so upscaling quality was almost identical. The chip sharpens lower-resolution material very well, pulling a satisfying level of detail out of it. However, Samsung still hasn’t solved the old overscan problem. For some older recordings or archival footage the edges of the image can be slightly cropped. It’s a minor drawback, but it’s a shame the manufacturer still hasn’t fixed it.

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 motion handling the S90H is simply excellent. This year's panel offers its refresh rate boosted to 165 Hz, although in practice the benefit will mainly be for gamers connecting a powerful PC. For movies, TV 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, the OLED panel's lightning-fast response time does the job. Motion is clean, and the ghosting or smearing seen on LCDs simply doesn't occur here.

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 😉

Gamers should feel right at home with the S90H, because Samsung has left few reasons to complain in this area. The TV has four HDMI 2.1 ports, each supporting 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. In last year's models it could cause issues when used with a console, but on the S90H it now works as it should. What really stands out against the competition is Game Motion Plus. It's a specialised motion-smoothing mode for games that works best with titles running at 30 or 60 frames per second. Motion becomes noticeably smoother and 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 big 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 the more useful feature.
