Hisense U8NQ vs Samsung S90H (WOLED)

Hisense U8NQ demonstrates its capabilities in terms of HDR, achieving a luminance chart score exceeding 2000 nits. In the first, third, and fifth scenes where the screen is bathed in light, the television displayed very high brightness that impresses and allows one to fully enjoy the HDR effect. Unfortunately, in the second and fourth scenes, such as those from the film "Sicario 2", the television encounters difficulties in maintaining brightness, resulting in disappointing scores around 250 nits. Although the large number of dimming zones should theoretically help, the algorithm responsible for their control does not always work perfectly — bright, small elements like the moon or helicopter lights are too dim, which detracts from the typical HDR effect. Instead of dazzling brightness, we get a more subdued light that does not realise the full potential of HDR. Nevertheless, the television deserves praise for its very good coverage of the DCI-P3 colour gamut at 97%. This results in vibrant colours, and most film scenes look really good, significantly enhancing the viewing quality.

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.

The Filmmaker mode on the Hisense U8NQ television can be described as the most accurate mode available on this model. Despite its accuracy, it has significant errors in reproducing reference images, which we will now describe. In the case of HD content, the white balance shows a clear dominance of red, making the image overly pink and warm. The comparative photo below illustrates how this effect impacts content presentation. The brightness characteristics also leave much to be desired — too low a gamma results in an excessively bright screen, and blacks appear elevated, making the overall image seem cooler than it should be.

In the case of 4K HDR content, the problem is the opposite — the white balance shows too great a dominance of blue, resulting in an artificial appearance and an unnaturally sharp image. All of these deviations for both HD and 4K HDR content can be confirmed using the Colour Checker test, which clearly demonstrates how colours deviate from correct standards.

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.

The white balance for both 4K and HD content has been significantly adjusted, which has greatly improved the picture quality. Although some errors are still visible, they are not large enough to heavily affect the perception of the image. A significant improvement can also be noticed in the gamma brightness characteristic — the picture is no longer excessively bright, translating into more natural blacks and better contrast.

However, as with many other Hisense models, there are visible issues with the EOTF curve, which is responsible for managing brightness in high-quality materials. Although at first glance it may seem correct, when the filter is applied to the "EOTF in films" chart, it is evident that the television somewhat "manipulates" 4K content. It is clear that the EOTF curve is significantly below the reference level, leading to an overall dimming of the image compared to the reference. We noticed this effect in previously tested scenes from the films "Pan" and "Billy Lynn." While it is not a serious issue, it is worth noting. It may be of great importance to those seeking a display with the most faithful reproduction of the image. Despite this error, for most, the picture will be more enjoyable. Colours are better represented, and the overall picture quality is significantly improved.

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.

In the context of smoothing tonal transitions, the television Hisense U8NQ unfortunately struggles. The “Smooth and Gradient Picture” function does not yield noticeable effects — there is no improvement in any setting, which is disappointing, especially for demanding scenes with a lot of subtle tonal transitions.

Regarding digital processing, or so-called upscaling, the scene with the model is presented correctly — her outline is clear, without significant cropping. Similarly, thin lines, such as tree branches, exhibit slight jaggedness, but overall it looks plastic and soft, which creates a good impression. Unfortunately, there is also an issue with so-called overscan, which causes cropping of the image at the edges. This can be frustrating when watching content like news, where lower information bars may be partially invisible.

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.

Hisense U8NQ is equipped with a 144 Hz panel, making it an excellent choice for both sports and gaming. The television will also easily satisfy film enthusiasts, as it features a built-in "Ultra Motion Smoothness" processor that allows you to control the smoothness of the image — you can decide whether you prefer a more "framey" picture or a smoother, theatrical effect. This provides great flexibility in adjusting motion quality to the viewer’s individual preferences.

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.

Hisense U8NQ offers everything a gamer may need for comfortable gameplay. The television supports a refresh rate of 144 Hz, ensuring an extremely smooth image, particularly in dynamic action games. The VRR (Variable Refresh Rate) feature allows the image to adjust to varying frames per second, eliminating stuttering and tearing, resulting in exceptionally fluid gameplay. Additionally, the television is equipped with an ALLM (Automatic Low Latency Mode) feature, which automatically switches the television to gaming mode, minimising input lag. This allows players to enjoy responsive gameplay without the need to manually adjust settings.

Hisense U8NQ also supports Dolby Vision, which is important for gamers who value high image quality, high contrast, and deep colours in games that support this format. The television also has a “Game Bar” — a feature that provides quick access to key settings during gameplay, significantly enhancing user convenience.

However, it is worth noting that despite its rich set of features, the Hisense U8NQ does not offer support for the HGiG standard, which is a popular HDR format in games. This may be disappointing for gamers expecting optimal detail reproduction in HDR scenes. Nevertheless, the other features of the television make the Hisense U8NQ a solid choice for console gaming enthusiasts, offering fluidity, high contrast, and user convenience.

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.
