Hisense U8NQ vs Samsung S90H (WOLED)

Hisense U8NQ showcases its capabilities in HDR, achieving a brightness level on the luminance chart exceeding 2000 nits. In the first, third, and fifth scenes where the screen is covered in light, the television displays very high brightness, which impresses and allows one to enjoy the full effect of HDR. Unfortunately, in the second and fourth scenes, such as those from the movie "Sicario 2," the television encounters issues maintaining brightness, resulting in disappointing results around 250 nits. Although a large number of dimming zones should theoretically help, the algorithm responsible for their control does not always perform 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 reflect the full HDR potential. Nevertheless, the television deserves praise for its very good coverage of the DCI-P3 colour palette at 97%. As a result, colours are vibrant, and most movie scenes look really good, significantly enhancing the viewing quality.

The Samsung S90H in the WOLED variant is still an exceptionally bright TV for its price class, although it is slightly dimmer compared to the QD-OLED version. The difference is not as pronounced as in last year’s F series, where gaps could reach as much as 500 nits. Here the specs of both panels are very close, and differences in peak brightness are only about 100–150 nits. In small-area measurements, the S90H on the WOLED panel easily reaches levels close to 1500 nits. That headroom lets it portray HDR dynamics phenomenally—specular highlights, reflections or explosions have the right punch, just as the creators intended in the post-production studio. As with most OLED displays, when a very bright scene fills the entire screen, the protection systems that safeguard the panel 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.

Color gamut coverage

The biggest difference between the two S90H variants lies in color reproduction and saturation. This stems directly from the different construction of the WOLED panel, which uses an additional white subpixel. As a result, colors at very high brightness don’t achieve quite the same intensity, and the volume of the wide color gamut is somewhat 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 nearly 99%, which means that in the vast majority of real film scenes both variants will deliver almost identical images. The true gap only appears in rarer, particularly demanding productions that use the ultra-wide BT.2020 gamut. Due to the WOLED panel’s design, coverage of that standard is about 15% lower compared to the S90HAT with a QD-OLED panel, so the brightest, heavily illuminated HDR colors may appear a bit less vivid.

The Filmmaker mode on the Hisense U8NQ TV can be described as the most accurate mode available in this model. Despite its accuracy, it has significant errors in reproducing the reference image, which we will describe now. 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 influences content presentation. The brightness characteristics also leave much to be desired — too low gamma causes the screen to be excessively brightened, and blacks look lightened, making the overall picture seem cooler than it should be.

In the case of 4K HDR content, the problem is reversed — the white balance shows too much dominance of blue, resulting in an artificial character to the image and making it appear unnaturally sharp. These deviations for HD and 4K HDR content can be confirmed with the Colour Checker test, which clearly shows how colours deviate from the correct patterns.

In Filmmaker mode, which we strongly recommend enabling right out of the box, the S90H offers very good factory color tuning. Colors are natural and faithful to the filmmakers' intent, without the intrusive oversaturation found in more aggressive profiles. However, as is usually the case without full calibration, there can be unit-to-unit variation. In our test the white balance lacked a bit of the blue component, causing the image to lean slightly toward warmer, yellowish tones. This was most noticeable in bright scenes, such as the snowy sequences from Star Wars. Additionally, the gamma curve ran slightly low, around 2.2, which resulted in a slight boost to shadow detail. In HDR mode the tuning was a bit better, showing only a slight undersaturation in the red region.

The white balance for both 4K and HD content has been significantly adjusted, greatly improving the image quality. Although some errors are still visible, they are not substantial enough to heavily affect the perception of the image. A notable improvement can also be seen in the gamma brightness characteristics — the image is no longer overly bright, resulting in 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 it may seem correct, once the filter is applied on the "EOTF in movies" graph, it is evident that the TV is somewhat "playing around" with 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 movies "Pan" and "Billy Lynn." While it is not a serious problem, it is worth mentioning. It may be of great importance to those looking for a display with the most accurate image reproduction. Despite this error, the image will be more enjoyable for most. Colours are better reproduced, and the overall image quality is significantly improved.

After full calibration it can safely be said that the S90H in the WOLED version looks almost perfect. In SDR mode color reproduction errors 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 color reproduction it's definitely worth considering calibration. The calibrated HDR mode also performs very well, in which the white balance was stabilized and earlier deviations eliminated. After professional tuning it's really hard to find anything to criticize, because the TV delivers an image with almost exemplary naturalness and dimensionality. The slightly lower rating in this category compared with the QD-OLED variant is solely due to the previously described saturation limitation in extremely bright scenes; the tuning options and color fidelity themselves are at the highest level.

In the context of smoothing tonal transitions, the Hisense U8NQ television unfortunately does not perform well. The "Smooth and Gradient Image" function does not produce noticeable effects — there is no improvement in any setting, which is disappointing, especially in demanding scenes with subtle tonal transitions.

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

When it comes to reducing posterization, Samsung has kept the same solutions as 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 is somewhat prone to banding. However, keep in mind it acts aggressively. This mechanism, aside from removing artifacts, can clean up fine film grain and slightly soften detail. Ultimately it’s a matter of compromise, but if you care about an absolutely faithful 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 the quality of upscaling was almost identical. The chip sharpens lower-resolution material very well, extracting a satisfying level of detail. Samsung still hasn’t dealt with the old overscan issue. With some older recordings or archival material the image edges can be slightly cropped. It’s a minor flaw, but it’s a shame the manufacturer still hasn’t eliminated it.

Hisense U8NQ is equipped with a 144 Hz matrix, making it a great choice for sports and gaming. The television will also easily satisfy movie fans, as it features a built-in "Ultra Motion Smoothness" processor that allows you to control the fluidity of the image — you can decide whether you prefer a more "framey" look or a smoother, cinematic effect. This provides great flexibility in adjusting the quality of motion to the individual viewer's preferences.

In terms of motion handling, the S90H is simply excellent. This year's panel offers a refresh rate boosted to 165 Hz, though in practice the benefit will be realized mainly by 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 its job, so motion is clean and the ghosting or smearing seen on LCD screens simply doesn't occur here.

Hisense U8NQ offers everything a gamer may need for comfortable gameplay. The TV supports a refresh rate of 144 Hz, which ensures an incredibly smooth picture, especially in dynamic action games. The VRR (variable refresh rate) feature allows for adjusting the image to varying frames per second, eliminating stuttering and tearing effects, resulting in an exceptionally smooth gaming experience. Additionally, the TV is equipped with the ALLM (automatic low latency mode) feature, which automatically switches the TV to game mode, minimizing input lag. This allows gamers to enjoy responsive gameplay without manually adjusting the settings.

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

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

Players should feel at home with the S90H, because in that respect Samsung left few reasons to complain. 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. In last year's models it could cause issues when used with a console, but in the S90H it now works as it should. What sets it apart from the competition is primarily Game Motion Plus. It's a special motion-smoothing mode designed for games, which works best with titles running at 30 or 60 frames per second. Motion becomes noticeably smoother, while latency remains at a reasonable level. In our measurements it was under 50 ms, so you can still play comfortably. That's important, because on many TVs turning on a similar smoothing mode causes such a large increase in input lag that controls start to feel 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 far more useful feature.
