Hisense U7NQ vs SAMSUNG OLED S90F (WOLED)

The Hisense U7NQ 65 television demonstrated significant capabilities on the luminance chart, exceeding the 1000-nit barrier and achieving very high brightness results without issue in the first, third, and fifth test scenes. However, as before, in the second and fourth test scenes, for example from the film Sicario 2, there are significant problems with maintaining brightness, and the results around 200 nits are very disappointing. Despite a large number of dimming zones, the algorithm in the television responsible for controlling these zones is unable to react appropriately — in this case, it significantly dims small elements like the moon or the light from a helicopter. The bright light that should blind us is too dim to be called an HDR effect. Nevertheless, it is worth praising the television for its high coverage of the DCI-P3 colour gamut at 96%, which allows it to accurately reproduce most film scenes.

Does the S90F handle not only dark scenes but also bright parts of the image? Definitely yes. Stories about OLEDs as "dark screens" can slowly be regarded as a myth. The Samsung S90F, similar to the LG C5 based on a very similar panel, achieves brightness exceeding 1000 nits. This is a value entirely sufficient to enjoy impressive and dynamic HDR images – both in movies and series. Most of the scenes we tested look stunning, with well-defined lights and high contrast. Of course, OLED technology still has its limitations – with very bright, full-screen sequences, such as the test card from the movie The Meg (5th image), the TV can noticeably dim the image. However, it's worth noting that such scenes are quite rare. One can say 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.

The Chinese manufacturer offers various picture settings with its televisions, but the best mode in this model is undoubtedly the Filmmaker Mode. Despite its name, this mode has its issues: the white balance, although roughly correct, is characterized by a strong dominance of warm tones due to the kick of red colour, both in 4K and HD materials. The Colour Checker test confirms these errors — deviations in samples are visible in inappropriate shades. As for the brightness characteristics, the gamma responsible for HD materials shows values below 2.4, leading to some brightening of the screen. Meanwhile, the EOTF curve shows the television's problems with displaying small light elements, as confirmed by the previously described paragraphs.

Samsung S90F, like most modern TVs, offers many picture modes, but – in line with our testing tradition – we checked it in its best one, which is the Filmmaker mode. As a result, the image looks much more natural than in the default, often oversaturated settings. It was neither overly saturated nor artificially subdued – just closer to what you should see. Of course, "more correct" doesn’t mean "perfect." Our S90F sample unfortunately had significant issues with white balance, particularly in the blue color range, resulting in a slightly yellowish filter applied to most scenes. Someone might say that it looks more "cinematic" – because it's warmer – but let's be honest, George Lucas didn't film Star Wars in sepia 😉 (you'll find the comparison with the scene as always below).

Additionally, in HDR materials, there was a noticeable issue with brightness management. The EOTF curve showed a distinct "spike" in brightness – the TV brightened the image more than it should have, making some effects look too intense and diverging from the reference. Thankfully, some of these issues can be eliminated with professional calibration – you can read about its effects later in the review.

Hisense televisions offer many tools for image correction, allowing users to adjust settings to their preferences. Therefore, we decided to utilize these capabilities to bring the image quality closer to reference standards. In the case of white balance, we managed to eliminate the dominance of red, resulting in more neutral colours, which allowed for a more realistic image in both 4K and HD materials. A similar improvement was noticed in the brightness characteristics. Gamma, which previously led to excessive screen brightness, was corrected, contributing to better detail representation in the darker areas of the image while maintaining a natural tonal balance.

However, the biggest challenge was the calibration of the EOTF curve, which is responsible for brightness in 4K materials. At first glance, the EOTF value appeared almost perfect, but detailed tests showed a slightly different outcome. Upon closer inspection—especially using the filter on the right side of the EOTF chart—we noticed how the television manipulated 4K film materials, often significantly boosting brightness. This effect was particularly noticeable in scenes from films such as Pan and Billy Lynn, where the television attempted to artificially increase the brightness of elements, affecting their naturalness. Despite these imperfections, the calibration yielded positive results, especially in terms of tonal improvement. For most users, the final effect should be satisfactory, especially if they aim to bring image quality closer to professional reference standards.

After calibration, we managed to eliminate almost all the aforementioned errors. Older movies in SDR quality finally look as they should – without the sepia effect or artificial aging of the image. The atmosphere of the classics is returning to its rightful place (you're welcome, Star Wars fans), and the colors 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 an almost reference way. Yes, the most demanding users may notice minimal deviations in brightness, but to be honest – most viewers won't even notice that. And it’s no wonder, because the vast majority of errors are below the ΔE 3 threshold, which is below the visibility threshold. After calibration, the S90F (WOLED) becomes a truly excellent display – one that you can enjoy nearly perfect image quality on.

When it comes to smoothing tonal transitions, despite the presence of the "Smooth and Gradient Image" feature in the test sequence, we did not notice that the feature added anything — we recommend turning it off. As for upscaling, the television handled our model well, and the branches in the background are not excessively jagged — the image seems quite plastic. However, it was slightly cropped by the so-called overscan.

Digital image processing in the S90F:

Fortunately, Samsung, as in most of its models, can effectively deal with the unwanted posterization effect in the S90F. The function responsible for this element is noise reduction, which quite nicely smooths out tonal transitions and eliminates unnatural color joins – of course, within its capabilities. Unfortunately, it works quite aggressively, so using it comes with compromises. In addition to improving gradation, it may also remove film grain or gently 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 the S90F:

In this year's model, Samsung has implemented its own AI processor – NQ4 Gen3, which really manages quite well with upscaling. In our test scenes, the television effectively "pulled up" lower-quality content towards artificial 4K – the image was more pleasant to view, and the differences in sharpness between native and scaled content were minimal. Unfortunately, behind this entire AI marketing façade lies a certain shortcoming. The S90F does not handle overscan well. If you reach for truly archival materials – like a VHS tape of your parents' wedding – you must reckon with the fact that the lower part of the image may be cut off. The image adaptation function to the resolution simply does not work here as it should.

Hisense U7NQ has a refresh rate of 144 Hz, which definitely contributes to smooth motion. For movie enthusiasts, there are two features available: judder reduction and motion blur reduction. The judder reduction feature minimizes the effect of so-called judder, which is the unpleasant stuttering of the image, particularly noticeable at lower frame rates. On the other hand, motion blur reduction helps sharpen fast-moving objects, which is useful when watching dynamic action scenes.

As for motion blur, the TV has a decent response time, so excessive blurriness is not visible, except in specific situations, such as the test with the little green alien on a dark background. In such cases, slight artifacts may appear, but overall, the TV handles dynamic images well, providing satisfactory motion quality.

S90F really handles motion great – after all, it's an OLED with a 144 Hz panel, so sports and games look simply amazing on it. The picture is smooth, clear, and there's no room for ghosting or blurring that sometimes plagues cheaper LCDs.

The TV is also equipped with motion smoothing settings that allow you to tailor everything to your liking. We have motion blur reduction and judder reduction – you can set it up to make the picture super smooth (even to that soap opera effect), or more cinematic, with the classic "choppiness" of 24 frames. The choice is yours; Samsung doesn't impose anything.

Hisense U7NQ offers everything a gamer might need for comfortable gameplay. The TV supports a refresh rate of 144 Hz, providing an incredibly smooth image, especially in dynamic action games. The VRR (Variable Refresh Rate) feature ensures that the image adapts to changing frames per second, eliminating stuttering and tearing. Additionally, there is an ALLM (Auto Low Latency Mode) feature that automatically switches the TV to game mode, minimizing input lag.

The TV also supports Dolby Vision, which is particularly important for gamers who value high contrast and vivid colors in games that support this format. The Hisense U7NQ also has a Game Bar feature that allows quick access to essential settings during gameplay, as well as support for G-Sync technology, which further reduces image tearing.

Unfortunately, despite the wide range of features, support for the most popular HDR format in gaming — HGiG — is lacking. This may be disappointing for gamers who expect optimal detail representation in HDR scenes. Nevertheless, the remaining features make the Hisense U7NQ a solid choice for any console gaming enthusiast.

When it comes to gaming features – we have absolutely no complaints about the S90F. Aside from the lack of Dolby Vision, which is already the norm for Samsung. The TV operates at 144 Hz, has four HDMI 2.1 ports, so you can easily connect more than one console or PC. It also includes Game Bar – a practical tool that allows you to quickly preview picture settings, VRR status, ALLM mode, and other useful options. Game Motion Plus is also noteworthy – Samsung’s proprietary motion smoother, which uniquely works well in games. The image feels smoother without any artificial effects or slowdowns.

It’s also worth mentioning the HGiG feature, which – surprisingly – works correctly. We mention this because Samsung clearly broke something in one of its recent updates, and in some models, the option responsible for HGiG simply... disappears from the menu. Setting it becomes virtually 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.
