Hisense U7NQ vs SAMSUNG S90F (WOLED)

The Hisense U7NQ 65 television showed impressive capabilities on the luminance chart, surpassing the 1000 nit barrier and achieving very high brightness scores effortlessly in the first, third, and fifth test scenes. However, just like before, in the second and fourth test scenes, such as from the film Sicario 2, there are significant issues with maintaining brightness, and results around 200 nits are very disappointing. Despite the large number of dimming zones, the algorithm in the television that controls these zones is unable to respond adequately — in this case, it strongly dims small elements like the moon or the light from a helicopter. Bright light that should dazzle us is too dim to be considered an HDR effect. Nevertheless, the television deserves praise for its high coverage of the DCI-P3 colour gamut, at 96%, which allows it to accurately render most film scenes.

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.

The Chinese manufacturer offers various picture settings in its televisions, but the best mode in this model is undeniably the Filmmaker Mode. Despite its name, this mode has its issues: the white balance, although roughly correct, is characterised by a strong dominance of warm tones due to the prominence of red hues, both in 4K and HD material. The Colour Checker test confirms these errors — deviations in samples can be seen in improper shades. As for brightness characteristics, the gamma responsible for HD material shows values below 2.4, which leads to some screen brightness. 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 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.

Hisense TVs offer a range of image correction tools that allow you to adjust settings to your own preferences, which is why we decided to use these capabilities to bring the image quality closer to reference standards. In terms of white balance, we were able to eliminate the dominance of red, resulting in more neutral colours, which allowed for a more realistic image in both 4K and HD content. We noticed a similar improvement in brightness characteristics. The gamma, which previously led to excessive brightness on the screen, has been corrected, contributing to better detail reproduction in darker areas of the image while maintaining natural tonal balance.

However, the biggest challenge was calibrating the EOTF curve, which is responsible for brightness in 4K content. At first glance, the EOTF value looked almost perfect, but detailed tests revealed somewhat different results. When we looked closer — especially using the filter on the right side of the EOTF chart — we noticed how the TV manipulated 4K film content, often significantly boosting brightness. This effect was particularly noticeable in scenes from films like Pan and Billy Lynn, where the TV attempted to artificially increase the brightness of elements, impacting their naturalness. Despite these imperfections, the calibration yielded positive results, especially in terms of tonal improvement. For most users, the end result should be satisfying, particularly if they are looking to bring image quality closer to professional reference standards.

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.

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 quite well, and the branches in the background are not overly jagged — the image appears quite plasticky. However, it has been slightly cropped by the so-called overscan.

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 U7NQ has a refresh rate of 144 Hz, which definitely enhances motion smoothness. For movie enthusiasts, there are two features available: judder reduction and motion blur reduction. The judder reduction function minimises the effect of so-called judder, that is, unpleasant image jumps, particularly noticeable at lower frame rates. Meanwhile, motion blur reduction helps to sharpen fast-moving objects, which is useful when watching dynamic action scenes.

When it comes to trailing, the television has a decent response time, which means excessive trailing is not visible, except in specific situations, such as the test with the alien on a dark background. In such cases, slight artifacts may appear, but overall the television handles dynamic images well, providing satisfying motion quality.

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 U7NQ offers everything a gamer might need for comfortable gameplay. The TV supports a refresh rate of 144 Hz, providing an extremely smooth image, especially in dynamic action games. The VRR (variable refresh rate) feature ensures the image adapts to varying frames per second, eliminating stuttering and tearing. Additionally, there is an ALLM (automatic low latency mode) function that automatically switches the TV into game mode, minimising input lag.

The TV also supports Dolby Vision, which is particularly important for gamers who value high contrast and rich colours in games that support this format. The Hisense U7NQ also features a Game Bar, allowing quick access to key settings during gameplay, as well as support for G-Sync technology, further reducing image tearing.

Unfortunately, despite its wide range of features, it lacks support for the most popular HDR format in gaming — HGiG. This may be disappointing for gamers who expect optimal detail reproduction 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 – 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.
