Hisense U7NQ vs Samsung OLED S90D / S94D (WRGB OLED)

The Hisense U7NQ 65 television showed considerable potential on the luminance chart, exceeding the 1000 nits barrier and easily achieving very high brightness results in the first, third, and fifth test scenes. However, as 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 a large number of dimming zones, the algorithm in the television responsible for controlling these zones fails to respond adequately — in this case, it significantly dims small elements such as the moon or the light from a helicopter. The bright light that should dazzle us is too dim to be considered 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 represent most film scenes well.

In the tested film scenes, the television Samsung S90D achieves impressive brightness results, exceeding the 1000 nits barrier in the first four shots, which can be considered an outstanding result. In the case of the last shot, where a full-screen flash of sunlight is visible, the brightness drops to around 500 nits, but still remains at a very good level. Additionally, the television impresses with a DCI-P3 colour gamut coverage measurement of 98%, ensuring an extraordinarily rich and realistic colour reproduction, further enhancing the picture quality. This result makes the Samsung S90D an ideal choice for those expecting high-quality images in a variety of lighting conditions.

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

The S90D television has been tested in Filmmaker mode, which offers good colour reproduction, although with some imperfections that may be noticeable to more discerning users. This mode may seem a bit too warm, and users who switched from Standard mode may experience a slight shock. It is worth noting that this situation is caused by poor settings, such as in the white balance, rather than the Filmmaker mode itself. In both SDR and HDR content, the device exhibits drops in blue colour, making colours warmer than they should be. In practice, this means that some shades, such as sky blue or skin tones, may appear less natural and more tinged with pink or yellow. The Colour Checker test confirms these deviations, showing shifts towards warmer tones. In SDR content, the gamma graph indicates slight fluctuations, resulting in a minimally darker image, especially in shadows. This can affect less defined details in darker scenes. Conversely, in 4K HDR materials, the EOTF curve is above the recommended line, leading to overly bright displays in certain parts of the image, which can cause clipping in the brightest areas. Overall, Samsung S90D presents a solid picture right out of the box, but for the best effects, especially with more demanding content, additional calibration is recommended.

Hisense televisions offer many image correction tools that allow users to adjust settings to their own preferences, which is why we decided to take advantage of these capabilities to bring the image quality closer to a reference standard. In terms of white balance, we were able to eliminate the dominance of the red colour, resulting in more neutral hues, which allowed for a more realistic image in both 4K and HD materials. We observed similar improvements in brightness characteristics. The gamma, which previously led to excessive screen brightness, was corrected, contributing to better detail reproduction in the darker areas of the image while maintaining a natural tonal balance.

However, the biggest challenge was calibrating the EOTF curve, which corresponds to brightness in 4K materials. At first glance, the EOTF value appeared nearly perfect, but detailed tests showed somewhat different results. When we examined it more closely — 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, particularly if they are keen on bringing the image quality closer to professional reference standards.

After calibration, the Samsung S90D television in movie mode looks even better than one might have expected. The white balance, for both HD and 4K HDR content, has been improved almost to perfection. Although minor flaws can still be noticed, they are minimal enough not to significantly affect the picture quality. The colours are more balanced, which translates to a natural reproduction of details, especially in scenes requiring a precise colour palette. It is worth noting that this model in this size is equipped with a WOLED panel, which has less coverage of the wide colour gamut and does not offer as rich colours as, for example, the 65-inch version, which is equipped with a QD-OLED panel.

Contrast has also seen significant improvement. The gamma graph post-calibration is much closer to the expected line, providing better balance between bright and dark areas of the image. The EOTF curve, which prior to calibration showed issues with overexposed scenes, now presents better results. This effect allows for greater detail retention in bright parts of the image, especially in HDR materials.

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

Television S90D performs very well at smoothing tonal transitions. Thanks to the applied technology, the transitions between colours are more fluid and natural. There is also the option to use noise reduction, which further smooths tonal transitions, which can be useful in certain situations. However, it is worth remembering that enabling noise reduction can also lead to the smoothing of desirable film grain, which in turn could reduce the cinematic atmosphere of the image. For this reason, caution is advised when using this feature, as it is better to leave the natural grain that adds character and authenticity to the viewed content.

Samsung, as always, does not disappoint and excels in the area of scaling images from lower resolutions. The S90D Samsung television effectively processes lower resolutions, as can be seen in the visible image. The outline of the model is clear and accurate and, as a result, looks natural and detailed. Moreover, the branches of the trees are well-rendered, showing no significant jaggedness, which could diminish the image quality. Thanks to effective scaling, even materials in lower resolution present attractively on the screen, pleasing users who prefer various sources of content such as regular antenna/cable television.

Hisense U7NQ has a refresh rate of 144 Hz, which definitely contributes to smooth movement. For film enthusiasts, two functions are available: judder reduction and motion blur reduction. The judder reduction function minimises the effect known as judder, or unpleasant jumps in the image, particularly noticeable at lower frame rates. Meanwhile, motion blur reduction helps to sharpen fast-moving objects, which is useful when watching dynamic action scenes.

As for ghosting, the television has a good response time, meaning excessive ghosting is not visible, except in specific situations, such as the test with the little green man on a dark background. In such cases, slight artefacts may appear, but overall the television handles dynamic images well, providing satisfactory motion quality.

Samsung S90D TV is equipped with a 120 Hz panel, with the possibility of "overclocking" to 144 Hz with the appropriate PC configuration, providing exceptional motion fluidity. Samsung has been offering a variety of sharpness settings on a ten-point scale for years, allowing users to adjust the display to their preferences. In the UFO test, thanks to the use of an OLED panel, there's no sign of any smearing. The pixel response is instantaneous and perfectly captures dynamic movements. In this aspect, OLED technology is considered one of the best on the market. The picture is extremely sharp and detailed, even during fast actions, making the S90D TV an ideal choice for gamers and sports enthusiasts.

Hisense U7NQ offers everything a gamer might need for comfortable gameplay. The television 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 varying frames per second, eliminating stuttering and screen tearing. Additionally, there is an ALLM (automatic low latency mode) feature, which automatically switches the television to game mode, minimising input lag.

The television also supports Dolby Vision, which is particularly important for gamers who appreciate high contrast and rich colours in games that support this format. The Hisense U7NQ also has a Game Bar feature that allows quick access to the most important settings during gameplay, as well as support for G-Sync technology, further reducing screen tearing effects.

Unfortunately, despite a 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 other features make the Hisense U7NQ a solid choice for any console gaming enthusiast.

The Samsung S90D TV is perfectly adapted to the needs of gamers, offering four HDMI 2.1 ports that support key features such as Auto Low Latency Mode (ALLM), Variable Refresh Rate (VRR), and HDR Gaming Interest Group (HGIG). With these technologies, gamers can enjoy smoother and more responsive gameplay, significantly affecting comfort and performance during intense gaming sessions. An additional advantage of the television is the special Game Bar, which allows for easy management of game settings. This functionality enables quick adjustments to parameters such as changing the TV's screen aspect ratio, which can be useful in various games and types of gameplay. Users can easily customise their preferences, making the use of the TV during gaming even more convenient and enjoyable. As for PC users, the TV pleasantly surprises. When connected to a computer, the panel is capable of achieving a refresh rate of 144Hz, and users of Nvidia or AMD graphics cards can enjoy features such as G-Sync and FreeSync. It should be noted, however, that the TV does not support Dolby Vision, which may be a drawback - but it's worth bearing in mind that Dolby Vision is not as popular for games as it is for films. Nevertheless, the S90D TV still offers excellent features for gamers, making it a great choice for gaming enthusiasts who seek top-notch picture quality and modern technological solutions.
