Samsung OLED S90D / S94D (WRGB OLED) vs Hisense U7Q PRO

The Samsung S90D demonstrates impressive brightness performance in the tested film scenes, surpassing the 1000 nits mark in the first four shots—an outstanding result for an OLED display. In the final shot, which features a fullscreen flash of sunlight, the brightness dips to around 500 nits. While this is a decrease, it remains within a very good range, ensuring visibility and detail retention even in bright scenes.

Another key highlight of the Samsung S90D is its remarkable colour coverage, achieving 98% of the DCI-P3 colour space. This means the TV can reproduce an exceptionally wide range of colours, contributing to vivid and lifelike images that are particularly beneficial for films, high-quality video, and HDR content. The high colour accuracy and impressive brightness capabilities, makes the S90D an ideal choice for users seeking premium image quality across various lighting environments, whether in darker rooms or bright, sunlit spaces.

U7Q PRO is truly a bright television. In synthetic tests, it achieved over 1500 nits, which is an outstanding result for this price range. Such brightness – at least in theory – allows for displaying HDR content as intended by creators, even in more demanding scenes with strong light. In practice, it can be very good, but not always perfect. In bright scenes with a large surface area – such as the test screen with intense sunlight from the movie "Pan" – U7Q PRO makes a huge impression. It can almost blind with light, which is definitely an advantage in the context of HDR content. Unfortunately, this is not always maintainable when a lot of small bright details appear on a dark background. In such moments, local dimming algorithms decide to dim some bright elements to maintain good black levels – and the side effect is that some details simply disappear from the frame. This is a classic compromise in mini-LED televisions – and U7Q PRO is no exception. However, with such a large number of dimming zones, one could expect a somewhat more mature algorithm responsible for controlling them. Fortunately, the overall reception of HDR content is very positive. U7Q PRO is not only bright but also colorful; thanks to the PFS LED (QLED) coating, the coverage of the DCI-P3 color palette is at 95%, and BT.2020 is around 73%.

The S90D was tested in Filmmaker mode, which provides good colour reproduction, albeit with some imperfections that may be noticeable to more discerning users. This mode might appear overly warm, and those switching from Standard mode could find the change somewhat jarring. It is important to note that this issue stems from suboptimal settings, such as the white balance, rather than the Filmmaker mode.

In both SDR and HDR content, the device shows a drop in blue tones, resulting in colours appearing warmer than intended. In practice, this means that certain shades, such as sky blue or skin tones, may seem less natural, with a slight pink or yellow tint. The Colour Checker test confirms these deviations, indicating a shift towards warmer hues. In SDR content, the gamma chart reveals slight inconsistencies that make the image appear marginally darker, particularly in shadowed areas, which may obscure finer details in darker scenes.

In 4K HDR content, the EOTF curve exceeds the recommended level, leading to an overly bright display in some parts of the image, which can cause highlights to appear blown out. Overall, the Samsung S90D delivers a solid image straight out of the box, but for the best performance, further calibration is advised, especially with more demanding content.

We tested the U7Q PRO in the best possible picture mode that this model offers – Filmmaker Mode. And indeed, it is this mode that performs best in terms of color reproduction. But that doesn't mean it's perfect. In our test unit, both in SDR and HDR content, the image had a slightly cooled tone. The white balance was shifted towards blue, which made the overall impression feel a bit "cooler." It's not glaring, but definitely noticeable – especially on white backgrounds that, instead of neutral, appeared slightly bluish. Additionally – as we mentioned earlier – the television tends to slightly brighten and oversaturate the image, which is also confirmed by the gamma and EOTF charts. All of this together means that without calibration the image may seem a bit unnatural – too cool, with slightly exaggerated dynamics. That's why we decided to conduct our own calibration – and its effects and charts can be seen below.

After calibration, the Samsung S90D in movie mode exceeds expectations. The white balance for HD and 4K HDR content has been refined to near perfection. While minor imperfections remain, they are so subtle that they don’t significantly impact the overall image quality. The colours are now more balanced, resulting in a natural reproduction of details, particularly in scenes requiring an accurate colour palette. It’s important to note that this model, in this size, uses a WOLED panel, which has a smaller wide colour gamut coverage and doesn't deliver the same vibrant colours as the 65-inch version with its QD-OLED panel.

The contrast has also seen notable improvements. Following calibration, the gamma curve now closely aligns with the expected line, achieving a better balance between the bright and dark areas of the image. The EOTF curve, which previously exhibited issues with overexposed scenes, now produces more accurate results, allowing for improved detail retention in the brighter parts of the image, especially in HDR content.

Thanks to calibration, we managed to tame the white balance in both SDR and HDR content. For SDR materials, the effect is really very good – the image becomes neutral, consistent, and simply pleasant to view. Everything looks as it should.

The performance in HDR is a bit worse. Although the white balance looks correct and overall the image gains in naturalness, unfortunately, delta E errors remain noticeable. Why? Because Hisense does not give us full control over how the U7Q PRO manages brightness in HDR mode. This is where the limitation appears. When we look at the EOTF curve for HDR content, we can clearly see what we mentioned earlier – at the beginning of the graph, there is a noticeable drop, meaning the television dims the smallest sections more than it should. On the other hand, the brightest elements can be illuminated a bit too much. As a result, some details are lost, others are too aggressive, and overall control over brightness does not always align with what we are trying to achieve during calibration.

Does the image look better after calibration? Definitely yes, in terms of color. But when it comes to managing brightness in HDR, we have to accept that the Hisense U7Q PRO will do it its own way.

The S90D TV handles tonal transitions exceptionally well. Thanks to advanced technology, the transitions between colours are smooth and natural. The noise reduction function can further enhance the smoothness of tonal shifts, which is particularly useful in certain situations. However, it's important to note that enabling noise reduction can also blur the natural film grain, diminishing the cinematic quality of the image. For this reason, it’s advisable to use this function with caution, as preserving the natural grain can enhance the character and authenticity of the content being watched.

As always, Samsung excels in image scaling from lower resolutions. The S90D effectively processes lower-resolution content, delivering a clear and accurate picture. The model’s outline is crisp, ensuring the image looks natural and detailed. Even the finer details, such as tree branches, are well-rendered without visible jagged edges that could degrade image quality. Thanks to its effective scaling, the S90D ensures that even lower-resolution content looks appealing, satisfying users who enjoy a wide range of content sources, such as regular broadcast or cable TV.

If someone happens to come across older materials where the issue of color banding appears – Hisense has a solution for that. In the U7Q PRO, we find a feature called "Smooth and Gradient Picture." Set to the "Medium" level, it works really well – it eliminates most of the gradation issues while not smoothing out the entire image, like blur in Photoshop. 😉 Film grain remains, details do not disappear – this is exactly how it should work. Kudos for the implementation!

As for scaling weaker materials, it’s just good. It’s not at the level of the most expensive TVs with advanced upscaling, but older content looks good. There is some mild aliasing at very low resolutions, but that’s completely normal and hard to avoid. On the plus side – even with the oldest materials, there is no overscan effect; the image is not cropped or artificially stretched.

The Samsung S90D television features a 120 Hz panel, with the option to "overclock" to 144 Hz when connected to a compatible PC, offering exceptional motion smoothness. Samsung has long provided a range of image sharpness settings on a ten-point scale, allowing users to tailor the display to their preferences. In the UFO test, the OLED panel shows no signs of blurring, with pixel response instantaneous and effectively capturing dynamic movements. OLED technology is renowned for its performance in this regard, making it one of the best options on the market. The image remains incredibly sharp and detailed, even during fast-paced action, making the S90D an excellent choice for gamers and sports enthusiasts alike.

“Speed” – this word was mentioned most frequently during our tests of the U7Q PRO. The television is equipped with a 165 Hz panel, which is impressive in itself – especially since we are talking about a model in the mid-price range. Of course, PC gamers will benefit the most from its full capabilities, but even during everyday viewing, it is evident that this is a fast and efficient panel. Like most modern televisions, the U7Q PRO can also enhance the smoothness of movies that are primarily shot in 24 frames. In the menu, there is a slider that allows you to adjust the effect to your preferences – from a more cinematic feel, with subtle motion, to stronger smoothing with the characteristic “soap opera effect.”

The Samsung S90D is an ideal choice for gamers, featuring four HDMI 2.1 ports that support key gaming technologies such as Auto Low Latency Mode (ALLM), Variable Refresh Rate (VRR), and HDR Gaming Interest Group (HGIG). These features ensure smoother and more responsive gameplay, greatly enhancing performance during intense gaming sessions. The TV also includes a dedicated Game Bar, which makes managing game settings easy. This functionality allows users to quickly adjust parameters like the aspect ratio offering flexibility for different games and gameplay styles. Customising preferences is straightforward, further enhancing the convenience and enjoyment of gaming.

For PC users, the TV impresses by supporting a refresh rate of 144Hz when connected to a computer. Users with Nvidia or AMD graphics cards can also use G-Sync and FreeSync for a smoother gaming experience. However, it’s important to note that the TV does not support Dolby Vision, which may be a drawback for some. That said, Dolby Vision is not as widely adopted in gaming as in film, so this may not be a significant concern for most gamers. Overall, the S90D offers exceptional features for gamers, making it an excellent choice for those seeking outstanding image quality and modern technological solutions.

The Hisense U7Q PRO is a television that seems almost designed for gamers. It has practically everything you could expect from a gaming screen: variable refresh rate (VRR), automatic mode (ALLM), and as many as four HDMI 2.1b ports with full bandwidth of 48 Gb/s. Additionally, there is a clear and quite functional Game Bar, as well as a well-implemented Dolby Vision GAMING mode that works seamlessly with Xbox Series S and X consoles.

Sounds like perfection? Well, almost. Unfortunately, Hisense has yet to implement the HGiG feature, which is the system's limit on tone mapping on the TV's side. This means that when configuring HDR brightness on the console, we do it "by eye" or look for settings in online guides because the screen doesn't show the real range of its brightness. It's a pity - because HGiG makes it easier to match the console to the TV and helps avoid clipping or overly dark scenes in HDR games.

Fortunately, the other elements work very well. Signal delay (input lag) is low, responsiveness is excellent, and the handling of other functions is flawless. And although not everything worked perfectly, the U7Q PRO can still be recommended to gamers without hesitation.
