Hisense U8Q vs Samsung OLED S90F (QD-OLED)

When it comes to HDR, Hisense U8Q shows its claws. On paper, meaning in synthetic measurement tests, the television can "score" nearly 4000 nits of peak brightness. That's a value that most models can only envy. In practice, this translates to very strong lighting effects in films – in some scenes, we managed to measure a real 1500 to 2000 nits, which is a level usually reserved for the absolute top of televisions on the market.

Of course, it's not always that perfect. With small, pinpoint elements, brightness can drop – a good example is scene number 4 from the movie Sicario 2, where instead of thousands of nits, we get around 500. But it's worth noting that the effect doesn't vanish completely – the light is still visible, and the image doesn't feel artificially dimmed. This is a typical drawback of Mini LEDs, so it's hard to consider it a significant minus.

On the huge plus side, color reproduction deserves high praise. Thanks to additional coatings that improve color saturation, the U8Q nearly covers the full DCI-P3 color space (98%), and in the case of the wider BT.2020 gamut, it achieved a score of over 80%. This is an excellent result, making HDR films look juicy, vibrant, and simply very cinematic.

The biggest difference between the 65-inch S90F and the other versions is brightness. The QD-OLED panel can achieve up to 1700 nits in laboratory tests, which is over 500 nits more than the variant with the WOLED panel. This translates to a significantly stronger and more engaging HDR effect. In most scenes, bright parts of the image look fantastic, and we have to admit we were pleasantly surprised because we expected results closer to the WOLED version, but we got an effect that makes a big impression even in movies. As with any OLED, there are moments when the panel has to limit brightness somewhat. This mainly concerns full-screen, very demanding scenes – for example, in the last test frame from the movie "The Meg," brightness drops to around 800 nits. However, it's hard to consider this a flaw since it’s still an excellent result, unprecedented in OLED TVs in this price range. All signs indicate that the 65-inch S90F could be one of the best choices this year for those looking for a strong OLED at a reasonable price. Another advantage of the QD-OLED panel in HDR content is its color gamut coverage. Thanks to quantum dots, the television achieves almost full 100% of the DCI-P3 color gamut and nearly 90% of the BT.2020 gamut. These values place it alongside much more expensive models and make it exceptional in its class.

We have to admit that when the U8Q arrived at our editorial office, we were slightly surprised… and positively so. Usually, televisions require immediate white balance correction – it can be too warm or too cold, which immediately leads to strange color errors. Meanwhile, here the situation looks really good right out of the box. Of course, we are talking about our unit, so there’s no guarantee that every model will be tuned as well, but in our case, the first impressions were very positive. The only more pronounced issue was related to how the television manages brightness. Looking at the EOTF chart, it is evident that the U8Q tends to brighten small elements on the screen. This, in turn, caused what we mentioned earlier – slight overexposures and the impression that the entire scene can sometimes be a bit too bright. However, this is not a flaw that undermines the image, rather it is a characteristic effect of this model.

Samsung S90F, like most modern televisions, offers several picture modes, but in keeping with our tradition, we checked it in the most important one, which is Filmmaker. This setting makes the picture look much more natural than in the default, often oversaturated modes. It is neither overly saturated nor artificially subdued – just closer to what you should actually see. However, that doesn't mean it's perfect. The S90F had noticeable shortcomings in white balance, primarily in the blue range, which created a slightly yellowish filter effect on most scenes. One might argue that it looks more "cinematic" because it's warmer, but let's not kid ourselves – George Lucas didn't shoot Star Wars in sepia 😉 (you'll find a comparison with a scene below as always). In HDR materials, there was also a problem with brightness management. The EOTF curve clearly showed that the television brightens the picture more than it should, which led to some effects looking too intense and deviating from the reference. Fortunately, many of these shortcomings can be eliminated through professional calibration – we will discuss the effects of this procedure further in the test.

Of course, we wouldn't be ourselves if we didn't make adjustments to the white balance. After calibration, we managed to align the SDR signal to near perfection – older movies, YouTube content, and classic television looked almost perfect on the U8Q. This is truly an outstanding level that shows this model can do a lot if given a little help. Unfortunately, the situation is different with HDR content. The colors themselves aren't a major issue, but the biggest flaw of the U8Q remains the EOTF brightness characteristics. In practice, the TV tends to "blow out" beyond how the image should look in its original form. It's that slight "blown out" effect we saw earlier in comparisons with the best screens on the market. It's a bit of a shame that this characteristic can't be fully tamed – if we could maintain similarly good control over brightness in HDR as we do in SDR, we would have an absolutely reference-quality image.

Calibration quickly showed that the S90F has a substantial reserve of capabilities. The image in SDR immediately gained a natural quality – classic films stopped looking as if someone had applied a yellowish filter to them, and the colors regained their true character. It’s a return to the atmosphere of the original, without the impression that someone tried to "age" it artificially. In HDR content, the difference was even more pronounced. The EOTF curve was managed almost to a reference level, and any deviations are so subtle that most viewers won't even notice them. In practice, the S90F after calibration displays an image very close to perfection. Compared to the WOLED version, it performs even better – mainly due to the wider color gamut coverage, which makes the colors look fuller and more vibrant.

The Hisense U8Q handles lower-quality materials quite well. The TV can smooth out tonal transitions thanks to the "Smooth and Gradient Picture" feature – it works best when set to Medium. At that setting, it nicely reduces unwanted bands and unevenness in the image, but importantly, it does not remove cinematic grain or fine details.

The upscaling itself is also at a good level. Images from lower resolutions look smooth and soft, at times even a bit too much – we get a plastic effect that may not appeal to everyone. Fortunately, this can be easily adjusted with the sharpness slider to fit personal preferences.

The S90F performs really well here, although there are some comments that are repeated in the case of most Samsung TVs. The noise reduction feature can effectively smooth out unwanted color transitions in lower-quality materials, such as television or YouTube, making them simply look better. However, it should be noted that it operates quite aggressively and can also soften elements that we wouldn't want to touch, like facial details. Therefore, if we want to use it, it’s best to use it in the "medium" setting and be aware of the compromise it brings. The upscaling itself is at a high level – low-quality materials are enhanced towards a 4K-like image. The only caveat is that the S90F can still have problems with so-called overscan, which is slight trimming of the edges in very poor materials like 576p and lower.

Hisense U8Q has a display that can refresh the image up to 165 Hz in 4K resolution. In practice, this will mainly be utilized by PC gamers, but as they say – it’s better to have it than not 😊. For movies and series, we have a built-in smoothness enhancer called Ultra Smooth Motion. In the settings, it can be easily adjusted to personal preferences – whether we want more of a "cinematic" frame rate or a smooth, theatrical spectacle.

S90F is an OLED with a refresh rate of 144 Hz, but in practice, what matters most is how it performs at 120 Hz, as this frequency is the most significant when watching sports. The QD-OLED panel is no different in this regard from WOLED panels—the pixel response is almost instantaneous, allowing motion to be rendered with surgical precision. The effect is easy to predict. The image is practically free of ghosting, making gaming on consoles, matches, or other sports broadcasts a great pleasure on the S90F.

Fans of movies and series are not forgotten either. Like every Samsung TV with a refresh rate of 120 Hz and above, the S90F is equipped with a proprietary motion smoother called "Image Clarity." Here, we find two sliders—motion blur reduction and judder reduction—that allow you to improve the fluidity of materials recorded at 24 frames and adjust the effect to your personal preferences.

In terms of features, the Hisense U8Q has practically everything one could expect from a modern gaming television. Thanks to the new processor, the manufacturer has managed to implement as many as three HDMI 2.1 ports, so there is no problem connecting multiple consoles or a computer. In addition, it includes all the key technologies – Game Bar with parameter monitoring, variable refresh rate (VRR), automatic low latency mode (ALLM)... in short, a complete set.

But as is often the case with Hisense, it falls a bit short of perfection. The biggest drawback remains the lack of support for the HGiG format, which allows you to adjust the television's brightness to the console and get the most out of HDR in games. It's a shame because if this feature were included, we would have a device practically made for gamers. As it stands, the U8Q remains "just" a very good choice 😉

S90F is a television that truly brings a lot of joy when gaming. Right off the bat, we get four full-fledged HDMI 2.1 ports, which means you can connect all consoles and PCs without having to figure out which device takes priority. This is a convenient and practical solution that is not a given with other manufacturers. Additionally, there are key features such as the automatic game mode (ALLM), which switches the screen to low-latency settings, and VRR frame synchronization working over a wide range from 48 to 144 Hz. This ensures that the picture remains smooth regardless of whether we are playing fast-paced online shooters or calmer story-driven titles. Another noteworthy feature is the Game Bar – a panel that allows quick access to several useful additions. For example, you can turn on an additional crosshair in the center of the screen, enlarge the minimap, or, in the case of a PC, change the aspect ratio. Finally, there is also the unique Game Motion Plus mode exclusive to Samsung. Its purpose is to smooth out older or less optimized titles, and it actually works quite well. Thanks to this mode, even less polished games can look better and provide more enjoyment than on other televisions that theoretically offer the same technical specifications.
