Hisense U8Q vs Samsung OLED S95H (S99H) (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.

When it comes to brightness alone, the S99H is an astronomically bright TV. Its peak brightness in movie scenes can exceed 2800 nits! Regardless of the scene, you can count on powerful HDR effects that practically blind you, and that's exactly what we expect from a top-tier screen. It's inherent to OLED panels that in very bright, full-screen shots they won't sustain as high a brightness as they do with small highlights, but the results are still excellent. In a bright scene from the film The Meg, the sun still exceeded 2200 nits. That means the S99H was able to maintain higher brightness than most Mini LED screens on the market. In terms of brightness, the S99H is currently the best OLED TV we've tested.

Color gamut coverage

The S99H also handles color exceptionally well, which is a direct result of the QD-OLED panel used here. Regardless of the test scenario, whether synthetic test patterns or measurements with film material in the background, the results stayed at a very high level. The S99H easily covers almost 100% of the DCI-P3 gamut, and for the most demanding color space it reaches nearly 90% of BT.2020. That's top-tier performance on the market. These results match what we saw in the new SQD-Mini-LED screens, and in real movie scenes they even outperform RGB Mini LED displays.

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 offers a whole host of picture modes and features, but as usual we recommend choosing Filmmaker Mode, especially if you want the most faithful rendering of the creators' intent. Out of the box the TV is tuned very well, though it has minor shortcomings. This mainly concerns a slight drift in white balance in SDR content and a slightly low gamma. As a result, in a darker room the image can be a bit too bright relative to the reference gamma of 2.4, which is the standard for watching films with the lights off. These are of course small issues, since overall color reproduction remains very good and the errors in ColorChecker measurements are small. However, we know that from a screen of the S99H's class you can and should expect even more, so we had it professionally calibrated.

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.

After professional calibration, FILMMAKER mode looks virtually perfect. Because Samsung offers a rich set of advanced calibration features, we were able to tune the colors to an almost perfect level. Most importantly, we were able to even out the white balance and the gamma curve, which resulted in noticeably better contrast and a more natural image dimensionality. With a profile prepared like this, there's really nothing to nitpick or call a flaw. After calibration, the S99H is capable of delivering an essentially reference-quality image.

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 proprietary Samsung NQ4 Gen3 processor handles upscaling and digital image processing. It does a very good job scaling lower-resolution material to 4K. The picture is sharp but doesn't look artificial or overly sharpened. The only fairly specific drawback appears with very old footage shot at 480p or lower. In those cases the TV can slightly crop the edges of the image.

The processor also copes quite well with artifacts visible in low-bitrate material, for example heavily compressed YouTube videos. The noise reduction feature effectively smooths the image and reduces posterization, but it works rather aggressively. It can remove not only unwanted artifacts but also some fine details and even natural film grain. We, wanting to preserve maximum fidelity to the source material, chose not to use it. However, if someone values a clean, as-smooth-as-possible image over keeping every detail, it can be useful.

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.

Another major advantage of OLED panels is excellent motion reproduction. Thanks to the pixels' near instant response time, the Samsung S99H practically produces no smearing. Fast-moving objects don't show noticeable halos or trailing artifacts, so the TV performs very well for both watching sports and gaming. One quirk of OLED screens compared with LCDs is how they render low frame rate material. With very slow camera movement the image can appear noticeably more stuttery. This can be quite effectively mitigated using a frame interpolation system. Samsung lets you adjust judder reduction and blur reduction separately, making it easy to find a compromise between smoother motion and preserving the cinematic character of the content.

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 😉

Samsung S99H is also an excellent TV for gamers. It offers almost every useful feature... well, maybe except the obvious lack of Dolby Vision for Xbox consoles. It's equipped with four fully functional HDMI 2.1 ports with the full 48 Gbps bandwidth. Thanks to that we can easily use frame-rate synchronization VRR and automatic low-latency mode (ALLM). This year Samsung also has no issues with proper HGiG support, so HDR setup on a console is quick and without unnecessary complications. Samsung is also known for interesting extras in its TVs. In the Game Bar menu you'll find options to add an on-screen crosshair, enlarge the mini-map, or change the aspect ratio of the displayed image (PC).

Particularly noteworthy is Samsung's feature: Game Motion Plus. It's Samsung's proprietary motion-smoothing system that uses interpolation to increase smoothness in games. Input lag then rises to around 40 to 50 ms (depending on the strength of the setting), which is an excellent result compared to the competition. The system makes gameplay noticeably smoother. So if someone has their eye on a demanding game (e.g., GTA 6 😉) that runs at only 30 frames per second on console, the S99H can display it much more smoothly than competing models.
