Hisense U7S Pro vs Samsung OLED S95H (S99H) (QD-OLED)

Let’s start with the fact that the U7S Pro is an impressively bright TV — in calibrated mode our measurement equipment showed a staggering 2200 nits of peak brightness!

As we know, peak brightness on test patterns is one thing, and actual film scenes are another. Unfortunately, in real video material the backlight output drops noticeably. The TV can still exceed the 1000-nit mark in the most demanding moments — which is still a great result and fits the mastering standards of most HDR films — but the real challenge lies in the aggressively tuned local dimming algorithms. Because of them, small, bright details like stars or the moon in a night sky are noticeably dimmed. The TV tries at all costs to maintain deep black, which is understandable, but unfortunately this comes at the expense of HDR’s dynamic range and brilliance.

The color reproduction is worth praising. The new U7S Pro is a QLED design that provides very wide color gamut coverage. Unlike last year’s model (U7Q Pro), this year’s variant is a true QLED, not a solution based on a PFS filter. As a result, color saturation has increased noticeably, and coverage of the most demanding BT.2020 color space has topped 81%.

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 tested the U7S Pro, as we always do, in the best factory-tuned picture mode, Filmmaker Mode. The colors can be judged in two ways. The most disappointing was the profile intended for watching SDR content, i.e. traditional broadcast TV, YouTube, and other less demanding material. The image there was clearly yellowish, which turned out to be a direct consequence of a poorly set white balance. As our charts show, there's a large deficiency in the blue component, which drastically affected the overall color temperature. You can see this clearly on the ColorChecker charts and on the color gamut graphs themselves, where most samples shifted toward yellow. Fortunately, the factory HDR mode performed much better. There, color errors hovered around a Delta E of 3, which is a solid result.

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.

We know, however, that Hisense is capable of much more, as previous generations have shown, so we simply couldn't leave the U7S Pro's factory flaws in everyday content as they were. As always in such cases, we had the TV professionally calibrated. The result? The process brought a massive change. After manually correcting the white balance and filling in the missing blue component, the annoying yellow cast vanished as if it had been wiped away. Whites became naturally clean, and skin tones gained a proper, healthy hue. Importantly, the calibration not only tamed the finicky SDR mode but also squeezed the maximum potential out of the panel, reducing average color reproduction errors to levels almost imperceptible to the human eye. The only thing we still have to fault after the whole process is the nature of Mini-LED backlighting and its specific interaction with the HDR signal. Aggressively tuned local dimming algorithms quite strongly interfere with the EOTF luminance curve. As a result, the backlight doesn't always align with the creator's intent — depending on the scene, the curve can run noticeably above or below the reference, which in places disrupts the ideal dynamics of the HDR picture.

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 digital processing of lower-quality signals is top-notch here, thanks to the MediaTek Pentonic 800 processor used in the U7S Pro. Upscaling, the TV's ability to pull lower-resolution content up to 4K, also performs well. We didn't notice any unnatural, sharp contours on screen, and our test image with the model simply looked attractive.

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.

The Hisense U7S Pro uses a panel with a maximum 165 Hz refresh rate at 4K, and in game mode it can even reach 330 Hz at Full HD. However, it's worth remembering that those highest numbers don't matter much in everyday use, because most content still supports at most 120 Hz (for example when playing on a console). Even so, the TV handles motion quite well and performs well for an LCD design.

There's little to fault about the smoothness itself. In the menu you'll find a motion smoothing feature called "Motion Enhancement", which hides two sliders: blur reduction and judder reduction. They allow manual adjustment of the smoother, which works well for both movies and sports, effectively improving the raw TV signal.

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.

If you plan to connect a console or PC to the U7S Pro, you'll be more than happy – this TV is great for gamers. Hisense spared no expense and put in four HDMI 2.1 ports with full 48 Gbps bandwidth. So you won't have to juggle cables, since every port supports the full feature set. There's automatic low-latency mode (ALLM) and VRR, which works across a wide range from 48 Hz up to a cosmic 330 Hz. Of course that 330 Hz is for now a gimmick for owners of powerful PCs, because consoles are capped at 120 Hz anyway, but it's good to have that headroom for the future. The Game Bar is also really useful while gaming. It's a handy in-game menu where, without leaving the TV's main settings, you can quickly change the picture mode, enable a crosshair in the center of the screen, or even switch to an ultra-wide aspect ratio, which PC sim fans will appreciate. The only downside worth knowing about is the incorrect implementation of HGiG in games. The TV ignores the console's instructions for HDR10 output and keeps forcefully altering the image, trying to "improve" it its own way. Because of that, properly configuring HDR in the console menu (where you set brightness using the logo/checkerboard pattern) is a bit more difficult.

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.
