Hisense UR9S vs Hisense U7S / U77SE

Hisense UR9S is undoubtedly a show of strength from the Chinese manufacturer when it comes to luminance. On a synthetic test pattern the panel reached as much as 2600 nits, which is an impressive result. However, it is important to clearly separate laboratory results from filmic realities. In real material the UR9S behaves much more... restrained. Maximum brightness peaks in balanced scenes hover around 1500 nits. In demanding, dark shots, where algorithms must at once maintain deep black and precisely light small details, brightness can fall drastically, even to around 400 nits. The discrepancy between the chart and reality is therefore huge. This is a direct consequence of the conservative behaviour of the local dimming system. When a bright object occupies a large part of the frame, the system can easily sustain a high brightness. But in night scenes the priority becomes protecting black and combating the halo effect (unsightly glows around bright edges). To avoid contrast degradation, the TV drastically limits light output. Even so, the UR9S can still produce a very powerful, immersive HDR effect that impresses in bright, spectacular sequences.

Colour gamut coverage

On test patterns the Hisense UR9S performs excellently in terms of colour. Its coverage of the DCI-P3 gamut is almost 100%, and the wide BT.2020 as much as 93%. Those are results even the best QD-OLED TVs do not achieve. But again, synthetic measurements are one thing, films and series another. In real-world scenes the figures fell to 93% for DCI-P3 and 81% for BT.2020. That's still a great result, but the advantage of RGB Mini LED is no longer as dramatic as manufacturers claim in their marketing materials. One could even say that currently their capability is similar to TVs equipped with quantum dots, the so-called QLED. So why does this happen? To a large extent colour reproduction here depends on the specifics of how the backlight zones operate. When a strongly saturated colour sits next to white or another, more complex element, a single zone has to handle both parts of the picture at once. Under those conditions the backlight cannot maintain extreme saturation of a given colour on screen, because the emitted light takes on a more white-like character. In the UR9S this has been refined quite well, but still not enough for the TV to maintain such high colour saturation in every situation.

The Hisense U7S has considerable potential for HDR display, but it cannot exploit that potential in every scene. On a test pattern it reaches around 1,100 nits, so the backlight itself is very strong. In our brighter film scenes we measured about 640 to 745 nits. That is still plenty for the sun or bright highlights to have a clear bloom and to show an advantage over SDR material. When the TV needs to brighten a larger portion of the image, it handles it fairly well.

The problem appears with small highlights on a dark background. Each of the 192 zones covers an area much larger than a tiny point on the screen. If the TV were to light that whole zone strongly, it would also brighten the area around the highlight. Hisense tries to avoid that and dims the entire zone. This makes blacks look better, but a small bright object that should attract the eye also loses intensity. That is why in two more demanding scenes we recorded only 297 and 154 nits. The difference is large: in one shot HDR can impress, and in the next small highlights are noticeably muted. The U7S therefore prioritises preserving deep blacks, even at the expense of bright details. With that number of zones it is an understandable compromise, but worth bearing in mind — the peak 1,100 nits tells us about the backlight’s capability, not how brightly the TV will show every element of a film.

Colours

Hisense describes the U7S as ULED, but that is a marketing name, and it is a PFS phosphor backlight that expands the colour palette here. In our measurements the TV covered about 91% of the DCI-P3 colour space and 71% of BT.2020. Those are good results, though they fall short of the best screens on the market. The largest shortfall is in green — the TV does not even reach the DCI-P3 boundary here, so the most intense shades will be less saturated than they should be. Most colours in HDR films and series still look suitably vibrant. A positive is the repeatability of the results. Gamut coverage on test patterns and in film scenes is practically identical.

We tested the Hisense UR9S in Filmmaker Mode, which out of the box provides the best image reproduction. With HDR material the TV performed quite well in this regard. The white balance showed no major errors, and the luminance response, although it had the characteristic Hisense profile, was maintained at a reasonable level. The picture was therefore neither excessively brightened nor noticeably colour-distorted. The same mode performed much worse with SDR material, the kind of content we watch most often, such as broadcast television or YouTube. The white balance was strongly shifted towards red and blue, giving the picture a slight pink tint. This also affected the gamma curve. Instead of approaching the reference value of 2.4, it was closer to 2.0, making the image look too bright, particularly in midtones and darker areas. Filmmaker Mode therefore remains the best out-of-the-box choice, but it is not a mode without faults.

Out-of-the-box colours on the Hisense U7S are decent, but there are a few areas to improve. In SDR there is a red bias in the white balance, which makes the picture too warm and, in places, slightly pink. You can notice this on faces and on bright, neutral surfaces. The gamma also runs below the target, so the TV brightens the image, particularly in darker areas. That makes shadow detail easier to see, but the scene loses some of its depth.

In HDR the white balance is somewhat more even, but not entirely neutral, with a shortage of blue in the mid-tones and a lack of red in the brightest parts. A bigger issue is how brightness is rendered. The EOTF curve shows a large portion of the mid-tones being lifted, causing the picture to look brighter than the source intends. Color Checker measurements are also weaker than in SDR: many errors are around 3 to 4, and some reach as high as 8. Colours can therefore look attractive, but they are not always faithful to what we should see. There is room for improvement here and we will see how much can be corrected through calibration.

After calibration the biggest improvement was in SDR mode, although we also refined the HDR picture. Hisense offers a lot of calibration settings in the menu, so we were able to precisely correct the white balance and the remaining image errors. The most important change was removing the pink tint that had previously been clearly visible in SDR material. After calibration the picture looks much more natural, especially in everyday content such as TV or YouTube.

Colour reproduction errors on the ColorChecker chart are very small after calibration. The vast majority of colours fall below values of 2 to 3, which is at a level very difficult to discern with the human eye. The only thing we could not completely eliminate is the tone-mapping approach characteristic of Hisense TVs in HDR. It affects how brightness is distributed in films and can subtly 'enhance' the image, rather than sticking exactly to the creators' intent. For less experienced viewers this can produce a stronger 'wow' effect, but it will not always fully match how the material should look.

Calibration of the Hisense U7S brought the biggest improvements with SDR material. We managed to even out the white balance, so the previous warm tint has gone and whites and greys now look neutral. Gamma is also now very close to the reference, and the TV no longer brightens the picture unnecessarily, so darker scenes have regained depth. Color Checker measurements confirm the improvement: most errors are below 2. That means the picture is very well set up for watching regular TV and SDR films. It wasn't as smooth in HDR. There is no effective way to correct the EOTF curve, so the TV still interprets a film's brightness somewhat on its own. It brightens parts of the picture and can dim the brightest elements depending on the scene and the behaviour of the local dimming. Calibration could not eliminate this. This is also reflected in the Color Checker results, where many errors remain around 3–4 and a few exceed 7. So the result in SDR is really very good, but in HDR we must accept that the TV adds its own interpretation of brightness to the image.

For the past two years digital picture processing has been one of Hisense's strengths, and the UR9S is no exception. The manufacturer uses the Hi-View AI Engine RGB processor, which in practice is built on the well-known MediaTek Pentonic 800 platform, previously used, among others, in the U8Q model. The TV handles upscaling lower-resolution material to 4K very well, and copes with low-bitrate content where compression artefacts are common. Thanks to a feature called "Smooth and Gradient Picture", the image remains detailed without appearing over-sharpened or artificially smoothed. When watching regular broadcast TV or older, lower-quality material, the UR9S can get a surprising amount out of them. In terms of digital picture processing, this is one of the most refined LCD TVs we've had the chance to test.

The handling of lower-quality material is fairly mediocre on the Hisense U7S. The Pentonic 700 chipset used here does not cope particularly well with strong compression artefacts. The menu includes a "Smooth and Gradient Image" function, but its performance leaves much to be desired. At the low setting tonal transitions show little improvement, although at least the image does not suffer. The medium and high settings still do not remove obvious banding between shades, and they begin to blur details; in our test material even parts of characters' faces disappeared. Interestingly, film grain remains untouched at every level. If you do use this feature, stick to the low setting. Its current behaviour needs refinement, but that is mainly down to the chipset used here.

Upscaling to 4K performs much better. Lower-resolution content gains in legibility, edges are well reproduced, and fine elements look sharp. That does not mean it recovers details that were never in the recording, but the TV makes good use of what it receives from the source. Another plus is that it does not crop the image edges, even with an SD signal.

The Hisense UR9S is one of the first televisions on the market with a 4K panel and a 170 Hz refresh rate. In the larger sizes, 75 and 85 inches, this goes up to 180 Hz. However, such a high refresh rate will be useful mainly to owners of very high-performance PCs. Most films and TV series are still watched at 24 fps, and sports broadcasts at 50 fps, so for everyday use panel response time and the operation of the motion smoothing are more important. In that respect the UR9S performs very well. Panel smearing is minimal, as confirmed by our UFO test. Moving objects do not leave a pronounced trail, so the picture remains clear even in fast scenes.

Motion handling on the Hisense U7S is decent thanks to the 144 Hz refresh rate. For films there is also a motion smoother with adjustable judder and blur reduction. You can therefore keep a more cinematic motion or increase smoothness if jerky camera pans bother you. The high refresh rate is also useful for sports and gaming, but unfortunately it does not solve the panel's biggest problem.

That problem is pixel response time. Fast-moving objects leave long, clearly visible trails, as our UFO test shows. It looks worst on dark backgrounds, where the trail behind the object is particularly pronounced. So motion can be smooth, but the moving object itself loses sharpness, and that difference on the U7S is fairly easy to notice.

Hisense UR9S is very well prepared for gaming. All three HDMI ports are HDMI 2.1 and offer the full 48 Gb/s bandwidth. The TV supports 4K at 170 Hz, and on larger screen sizes even 180 Hz. It also includes VRR, ALLM, NVIDIA G-Sync and AMD FreeSync, so in terms of basic features there is little to criticise. PC gamers can additionally enable DLG mode. After switching the resolution to Full HD the refresh rate can increase to as much as 330 Hz. That's probably an option for a relatively small group of users, but it shows how much headroom the panel has. Hisense has also added a Game Bar that lets you quickly change key settings, check the refresh rate or enable an on-screen crosshair and minimap zoom.

The biggest drawback remains the lack of a properly working HGiG. The TV still uses its own tone mapping, which makes configuring HDR on a console a bit more difficult. In our case values around 1500 to 2000 nits worked best, but it's worth checking which setting keeps all the detail in the brightest parts of the image.

The Hisense U7S has a lot to offer gamers. You get two HDMI 2.1 ports and support for 120 Hz at Full HD, 1440p, and 4K, so modern consoles’ capabilities are well used. When connected to a PC you can use 144 Hz at 4K or switch the resolution to Full HD and run 240 Hz. So there’s a wide choice, although it’s worth remembering the motion smearing mentioned earlier, which the high refresh rate does not eliminate. VRR and ALLM are also present. The first helps prevent tearing when frame rates in a game change. The second automatically switches the TV into game mode, so you don’t have to dig through the menu each time. VRR works from 48 to 240 Hz, with the highest refresh rate available in Full HD. Xbox users can also play in Dolby Vision, including at 120 Hz. Importantly, this format does not introduce significant input lag here. The Game Bar also looks very good. It’s easy to read, visually appealing, and lets you quickly check what signal the TV is receiving. There are also handy gaming settings at your fingertips, including shadow brightening. If it’s hard to spot an opponent in a dark game, you can improve visibility without digging through the entire menu.

Our biggest complaints concern HGiG. Hisense continues to do its own tone mapping, which makes setting HDR on the console confusing. You adjust a checkerboard test pattern and the TV continuously adapts how it looks. As a result, the moment the pattern disappears does not correctly indicate the screen’s brightness limit, and it’s easy to set the value too high. For this model it’s better to set the target HDR peak brightness on the console to about 900 to 1000 nits, rather than relying on the configurator.
