XIAOMI S Mini 2026 (85"-98") 144Hz vs Hisense UR8S

The larger versions of the Xiaomi S Mini 2026 offer very similar HDR performance. Peak brightness reaches around 1,000 nits, which is a very solid result for a TV in this price bracket. It's most noticeable in bright scenes, where large, heavily lit areas of the picture can look really impressive. The TV has enough brightness headroom that HDR isn't limited to just a slightly brighter image. However, very small pinpoint highlights on an almost completely black background fare worse. In such cases the local dimming system significantly reduces their brightness to avoid lighting adjacent parts of the image and to preserve good blacks. As a result, small reflections or single lamps don't have the same intensity as in much more expensive models. This is typical behaviour for Mini LED TVs and it's hard to treat it as something unique to Xiaomi.

HDR colours

The colour performance is similarly comparable. Although the manufacturer uses the term QLED, the expanded colour gamut here comes from the PFS phosphor. In our measurements the TV covered about 94% of the DCI-P3 space and about 74% of the much more demanding BT.2020. In practice this yields well-saturated colours in most HDR material and it's hard to point to obvious gaps. Limitations appear mainly with the most saturated shades of green, which the TV can no longer reproduce fully.

UR8S is a higher-end Mini-LED, so you could expect plenty of brightness. Indeed, on a synthetic test pattern peak brightness reached about 2200 nits. That’s a very good result, but as always what the TV does in normal film scenes matters much more. Here the results are a bit more mixed. In bright scenes with lots of light on screen, the UR8S can deliver very strong HDR. Brightness then gets up to around 1500 nits, so the image is very intense and has a lot of punch. It’s worse with small bright elements on a dark background. The TV noticeably dims them to preserve deep blacks and avoid excessive blooming. As a result, things like single stars or small specular highlights can be only around 200 nits. And here HDR is no longer as impressive. So the local dimming algorithm works effectively, but it comes at a cost — sometimes it sacrifices the brightness of small details too much in favour of contrast.

Colours

For RGB Mini-LED TVs, colours should be evaluated a little differently than usual. If we look only at the panel’s capabilities, the UR8S performs excellently. We measured about 94% coverage of BT.2020 and virtually full DCI-P3. Those are among the highest figures currently seen in LCD TVs, and this is where the potential of the RGB backlight is most apparent. The problem is that this potential isn’t always used in real scenes. When we ran the same measurements on patterns overlaid with a film-like background, saturation of some colours started to fall noticeably. Individual zones can’t always control the three RGB components with the same precision when the scene becomes more complex. It’s most noticeable with blue and magenta. On simple test patches they can look very strong, but in tougher scenes samples of those colours clearly shrink. In other words, the UR8S has huge potential, but the TV can’t always take full advantage of it in every scene.

On the larger versions of the Xiaomi S Mini 2026, Film mode performs best, although even here the out-of-the-box settings are not without flaws. In SDR the white balance was noticeably warm due to an excess of red. In HDR the opposite was true, with too much blue and too little red, which made the image cooler. Additionally, both the gamma response in SDR and the EOTF curve in HDR sat slightly above the reference values. In practice this resulted in a slightly brightened image, particularly in the midtones. It wasn't a major fault, but with more demanding material you could see that the image wasn't reproduced entirely in line with the filmmakers' intent.

For evaluating the factory colours we used Filmmaker mode, which is supposed to show the image as close as possible to how the content was prepared. And if you look at the white balance alone, the UR8S performs quite well. There’s no strong tint that immediately jumps out, although as brightness increases a bit too much blue and red start to appear, with a corresponding lack of green. Colour errors are therefore visible in measurements, but the image itself doesn’t look bad.

We have much bigger reservations about how the UR8S manages image brightness. In SDR the gamma stays around 1.9–2.0 for most of the range instead of the target 2.4. In practice this simply means the image is too bright, especially in the midtones. Shadows are lifted too much, so the picture loses some depth. A similar tendency is visible in HDR. The EOTF curve sits above the reference value for a large part of the range, so the UR8S again brightens the image more than it should. This isn’t a case of the TV lacking brightness, because it has plenty, but of how it manages that brightness. As a result, HDR material can look very striking, but not always exactly as it should.

After calibration we mainly managed to even out the white balance, so colours look much more natural in both SDR and HDR. We also improved the gamma response, so SDR content is no longer unnecessarily brightened and stays closer to reference values. The only larger issue remaining is in HDR. Xiaomi still controls brightness a little too aggressively and renders some scenes brighter than it should. This is less noticeable on the larger models than on the 55–75-inch versions, but the EOTF curve still runs slightly above the reference. In practice HDR is therefore slightly brightened, even though colour reproduction after calibration is already very good.

Hisense offers quite a lot of calibration options, and in SDR you can achieve a really good result with them. After adjustment the white balance is practically even across the whole range, and colour errors fall to very low values. The UR8S can be set very precisely here. HDR looks a little different. The white balance can also be noticeably improved, although at the highest brightness levels larger deviations start to appear. Most interesting, however, is the behaviour of the EOTF curve. Even after correctly setting it on test patterns, the UR8S can still interpret brightness in its own way when watching films. Depending on the scene, parts of the picture are slightly brightened and others darkened compared with how they should look. This shows that the algorithms controlling the backlight have quite a large influence on the final image. Calibration therefore allows colours to be improved very well, but we are not able to completely 'turn off' the way the UR8S manages brightness in HDR.

The larger variants of the Xiaomi S Mini 2026 also use the MT5896 processor and perform similarly in terms of digital image processing. Upscaling isn't a strong suit of this model. Low-resolution material is upscaled to 4K in a fairly basic way and it doesn't recover fine detail as well as more refined TVs. The 85- and 98-inch versions do include a feature intended to reduce posterisation, but it's barely effective. When it's switched on it's hard to notice any real improvement, so in scenes with visible colour banding the TV still does little to address it.

The big plus of the UR8S is its use of the MediaTek Pentonic 800 processor, and digital image processing is one of this model’s stronger points. The TV handles smoothing tonal transitions very well, especially with poorer-quality material. The feature responsible for this effect works effectively without overprocessing the picture. Even on a medium setting it can noticeably reduce visible banding and artefacts without heavily blurring details. Upscaling itself also performs very well. Lower-resolution content is displayed cleanly, edges look natural, and the image isn’t over-sharpened. The UR8S simply copes very well with weaker signals, and in that respect it’s one of its clear strengths.

The biggest difference between the various sizes of the Xiaomi S Mini 2026 is the panel's refresh rate. The 55–75-inch variants use a 60 Hz panel, which in practice means noticeably less smooth motion than the larger versions. This is easiest to spot when watching sport, fast-moving scenes or gaming, where the picture isn't as smooth and clear in motion.

The UR8S is equipped with a panel that has a native 180 Hz refresh rate, so right away it offers very strong potential for smooth motion. The panel itself performs really well, although some limitations typical of VA panels are still visible. Smearing is relatively low for this type of screen, but during faster motion, especially on darker backgrounds, it can still be noticed, particularly if you compare the same image to OLED TVs.

The smaller versions of the Xiaomi S Mini 2026 unfortunately have a big limitation for gamers — a 60 Hz panel. In 4K we’re therefore limited to 60 fps and can’t fully take advantage of the PS5 or Xbox Series X. You can run 120 Hz, but only after dropping the resolution to 1080p or 1440p. Other than that, it’s pretty reasonable. The TV supports ALLM and automatically switches to game mode when it detects a console. There’s also a Game Bar where you can quickly check the main gaming settings. Our biggest reservation is HGiG. The HDR calibration screens on the PS5 and Xbox don’t match the TV’s actual capabilities. If you set HDR exactly according to them, some of the brightest elements can simply be blown out.

In terms of gamer features the UR8S stacks up really well. The TV supports virtually everything you'd expect from a modern console or PC display. It has ALLM, VRR, and 4K at 120 Hz. There's also Dolby Vision in game mode, so when using, for example, an Xbox Series X you don't have to give up that HDR format. PC gamers get even more options. The panel can run at 4K and 180 Hz, and dropping to Full HD can push the refresh rate as high as 330 Hz. There's also a Game Bar that lets you quickly view key info and change gaming-related settings. The only real shortcoming is a proper implementation of HGiG. When enabled, the TV still interferes with HDR brightness mapping, so we don't get the effect intended by that standard. Apart from that, the UR8S is very well equipped for both consoles and a powerful PC.
