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

The larger versions of the Xiaomi S Mini 2026 offer very similar HDR capabilities. Peak brightness reaches around 1000 nits, which for a TV in this price bracket is a very solid result. This is most apparent in bright scenes, where large, strongly lit parts of the picture can look truly impressive. The TV has enough brightness headroom that HDR does not amount to merely a slightly brighter image. Very small points of light appearing on an almost completely black background fare worse. In such cases the local dimming system significantly limits their brightness so as not to illuminate neighbouring parts of the picture and to preserve deep blacks. As a result, small highlights or single lamps do not have the same intensity as in much more expensive models. This, however, is typical behaviour for Mini LED TVs and hard to treat as something unique to Xiaomi.

HDR colours

The issue of colours is similarly close. Although the manufacturer uses the term QLED, the expansion of the colour gamut here is achieved by a PFS phosphor. In our measurements the TV covered around 94% of the DCI-P3 colour space and about 74% of the much more demanding BT.2020. In practice this delivers well-saturated colours in most HDR material and it is hard to point to any obvious shortcomings. Limitations appear mainly with the most saturated shades of green, which the TV is no longer able to reproduce in full.

UR8S is a slightly higher-end Mini-LED, so you could expect a lot in terms of brightness. And indeed, on a synthetic test pattern peak brightness reached around 2200 nits. That’s a very good result, but as always what’s much more important is what the TV does in normal film scenes. Here the results are a bit more uneven. In bright scenes, where there’s a lot of light on screen, the UR8S can deliver really strong HDR. Brightness then reaches about 1500 nits, so the image is very intense and has plenty of punch. It’s worse with small bright elements on a dark background. The TV clearly dims them to keep good blacks and to prevent excessive bloom. As a result things like single stars or tiny reflections can be only around 200 nits. And here HDR is no longer as impressive. So you can see that the local dimming algorithm works effectively, but it also has its cost: sometimes it simply sacrifices the brightness of small details in favour of contrast.

Colours

With RGB Mini-LED TVs colours should be judged a little differently than usual. If we look solely at the panel’s native capabilities, the UR8S performs excellently. We measured around 94% coverage of BT.2020 and practically full DCI-P3. These are among the highest values currently found in LCD TVs and this is where the potential of the RGB backlight is most obvious. The problem is that this potential is not always realised in real scenes. When we ran the same measurements on test patterns with a film background applied, saturation of some colours began to fall noticeably. Individual zones are not always able to control the three RGB components so precisely when the scene becomes more complex. This is most visible with blue and magenta. On simple test patterns they can look very strong, but in more demanding scenes samples of those colours visibly shrink. So the UR8S’s capabilities are enormous, it’s just that the TV cannot fully make use of them in every scene.

In the larger versions of the Xiaomi S Mini 2026 Film mode performs best, although the factory settings here are not without faults. In SDR the white balance was noticeably warm due to an excess of red. In HDR it was the opposite: there was too much blue and not enough red, which made the image cooler. Moreover, both the gamma response in SDR and the EOTF curve in HDR were slightly above the reference values. In practice this produced a slightly brighter image, particularly in the mid-tones. It was not a major fault, but with more demanding material you could notice that the image was not reproduced entirely as the creators intended.

For assessing the out-of-the-box colours we used Filmmaker mode, which is intended to show an image that is as close as possible to how the material was prepared. Looking at the white balance alone, the UR8S performs quite well. There is no strong tint that immediately jumps out, although as brightness increases a little too much blue and red start to appear, with a simultaneous shortfall of green. Colour errors therefore show up in measurements, but the image itself does not look bad. We have far greater reservations about how the UR8S manages picture brightness. In SDR the gamma sits around 1.9–2.0 for most of the range instead of the target 2.4. In practice this simply means the picture is too bright, especially in the midtones. Shadows are lifted too much, causing the image to lose some depth. A similar tendency is visible in HDR. The EOTF curve is above the reference value for a large part of its range, so the UR8S again brightens the image more than it should. This is not due to a lack of brightness — the TV has plenty — but to the way it manages that brightness. As a result, HDR content can look very striking, but not always precisely 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 the SDR picture is no longer unnecessarily brightened and holds closer to the reference values. The only major issue remaining is in HDR. Xiaomi still manages brightness a little too aggressively and renders some scenes brighter than it should. It looks better on larger sizes than on the 55–75 inch models, 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 provides plenty of calibration options and, in SDR, these can yield a very good result. After calibration, the white balance is practically even across the entire range, and colour errors fall to very low values. The UR8S can be adjusted very precisely here. HDR is somewhat different. The white balance itself can also be noticeably improved, although at the highest brightness levels larger deviations begin to appear. The most interesting aspect, however, is the behaviour of the EOTF curve. Even after it has been correctly set on test patterns, the UR8S still tends to interpret brightness in its own way when watching films. Depending on the scene, parts of the image are slightly brightened while others are dimmed relative to how they should appear. This shows that the algorithms controlling the local dimming have a significant influence on the final image. Calibration therefore allows colours to be improved very effectively, but we are not able to completely 'turn off' the way the UR8S manages brightness in HDR.

The larger Xiaomi S Mini 2026 variants also use the MT5896 processor and perform similarly in terms of digital image processing. Upscaling is not one of this model's strengths. Low-resolution content is upscaled to 4K in a fairly basic way, and there is not as effective retrieval of fine detail as in more refined televisions. The 85 and 98 inch versions do include a feature intended to reduce posterisation, but its effectiveness is very limited. After switching it on it is hard to notice any real improvement, so the TV still does little to address visible banding between colours.

A big plus of the UR8S is the 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 lower-quality content. The feature responsible for this effect works effectively without overprocessing the picture. Even on the medium setting it can noticeably reduce visible banding and unevenness without heavily blurring details. Upscaling itself also performs very well. Lower-resolution content is displayed cleanly, edges look natural, and the image is not overly sharpened. The UR8S simply copes very well with a weaker signal, and in this respect it is one of its most notable strengths.

The biggest difference between the various sizes of the Xiaomi S Mini 2026 concerns the panel's refresh rate. The 55 to 75-inch variants use a 60 Hz panel, which in practice results in noticeably less smooth motion than the larger versions. This is most apparent when watching sport, fast-paced scenes or gaming, where the picture is not as smooth and sharp in motion.

The UR8S is equipped with a panel with a native 180 Hz refresh rate, so right from the start it offers excellent motion handling. The panel itself performs really well here, although some limitations typical of VA panels are still visible. Motion blur is relatively minor for this type of screen, but with faster motion (especially on darker backgrounds) it can still be noticed, particularly when compared with the same image on OLED TVs.

Unfortunately, the smaller versions of the Xiaomi S Mini 2026 have a significant limitation for gamers: a 60 Hz panel. In 4K we are therefore limited to 60 fps and cannot fully take advantage of the PS5 or Xbox Series X. It is possible to run 120 Hz, but only after dropping the resolution to 1080p or 1440p. Apart from that, it’s all fairly sensible. The TV supports ALLM and automatically switches to game mode when it detects a console. There is also a Game Bar that lets you quickly check the most important gaming settings. Our biggest reservation concerns HGiG. The HDR calibration screens on the PS5 and Xbox do not match the TV’s actual capabilities. If you set HDR exactly according to them, some of the brightest elements may simply be blown out.

In terms of gamer features the UR8S performs really well. The TV supports practically everything you can expect from a modern console or PC display. It offers ALLM, VRR and 4K at 120 Hz. There is also Dolby Vision in Game Mode, so when using, for example, the Xbox Series X you do not have to give up that HDR format. PC gamers get even more options. The panel can run at 4K at 180 Hz, and dropping to Full HD can raise the refresh rate to as much as 330 Hz. There is also a Game Bar that lets you quickly check key information and change gaming-related settings. The only clear omission is a correct implementation of HGiG. With it enabled the TV still alters HDR brightness mapping, so we do not get the effect intended by that standard. Aside from that, the UR8S is very well prepared for both consoles and a powerful PC.
