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 1,000 nits, which is a very solid result for a TV at this price point. This is most apparent in bright scenes, where large, heavily lit areas of the image can look really striking. The TV has enough brightness headroom that HDR isn't reduced to just a slightly brighter image. However, very small pinpoint highlights on an almost completely black background perform worse. In those situations the local dimming system significantly reduces their brightness to avoid illuminating adjacent image areas and to preserve deep blacks. As a result, small specular highlights or single lamps don't have the same intensity as in much more expensive designs. This is, however, typical behavior for Mini LED TVs and is hard to treat as something unique to Xiaomi.

HDR colors

Color performance is similarly comparable. Although the manufacturer uses the term QLED, the expanded color gamut here is achieved by a PFS phosphor. In our measurements the TV covered about 94% of the DCI-P3 color space and about 74% of the much more demanding BT.2020. In practice this yields well-saturated colors in most HDR material and it's hard to point to obvious shortcomings. Limitations appear mainly with the most saturated shades of green, which the TV can no longer 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 the peak brightness reached around 2200 nits. That's a very good result, but as always what matters more is what the TV does in normal film scenes. Here the results are a bit more uneven. In bright scenes with 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 a lot of punch. It's worse with small bright elements on a dark background. The TV noticeably dims them to maintain good blacks and avoid excessive blooming. As a result, things like single stars or tiny 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 simply sacrifices the brightness of small details too much in favor of contrast.

Colors

With RGB Mini-LED TVs, colors should be evaluated a bit differently than usual. If we look solely at the panel's capabilities, the UR8S performs great. We measured about 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 RGB backlighting is most apparent. The problem is that this potential isn't always used in real scenes. When we ran the same measurements on patterns with an overlaid film background, the saturation of some colors dropped noticeably. Individual zones can't always control the three RGB components as precisely when the scene becomes more complex. This is most noticeable with blue and magenta. In simple test patterns they can look very strong, but in tougher scenes samples of those colors clearly shrink. So the UR8S has enormous potential, but the TV can't always make full use of it.

In the larger versions of the Xiaomi S Mini 2026, Film mode performs best, although the factory settings here are not without flaws. In SDR the white balance was noticeably warm due to an excess of red. In HDR the situation was the opposite: there was too much blue and too little red, which made the image cooler. Additionally, both the gamma curve in SDR and the EOTF curve in HDR were slightly above the reference values. In practice this resulted in a slightly brighter image, especially in the midtones. It wasn't a major fault, but with more demanding content you could tell the image wasn't reproduced exactly as the creators intended.

For evaluating out-of-the-box colors we used Filmmaker mode, which is supposed to show the image as close as possible to how the material was intended. Looking at white balance alone, the UR8S does quite well. There is no strong color cast that immediately jumps out, although as brightness increases a bit too much blue and red appear while green becomes deficient. Color errors therefore show up in measurements, but the image itself does not look bad.

We have far bigger reservations about how the UR8S manages image brightness. In SDR the gamma stays around 1.9 to 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 image loses some depth. A similar trend is visible in HDR. The EOTF curve sits above the reference value for a large portion of the range, so the UR8S again brightens the image more than it should. This is not a matter of the TV lacking brightness; it has plenty of it. The issue is how it manages that brightness. As a result, HDR material can look very striking, but not always exactly as it should.

After calibration, we were mainly able to even out the white balance, so colors in both SDR and HDR look much more natural. We also improved the gamma curve, so SDR content is no longer unnecessarily bright and stays closer to reference values. The only significant remaining issue is in HDR. Xiaomi still controls brightness a bit too aggressively and renders some scenes brighter than it should. That is less noticeable on larger screen 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 color reproduction after calibration already looks very good.

Hisense offers quite a few calibration options, and in SDR you can achieve a really good result with them. After calibration, the white balance is practically uniform across the entire range, and color errors drop to very low values. The UR8S can be adjusted very precisely here. HDR looks a bit different. The white balance itself can also be noticeably improved, although at the highest brightness levels larger deviations start to appear. What's most interesting, however, is the behavior of the EOTF curve. Even after it is properly set on test patterns, the UR8S can still interpret brightness its own way during movie playback. Depending on the scene, parts of the image are slightly brightened while others are darkened compared to how they should look. This shows that the algorithms responsible for backlight control have a fairly large impact on the final image. So calibration can greatly improve colors, but we can't completely "turn off" the way the UR8S manages brightness in HDR.

Larger variants of the Xiaomi S Mini 2026 also use the MT5896 processor and perform similarly in terms of digital image processing. Upscaling is not a strong suit of this model. Low-resolution content is upscaled to 4K in a fairly basic way and it does not recover fine detail as well as more refined TVs. The 85- and 98-inch versions do include a feature intended to reduce posterization, but its effectiveness is very limited. With it turned on it's hard to notice any real improvement, so in scenes with visible color banding the TV still does little to address it.

A major advantage of the UR8S is its MediaTek Pentonic 800 processor, and digital image processing is one of this model’s strengths. The TV handles smoothing tonal transitions very well, especially with lower-quality sources. The feature responsible for this effect works effectively without overly interfering with the picture. Even at the medium setting it can noticeably reduce visible banding and unevenness without heavily blurring details. Upscaling also performs very well. Lower-resolution content is displayed cleanly, edges look natural, and the image isn’t overly 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 models use a 60 Hz panel, which in practice means noticeably less motion smoothness than the larger versions. It's easiest to notice this when watching sports, fast-moving scenes, or playing games, where the picture isn't as smooth or clear in motion.

The UR8S is equipped with a panel that has a native 180 Hz refresh rate, so it already offers great potential for smooth motion. The panel itself performs really well, though some limitations typical of VA panels are still visible. Smearing is relatively low 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'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. Otherwise it's fairly reasonable. The TV supports ALLM and automatically switches to Game Mode when it detects a console. There's also a Game Bar that lets you quickly view the most important gaming settings. Our biggest issue is with 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 highlights may simply be clipped.

In terms of gamer features the UR8S performs really well. The TV supports practically everything you’d expect from a modern console or PC display. It offers ALLM, VRR, and 4K at 120 Hz. It also supports Dolby Vision in game mode, so when using 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/180 Hz, and dropping to Full HD can raise the refresh rate up to 330 Hz. There’s also a Game Bar that lets you quickly view key information and change gaming-related settings. The only clear shortcoming is a proper implementation of HGiG. With it enabled the TV still interferes with HDR brightness mapping, so we don’t get the effect intended by that standard. Aside from that, the UR8S is very well prepared for both consoles and a powerful PC.
