XIAOMI S Mini 2026 (85"-98") 144Hz vs Samsung R85H / R86H

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.

If it’s about brightness, the R85H performs really well. In most of our test scenes the TV reaches around 800 to 900 nits, and with larger bright elements it can break 1000 nits. These aren't, of course, levels on par with the most expensive Mini-LEDs, but they're more than enough for watching movies and TV series in HDR, and the effect can be quite noticeable. The problem shows up again in more demanding scenes where there's a small bright element on a very dark background. Here the TV can significantly reduce its brightness so it doesn't illuminate too much of the screen. In our measurements such small highlights dropped to around 200 to 250 nits, so you can see that a limited number of local dimming zones combined with the specific behavior of the algorithm has its consequences. Fortunately, it's not something that bothers you all the time. In typical mixed HDR scenes the R85H looks good and can deliver appropriate image dynamics. You just can't expect the same punch from very small points of light as you get with TVs that have many more zones or with OLEDs.

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.

In Filmmaker mode our R85H sample performed adequately in SDR, but a few things immediately showed up in the measurements. In the white balance, as brightness increased more red crept in while blue decreased. As a result, the brighter parts of the image had a slightly too warm tint. On top of that, gamma only held to the target value at the start. It then gradually fell, making most of the image a bit too bright. The combination of the two also affected colors — errors grew especially in the brighter, more saturated samples. It didn’t look bad, but for Filmmaker mode we expected a bit more accuracy. Interestingly, in HDR our unit handled things noticeably better. White balance was much more even and, for most of the range, the individual RGB components stayed close together. Only in the brightest areas did red begin to fall short, causing the white point to shift slightly. The EOTF curve looked very good, tracking the target luminance values across almost the entire range. That doesn’t mean HDR colors were perfect. The ColorChecker still shows some deviations, particularly in some of the more saturated hues, but the errors are clearly smaller than in SDR.

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.

After calibration the R85H shows it has impressive color reproduction capabilities. It performed best in SDR, where the white balance was brought almost perfectly into line and the gamma stays very close to the target across most of the range. That also translated into very low errors in the ColorChecker, so there's really little to fault here. HDR also shows a clear improvement, although some issues can't be corrected as well. At peak brightness the character of the backlight itself starts to show and the individual components of the white balance begin to diverge. The same goes for the most saturated colors, which don't always land exactly where they should. Despite these limitations, overall the image is significantly more accurate than on the factory settings, and the biggest difference is clearly in SDR. However, there's one thing calibration can't fix. With highly saturated elements, color can subtly bleed onto adjacent bright parts of the image. It's easiest to notice this on white, which can pick up a slight tint from a neighboring hue. It doesn't occur in every scene, but when the content is demanding the effect can be visible. This is more a characteristic of the way the RGB backlight works than an issue with picture settings.

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.

In the R85H, image processing is handled by the Micro RGB AI Processor. The name is new, but in terms of upscaling lower-quality content, the TV’s behavior remains very similar to what Samsung has shown before. And that’s not a bad thing, since the company has handled this aspect quite well for years. Low-resolution material is displayed cleanly, edges don’t become overly soft, and the TV doesn’t try to artificially extract details at any cost. The result is simply balanced, and with regular TV or older recordings the R85H performs as you would expect from a Samsung at this level. The only minor drawback is overscan, which can’t be completely turned off at the lowest resolutions. A separate issue is the additional processing of weaker sources. The R85H can smooth posterization and tidy up heavily compressed footage a bit, but it’s worth stressing that it does so relatively aggressively. At stronger "noise reduction" settings it starts removing not only compression artifacts but also fine details and natural film grain. It’s best to use it only when the material actually needs it.

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.

R85H has a 144 Hz panel, so motion is really smooth here. Just remember that the extra hertz above 120 will mainly be used when connected to a PC, so in this category we don't treat them as a particular advantage. For movies and TV, what's more important is that the panel is fast enough to provide access to an advanced motion-smoothing feature, "Motion Clarity", which lets us set motion from more film-like to very smooth. The panel's response time is a bit weaker. Because this is a VA panel, fast-moving objects can leave a slight trail. On bright backgrounds that's not very noticeable, but the darker the scene, the more visible the smearing becomes. That's a typical characteristic of this type of panel, and it's easiest to spot in dark scenes.

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.

Samsung has been steadily expanding its gamer-focused features for several years, and the R85H really lacks nothing important in that area. The TV supports 4K at 120 Hz, VRR and ALLM, so you can easily take advantage of the capabilities of the PlayStation 5 or Xbox Series X. HGiG also works correctly, so with the right HDR settings on the console games retain proper brightness and you don't unnecessarily lose detail in the brightest parts of the image. The only major omission is Dolby Vision Gaming, which Samsung doesn't support on any of its TVs.

Game Bar is also very useful, a handy menu you can bring up without leaving the game. You can quickly check the frame rate, VRR operation, or change the most important picture-related settings. Samsung also adds a few less obvious features, such as the ability to change the aspect ratio or Game Motion Plus, which can further smooth games running at 30 or 60 fps. Of course, this comes at the cost of higher input lag (around 55 ms), but for slower-paced titles it may be an interesting option for some players.
