XIAOMI S Mini 2026 (55"-75") 60Hz vs Hisense U7S / U77SE

When it comes to HDR, the capabilities of the Xiaomi S Mini 2026 are really good, especially given the segment this model belongs to. The set reaches roughly 1,000 nits of brightness without much trouble, allowing it to deliver a very pronounced HDR effect in bright scenes. Sun highlights, reflections, and brightly lit parts of the image can be very intense and at times almost blindingly bright. It’s a little different in dark scenes, though. Very small light sources surrounded by black are shown at significantly lower brightness, so they lack the point-like intensity seen in the best TVs. This is not unusual for a Mini LED. The local dimming algorithm limits the backlight to keep blacks as deep as possible, which in those scenes matters more than a few extra nits.

HDR Colors

Color reproduction also performs well. Xiaomi markets the S Mini 2026 as a QLED TV, although the solution used here is practically based on a PFS phosphor. What matters most is the result, and it’s quite good. Our measurements showed about 94% coverage of the DCI-P3 gamut, while in the much wider BT.2020 space it was around 74%. That means the TV can reproduce most of the colors used in HDR films with suitably high saturation. Its limitations are most visible only with very saturated shades of green, where the color range starts to fall short.

The Hisense U7S has considerable HDR potential, but it can't use it 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's still enough for the sun or bright highlights to have a noticeable glow and to show an advantage over SDR material. When the TV needs to illuminate a larger portion of the image, it does quite well.

The problem appears with small lights 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 strongly light such a zone, it would also brighten the surrounding area along with the light. Hisense tries to avoid that and dims the entire zone. Black levels therefore look better, but a small bright object that should draw the eye also loses intensity. That's why in two tougher scenes we recorded only 297 and 154 nits. The difference is large: in one shot HDR can impress, and in the next small lights are noticeably muted. The U7S therefore prioritizes maintaining deep blacks, even at the expense of bright details. With this number of zones that's an understandable compromise, but it's worth remembering — the 1,100-nit peak tells us about the backlight's capability, not how brightly the TV will render every element of a film.

Colors

Hisense calls the U7S ULED, but that's a marketing name; the wider color gamut here comes from a PFS phosphor backlight. In our measurements the TV covered about 91% of DCI-P3 and 71% of BT.2020. Those are good results, although it falls short of the best screens on the market. The biggest shortfall is in green — the TV doesn't even reach the DCI-P3 target there, so the most saturated shades will be less intense than they should be. Most colors in HDR films and series, however, still look suitably rich. A positive is the repeatability of the results. Gamut coverage on test patterns and in film scenes is practically identical.

We tested the Xiaomi S Mini 2026 in 55–75-inch sizes in Film mode, which offered the most accurate colors compared with the other presets. That said, the picture wasn't perfectly set up out of the box. In our unit the white balance was clearly shifted toward warmer tones. There was too little blue and too much red, so whites and grays had a slightly warm tint. The TV also tended to brighten darker parts of the image too much. This came from the gamma, which instead of staying around 2.4 sometimes dropped to about 2.0. That made more shadow detail visible, but the picture lost some depth. The factory settings weren't bad, but they still needed tweaking to reproduce the image correctly.

The out-of-the-box colors on the Hisense U7S are decent, but there are a few things to improve. In SDR there's a red bias in the white balance, which makes the image too warm and in places slightly pink. You can notice this on faces and on bright, neutral surfaces. Gamma also runs below the reference, so the TV brightens the image, especially in darker areas. That makes shadow details easier to see, but the scene loses some of its depth.

In HDR the white balance is a bit more even, but not completely neutral; midtones lack blue, and the brightest areas lack red. A bigger problem is how brightness is reproduced. The EOTF curve shows that a large portion of midtones is being brightened, so the image looks brighter than the source material intends. Color Checker measurements also perform worse than in SDR: many errors are around 3 to 4, and individual ones reach as high as 8. Colors can therefore look attractive, but they are not always faithful to what we should be seeing. There's room for improvement, and we'll check how much can be corrected with calibration.

Contrary to appearances, the Xiaomi S Mini 2026 responds quite well to calibration. After our adjustments we were able to noticeably improve the white balance, and the picture stopped leaning too warm. With SDR content the result is really good, the TV can display such images very accurately, and it's hard to find major faults in its color reproduction. We applied similar corrections in HDR as well, though not everything could be fixed. Colors look better than at factory settings, but the TV still tends to render the image slightly brighter than it should. You can see this in the EOTF curve, which sits above the reference value. In practice this means some HDR scenes are brighter than the creators intended. This is a quirk of this TV and we can't do anything about it.

Calibration of the Hisense U7S helped most with SDR content. We managed to even out the white balance, so the previous warm cast is gone and whites and grays look neutral. Gamma is also now very close to the reference, and the TV no longer brightens the image unnecessarily, so darker scenes have regained depth. Color Checker measurements confirm the improvement: most errors fall below 2. That yields a really well-calibrated picture for regular TV and SDR movies. It didn't go as smoothly in HDR. The TV lacks an effective way to correct the EOTF curve, so Hisense still interprets the content's brightness a bit on its own. It brightens parts of the image and can dim the brightest elements depending on the scene and the local dimming behavior. Calibration couldn't eliminate this. It shows up in the Color Checker results as well, where many errors remain around 3–4 and individual ones exceed 7. So in SDR the result is very good, but in HDR we have to accept that the TV adds its own interpretation of brightness to the image.

Digital image processing in the Xiaomi S Mini 2026 is handled by the MT5896 processor. Unfortunately, in this respect the TV performs rather average. Low-resolution content is not upscaled very well, and its limitations become quickly apparent on a large screen. The image looks quite digital, and the TV can't extract many additional details from it. Additionally, you cannot disable overscan for low-resolution material. Things are even worse when it comes to smoothing posterization. On the smaller models there isn't even a dedicated feature to reduce the visible banding between similar shades. So if such imperfections are already present in the source material, Xiaomi effectively does not mask them.

The handling of lower-quality material on the Hisense U7S is fairly mediocre. The Pentonic 700 chipset used here doesn't cope well with the effects of heavy compression. The menu includes a "Smooth & Gradient" picture option, but its performance leaves much to be desired. At the low setting it's hard to notice any improvement in tonal transitions, although at least the image isn't degraded. The medium and high settings still don't remove visible banding between shades and begin to smear details; in our test clips even parts of characters' faces disappeared. Interestingly, film grain remains untouched at every level. If you use this feature, we'd stick with the low setting. Its current behavior needs refinement, but that's mainly down to the processor used. Upscaling to 4K performs much better. Lower-resolution footage gains clarity, edges are well reconstructed, and fine elements look crisp. That doesn't mean it can recover details that weren't in the recording, but the TV makes good use of what it gets from the source. Another plus is that it doesn't crop the image edges, even with an SD signal.

The smaller variants of the Xiaomi S Mini 2026 use a 60 Hz panel, and that's their biggest limitation when it comes to motion. For movies and TV series this isn't yet a major issue, because the TV has a classic motion smoothing for 24/30 fps content. So we can reduce the characteristic judder and adjust motion to our own preferences. Sports and other 50/60 Hz content fare worse, because there is no additional feature to improve smoothness. With that kind of material we are therefore limited by the panel itself.

In terms of motion blur the TV performs quite typically for a VA panel. Most trailing is visible behind objects moving on a dark background, while in brighter scenes the effect is noticeably smaller. It's not at a level that completely ruins motion perception, but in dynamic scenes you can tell the panel isn't among the fastest.

Motion handling on the Hisense U7S is pretty good thanks to the 144 Hz refresh rate. For movies we also have a motion smoothing feature that lets you adjust judder and blur reduction. You can therefore keep a more cinematic motion or increase smoothness if abrupt camera shifts bother you. In sports and games the high refresh rate is also useful, but unfortunately it doesn't solve this panel's biggest problem.

The culprit is pixel response time. Fast-moving objects leave long, noticeable trails, as our UFO test shows. It's worst on dark backgrounds, where the trail behind the object is especially pronounced. So motion can be smooth, but the moving object itself loses sharpness, and that difference on the U7S is fairly easy to notice.

In larger sizes the Xiaomi S Mini 2026 becomes a far more interesting option for gamers. The panel natively runs at up to 144 Hz, so when connected to a PC we can take advantage of the high refresh rate even in 4K. At lower resolutions the TV can go even further and reach up to 288 Hz. There’s also ALLM, automatic switching to game mode, and a Game Bar with the key settings at hand. Of course, the TV is equipped with two full-bandwidth HDMI 2.1 ports. In terms of smoothness, the difference compared to the 55 to 75 inch versions is therefore substantial and especially noticeable when using a PC or console. Not everything works perfectly, though. As with the smaller variants, we have reservations about the HGiG implementation. The HDR setup screens on the PS5 and Xbox don’t exactly match the TV’s real capabilities, so if you configure the consoles according to those prompts the brightest parts of the image can be blown out and lose some detail.

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.
