XIAOMI S Mini 2026 (55"-75") 60Hz vs TCL P7L / P79L

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 biggest limitation of the TCL P7L in HDR is simply brightness. The TV doesn't have a large luminance headroom, so strong highlights, sunlight, or small light sources can't clearly "pop" out of the image. As a result, even well-produced HDR material looks fairly restrained and in terms of dynamic range is closer to good SDR than to what brighter models show. That doesn't mean the P7L can't handle HDR at all — the issue is mainly a lack of sufficient backlight power.

Looking at color, the situation is a bit better. The TV covers about 91% of the DCI-P3 gamut and about 68% of the wider BT.2020 color space, so for its price class the color range is quite decent. TCL markets this model as QLED, though the nature of the solution used is closer to a PFS phosphor-based backlight than a classic quantum-dot layer. What matters most to viewers, however, is the result: more saturated colors are available.

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.

In Film mode the TCL P7L performs fairly well without major adjustments, especially with typical SDR material. The white balance is relatively even, although as brightness increases there is a slight rise in red and blue and a bit of a shortage of green. This does not produce a strongly noticeable tint and most colors remain close to their reference points. The ColorChecker confirms this, with a large portion of errors falling below a level that would notably bother viewers during normal watching. We have more concerns about the gamma response. In the darkest parts of the image the TV runs it noticeably above the reference, so some shadow detail can be a little too dimmed. The curve then settles and for much of the range it is close to the intended target. As a result SDR generally looks natural, but in dark scenes the P7L can lose some subtlety. In HDR the factory setting is less precise. As brightness increases an excess of blue becomes more pronounced, making the image look cooler than it should. The number of larger color deviations also grows, particularly in brighter hues. The EOTF curve itself is handled fairly conservatively, with the TV showing the image darker than the reference over a large portion of the range. For a budget model, however, the factory Film mode settings are not bad.

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.

After calibration, the TCL P7L can deliver a really pleasant picture, especially with classic SDR material. We managed to very effectively even out the white balance, and the gamma curve now tracks close to the target value of 2.4. You can also see this in the color measurements, as most errors dropped noticeably, and in everyday viewing it's hard to find any strongly visible inaccuracies. Movies, series, YouTube, or regular TV therefore look more natural, without unnecessary warming or a cool cast. For a model in this price range, the result in SDR is really very good.

With HDR the situation gets more complicated. Calibration helped improve the white balance and tidy up some deviations, but here the panel's limitations become increasingly apparent. The P7L has relatively low brightness and can't maintain appropriate luminance for more saturated colors, so some errors remain even after careful tuning. In other words, settings can improve how the TV interprets the signal, but they can't overcome its physical capabilities. That's why calibration makes the most sense for this model primarily with SDR.

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.

In this regard the TCL P7L performs surprisingly well, especially for such an inexpensive TV. The tonal transition smoothing feature, which in many budget models does little or almost nothing, actually manages to improve the picture here. It doesn't remove all banding completely, but it can noticeably reduce posterization and make trickier gradients look more natural. At this price point that's a genuinely pleasant surprise.

Upscaling itself also performs well. Lower-resolution material is scaled correctly, without excessive sharpening or adding artificial outlines around objects. Of course the P7L won't turn a very poor source into 4K-quality footage, but for regular TV the result is simply solid. For a model in this class there is little to criticize.

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.

The TCL P7L uses a panel with a native 60 Hz refresh rate at 4K resolution, and that's how it should be treated in everyday use. For movies the TV mainly offers frame interpolation, so it can smooth motion and reduce the typical judder, but it does not deliver the smoothness of true 120 Hz panels.

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.

For such an inexpensive TV, the P7L has quite a lot to offer gamers. It has ALLM, VRR, Dolby Vision for gaming, and TCL adds its Game Bar, which lets you quickly view key information or change some settings without leaving the game. Not everything is perfect, though, because HGiG doesn't work here as it should, but at this price point it's hard to complain much about the feature set. The most interesting thing starts when you give up on 4K. At that resolution the TV runs at a maximum of 60 Hz, but at 1440p and 1080p it can already display at 120 Hz. And that's not just a spec-sheet curiosity. In fast-paced games that support that frame rate you can really notice the difference in smoothness, so if you care more about smoother motion than maximum image sharpness, that mode can make a lot of sense. Of course that doesn't make the P7L a true 120 Hz TV. Even so, it's precisely those extra modes that make the P7L perform really well for gaming.
