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 TV reaches around 1,000 nits of brightness without much trouble, allowing it to show a very pronounced HDR effect in bright scenes. The sun, reflections and brightly lit parts of the image can be really intense and at times almost striking in their brightness. It is a bit different in dark scenes, though. Very small light sources surrounded by black are displayed at much lower brightness, so they lack that pinpoint intensity seen on the best TVs. That said, this is not unusual for a Mini LED. The local dimming algorithm reduces the backlight to preserve the deepest possible blacks, which in such scenes matter more than a few extra nits.

HDR colours

Colour reproduction also performs well. Xiaomi markets the S Mini 2026 as a QLED TV, although the solution used here is effectively based on a PFS phosphor. The result is what matters, and it's quite good. Our measured coverage of the DCI-P3 gamut was about 94%, while in the much wider BT.2020 colour space it was about 74%. This means the TV can reproduce most colours used in HDR films with suitably high saturation. Its limitations are most visible with very intense shades of green, where the colour gamut starts to run out.

The biggest limitation of the TCL P7L in HDR is simply brightness. The TV does not have much luminance headroom, so strong highlights, the sun or small light sources can't clearly 'pop' out of the picture. As a result, even well-produced HDR material looks fairly restrained and, in terms of dynamics, is closer to good SDR than to what brighter models show. That does not mean the P7L completely fails at HDR. The issue is primarily a lack of backlight power.

Looking at colours, the situation is a little better. The TV covers around 91% of the DCI-P3 gamut and about 68% of the wide BT.2020 colour space, so for this price class the colour range is quite respectable. TCL markets this model as QLED, although the nature of the solution used is closer to backlighting that uses a PFS phosphor than to a classic quantum-dot layer. What matters most to the viewer, however, is the effect: more saturated colours are on offer.

We tested the Xiaomi S Mini 2026 in sizes from 55 to 75 inches in Film mode, which offered the most accurate colours compared with the other presets. That did not mean the picture was correctly set up straight away. In our sample the white balance was clearly shifted towards warmer tones. There was too little blue and too much red, so whites and greys had a slightly warm tint. The TV also tended to brighten darker parts of the image too much. This was due to the gamma, which instead of staying around 2.4 dropped in places to about 2.0. As a result there was more detail visible in the shadows, but the image lost some depth. The factory settings were therefore not bad, but there was still some way to go to achieve accurate image reproduction.

In Film mode the TCL P7L performs quite respectably without major changes to the settings, particularly with ordinary SDR material. White balance is relatively even, though as brightness increases there is a slight rise in red and blue and a touch too little green. This does not, however, produce a strongly visible tint and most colours remain close to their reference points. The Colour Checker confirms this, with a large portion of errors falling below the level that should be particularly noticeable during normal viewing. We have more reservations about the gamma response. In the darkest parts of the image the TV runs it noticeably above the reference value, so some shadow detail can be a little too subdued. The characteristic then calms down and across much of the range it is close to the intended behaviour. As a result SDR generally looks natural, but in dark scenes the P7L can lose some subtlety.

In HDR the factory calibration is less precise. As brightness increases the excess of blue becomes more pronounced, which can make the image look cooler than it should. The number of larger colour deviations also grows, particularly in brighter hues. As for the EOTF curve itself, it is handled fairly conservatively, with the TV showing the image darker than the reference across much of the range. For such an inexpensive model, the factory Film mode settings are not bad.

Contrary to appearances, the Xiaomi S Mini 2026 responds quite well to calibration. After our adjustments the white balance was noticeably improved and the picture stopped leaning towards overly warm tones. With SDR material the effect is really good, and the TV can render such content very accurately; it is hard to fault it on colour reproduction. We applied similar corrections for HDR, though not everything could be fixed there. Colours look better than on the factory settings, but the TV still tends to display the image a little brighter than it should. This is visible in the EOTF curve, which sits above the reference value. In practice this means some HDR scenes are brighter than the creators intended. It is a quirk of this TV and we have no influence over it.

After calibration the TCL P7L can deliver a genuinely pleasant picture, especially with conventional SDR material. We managed to even out the white balance very well, and the gamma curve now tracks close to the target value of 2.4. This is also reflected in the colour measurements: most errors have fallen noticeably, and in everyday viewing it is hard to point to any obvious inaccuracies. Films, series, YouTube and ordinary broadcast TV therefore look more natural, without unnecessary warmth or a cool tint. For a model in this price bracket the SDR performance is really very good.

With HDR the situation becomes 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 cannot maintain adequate luminance for more saturated colours, so some errors remain even after careful tuning. In other words, settings can improve the way the TV interprets the signal, but they cannot overcome its physical limits. That is why calibration makes most sense for this model primarily in SDR.

Digital image processing in the Xiaomi S Mini 2026 is handled by the MT5896 processor. Unfortunately, in this respect the TV is rather mediocre. Low-resolution content is not scaled very well, and its limitations quickly become apparent on a large screen. The picture looks quite digital, and the TV cannot bring out many extra details. Additionally, overscan cannot be turned off for low-resolution content. The situation is even worse when it comes to smoothing posterisation. On the smaller models there is not even a dedicated setting to reduce visible banding between similar shades. So if such imperfections are already present in the source material, Xiaomi essentially does not mask them.

In this respect the TCL P7L performs surprisingly well, especially for such an inexpensive TV. The banding-reduction feature, which in many budget models does little or nothing, actually manages to improve the picture here. It does not remove all banding entirely, but it can noticeably reduce posterisation and make more challenging 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 over-sharpening or adding artificial outlines around objects. Of course the P7L won’t turn a very poor source into a 4K-quality image, but for regular TV the result is simply solid. For a model in this class there is little to criticise.

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

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 reduced. It is not at a level that completely ruins the perception of motion, but in dynamic scenes you can tell the panel is not 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 regarded in everyday use. When watching films the TV mainly offers frame interpolation, so it can smooth motion and reduce the characteristic judder, but it does not deliver the fluidity typical of true 120 Hz panels.

In larger sizes the Xiaomi S Mini 2026 is a much more interesting proposition for gamers. The panel natively runs at up to 144 Hz, so when connected to a PC you can use the high refresh rate even in 4K. At lower resolutions the TV can go even further, reaching up to 288 Hz. It also supports ALLM, automatic switching to game mode, and a Game Bar with the most important settings to hand. Of course, the TV has two full-bandwidth HDMI 2.1 ports. In terms of smoothness the difference compared with the 55 to 75-inch versions is therefore significant and especially noticeable with a PC or console. Not everything works perfectly, though. As with the smaller variants, we have reservations about the implementation of HGiG. The HDR setup screens on the PS5 and Xbox do not accurately match the TV's real capabilities, so if you set your console 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 also includes its Game Bar, which lets you quickly check the 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 about the feature set. The most interesting part starts when you give up 4K. At that resolution the TV runs at up to 60 Hz, but at 1440p and 1080p it can display at 120 Hz. And that’s not just a line in the specs. In fast-paced games that support that frame rate you can really notice the improvement in smoothness, so if you value smoother motion more than maximum image detail, that mode can make a lot of sense. Of course, that doesn’t turn the P7L into a proper 120 Hz TV. Even so, those extra modes are exactly what make the P7L perform very well for gaming.
