Xiaomi S Pro 2026 vs TCL P7L / P79L

When it comes to HDR quality, the Xiaomi S Pro 2026 is undoubtedly a very bright television. On our synthetic measurement patterns, we were able to achieve peak brightness of around 1400 nits. This result is not only very good but quite spectacular, considering the price of this model. However, as we always say, our editorial team values measurements and the viewing experience of content that people watch on a daily basis – from movies to series. So let’s analyse how Xiaomi performs with film material. The result is, unfortunately, quite mixed. When very bright scenes appear on screen, the S Pro 2026 truly shows its full capabilities and can achieve a real 800-1000 nits on bright elements. Moreover, even smaller objects can "burn" the eyes – in scenes from the movie Sicario 2, small metallic parts of the helicopter were really vivid. The problem is – and here the story comes full circle, returning to our contrast assessment – that in such scenes, we can’t count on absolutely cinematic black. In our opinion, this compromise is too significant; the high visibility of details in bright sections should not come at the expense of such a substantial drop in blacks. And even though the HDR effect can create a stunning impression here, it’s important to remember that when very challenging, mixed scenes appear on screen, we may feel a slight disappointment. Precisely the one we mentioned in the previous paragraph regarding issues with dimming in HDR mode. As a consolation, it’s worth adding that the S Pro 2026 is equipped with an additional PFS filter (similar in function to a QLED layer), which effectively broadens the colour gamut coverage. As a result, measurements showed DCI-P3 coverage reaching 94%. This gives us confidence that in most colourful scenes, the image will look rich and properly saturated.

The biggest limitation of the TCL P7L in HDR is simply brightness. The TV doesn't have much 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 dynamics, is closer to good SDR than to what brighter models show. That doesn't mean the P7L completely fails at HDR; the issue is mainly a lack of sufficient backlight power. Looking at colours, the situation is a bit better. The TV covers roughly 91% of the DCI‑P3 gamut and about 68% of the wide BT.2020 space, so for its price class the colour range is quite decent. TCL markets this model as QLED, although the nature of the solution used is closer to a PFS phosphor‑based backlight than a classic quantum dot layer. What matters most to the viewer is the effect: more saturated colours are on offer.

Of course, all our measurements were conducted in "Film" mode, which is typically the best and most faithful choice we get straight after taking the TV out of the box. And to put it bluntly: while this is the best mode, it is still very far from perfect. Above all, the TV has a clear tendency to give the picture a cool, blueish tint – this is due to poorly set colour balance. Additionally, there is the issue of how the S Pro 2026 manages its brightness straight out of the box, which results in an over-saturated image. These two flaws contribute to really significant colourimetric errors (Delta E). In HDR content, they could double exceed our expected error scale of "10" (i.e. reaching values close to 20). Just to remind you – the threshold of perceivable error by the human eye is a Delta E value of around 3. Results at the level of 20 mean that the image significantly deviates from what the director intended.

In Film mode the TCL P7L performs quite decently without major tweaks, especially with ordinary SDR material. The white balance is relatively even, although as brightness increases there’s a slight rise in red and blue and a bit too little green. That doesn’t create a strongly visible colour cast 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 particularly bother during normal viewing. We have more remarks about the gamma response. In the darkest parts of the image the TV drives it noticeably above the reference, so some shadow detail may be a little too dim. The curve then settles and for much of the range it’s close to the intended targets. As a result SDR generally looks natural, but in dark scenes the P7L can lose some subtlety.

In HDR the factory setup is less precise. As brightness increases the excess blue becomes more pronounced, so the picture can look cooler than it should. The number of larger colour deviations also rises, especially in brighter colours. The EOTF curve itself is handled fairly conservatively, with the TV showing the image darker than the reference over much of the range. For such an inexpensive model, the factory Film mode settings are not bad.

So how does the S Pro 2026 perform after our calibration process? We must admit that after calibration, the TV becomes a really enjoyable device for watching everyday content. As you can see in the charts, in HD (SDR) material, both white balance and gamma values have been brought to nearly perfection. Most importantly, colourimetric errors have become practically invisible to the human eye. In this scenario, the S Pro 2026 is simply a great TV that, after professional calibration, can provide a lot of joy from viewing. However, it is worth noting clearly – our efforts did little to help in 4K HDR mode. Despite the calibration, the TV still interprets the image quite strongly in its "own way," which is clearly evident in the measurement of the EOTF curve (brightness tracking). It's a bit of a shame because it shows that the problem lies not with the panel itself, but with the software. Poorly refined image management algorithms in HDR content can, unfortunately, rule this TV out for many more discerning users.

After calibration the TCL P7L can produce 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 evident in the colour measurements, as most errors have fallen significantly and in everyday viewing it’s hard to notice any major inaccuracies. Films, series, YouTube and regular TV therefore look more natural, without unnecessary warmth or a cool tint. For a model at this price point the SDR result is really very good.

In HDR the situation becomes more complicated. Calibration improved the white balance and corrected some deviations, but here the panel’s limitations become increasingly apparent. The P7L has relatively limited brightness and can’t sustain appropriate luminance for more saturated colours, so some errors remain even after careful tuning. In other words, settings can improve how the TV interprets the signal, but you can’t overcome its physical capabilities. That’s why calibration is most worthwhile for SDR on this model.

Let's start with the issue we raised in the previous paragraph: can a TV even fix the problem of terrible tonal transitions in dark scenes? Theoretically yes – in the menu, we find a feature with the promising name "Colour Contour Removal." Well, "theoretically." Unfortunately, in practice, this setting – regardless of which of the three power levels is chosen – yielded absolutely no real results. So we are dealing with a feature that practically only exists in the menu. Moving on to the quality of upscaling (scaling from a lower resolution to 4K), unfortunately, we have more bad news for you. The S Pro 2026 handles this task very poorly. Interestingly, the phenomenon of "overscan" (slight image cropping) is not a major issue here. The problem is that the TV simply shows a very raw, unprocessed image. Its attempt to boost the signal to a higher resolution looks simply dull and lacks any "intelligent" enhancement. There's no denying it – the entire digital image processing is the true Achilles' heel of this model.

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 doesn't remove all banding completely, but it can noticeably reduce posterisation and make trickier gradients look more natural. In this price segment that's a genuinely pleasant surprise.

The upscaling itself also looks good. Lower-resolution material is upscaled properly, without excessive sharpening or adding artificial edges around objects. Of course the P7L won't turn a very poor source into a 4K-quality picture, but for regular TV the result is simply solid. For a model at this price point there are few major complaints to make.

On paper, the specifications of the S Pro 2026 look impressive. The television is equipped with a native 144 Hz panel, capable of displaying images at up to 288 Hz in a dedicated gaming mode. These are incredible results, but what we were most interested in, in the context of everyday use, was how the TV handles motion blur and how the picture looks at 120 Hz. After all, this is the frequency used today by consoles such as the PlayStation 5, Xbox Series X/S, and it is desirable for sports fans. Generally, the panel "holds up". The matrix is quick enough to meet these challenges, and objects displayed at a native smoothness of 120 Hz are rendered correctly. When it comes to software, the TV is equipped with motion smoothing technology, but with a key caveat – it only works for input signals up to 60 Hz. This means it's mainly suitable for traditional TV, movies, and series. With it, we can adjust the smoothness of the picture to our own preferences – ranging from a very smooth, "theatrical" approach, to setting the slider at "zero" and maintaining a fully cinematic character.

TCL P7L uses a native 60 Hz panel 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 noticeable judder, but it doesn't deliver the smoothness typical of true 120 Hz panels.

For gamers, the Xiaomi S Pro 2026 is on paper an almost perfect proposition. It has been equipped with two HDMI 2.1 ports, which allow us to unlock (although these options are somewhat hidden in the menu) the full suite of features: ALLM, VRR, and, crucially, the ability to operate in 4K at 144 Hz. This last feature should particularly please owners of powerful PCs. The TV also has something resembling a gamer panel – and while it’s hard to call it a full-fledged "Gamebar," it does its job by displaying key information. It’s just a shame that in its default form, it covers a relatively large part of the screen.

The biggest problem we have with this model, however, concerns how the S Pro 2026 handles games in HDR mode. To put it bluntly: it doesn’t handle it well. Due to the poorly implemented HGiG feature (the HDR tone mapping standard for games), during the initial HDR calibration on the console, it’s very easy to "blow out" the image. If someone is unaware of this software flaw and follows the on-screen instructions, they will simply set the picture incorrectly, with burnt-out details in bright areas. Another significant issue is the Dolby Vision mode for games. While it works, it generates such a high input lag that it becomes noticeable in dynamic titles. (You can check all our lag measurements in the paragraph below). In summary: Generally, this is a really very good screen for gamers, but with one small caveat. We would rather avoid HDR mode on it – unless we decide to manually set the brightness slider on the console "by eye," completely ignoring the tips from the console's pictogram.

For such an inexpensive TV, the P7L has quite a lot to offer gamers. It has ALLM, VRR and Dolby Vision in games, and TCL also includes its Game Bar, where you can quickly check 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 part comes when you give up 4K. At that resolution the TV runs at up to 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 the difference in smoothness is genuinely noticeable, 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. Still, it's precisely these extra modes that make the P7L perform really well for gaming.
