Xiaomi S Pro 2026 vs LG QNED80A6A (VA)

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.

Let's talk now about how this TV shines. If you’re expecting dazzling light effects, we need to cool your enthusiasm. The LG QNED80A is a moderately bright television. Our measurements in most film scenes indicated values around 350-400 nits. That’s not enough to speak of a full, cinematic HDR experience and the feeling of that famous “high dynamic range” that flagship products offer. However, brightness is not everything. Although the QNED80A is not a “light monster,” it makes up for it in another key category: colours. This is where PFS technology comes into play, which LG marketers hide under the name QNED/NanoCell. With this trick, the TV offers a significantly wider colour palette than classic LCD constructions. In our tests, the coverage of the cinematic DCI-P3 palette reached a solid 93-94%. What does that mean for you? That even at lower brightness, when watching films in HDR, the colours will be vibrant, deep, and properly saturated. The image is not washed out but juicy, which is a significant advantage in this price range.

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.

It might seem that since the QNED80A is one model, it should offer the same picture regardless of the version. However, practice shows something completely different. Analyzing the variant with the VA panel in the best factory setting – that is, in Filmmaker Mode – we noticed a specific characteristic. This TV "out of the box" delivers a picture with a clear dominance of red and a deficiency of blue. Overall, it is very warm, almost hot. Many users might describe it as an "overly cinematic" picture, leaning towards sepia. Additionally, there is the issue of gamma curve – the TV has a tendency to slightly and artificially brighten scenes (gamma is too low), which causes the picture to lose some of its plasticity. The good news is that these are not panel errors, but merely software issues. As always in our tests, we performed professional calibration, which completely eliminated these drawbacks, restoring natural white balance and correct saturation.

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.

Was it worth spending time on calibration? Definitely yes. We managed to tame the initial, overly warm white balance and, most importantly, correct the gamma curve. The television stopped artificially brightening scenes, resulting in a deeper image. The biggest gains are visible in SDR content, such as when watching regular television, YouTube, or playing games without HDR. Here, the QNED80A shows its class – colour reproduction errors (DeltaE) fell below a value of 2. In technical terms, this means the errors are essentially invisible to the human eye. The image in everyday use has simply become very attractive, natural, and correct. The difficulties start with HDR content. Although we managed to improve the white balance, the EOTF curve (responsible for brightness at various levels) shows that the television still "interprets" the image in its own way. This results from the nature of the edge-lit backlighting with local dimming and the fact that LG gives the calibrator very little control over this parameter. In short: the television struggles to hide its hardware shortcomings, sometimes ignoring our commands. Nevertheless, the final image is significantly more accurate and pleasant to view than the factory settings, even if it still lacks a bit compared to studio perfection.

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 category, the QNED80A turns out to be a true "dark horse". It's a fantastic, affordable television for those who often watch lower quality content – for example, from traditional cable TV. The processor used here handles upscaling incredibly well, enhancing low resolutions to native 4K. The image after processing is natural, smooth, and most importantly – it is not overly jagged or artificially sharpened. In the menu, we also find a dedicated option for smoothing tonal transitions in low-quality content. This feature works really effectively, eliminating the annoying "banding" of colours during heavy video compression. However, we must remain vigilant. Remember, we are not dealing with the top-tier processor known from flagship OLED models. In more challenging scenes, the system might struggle and introduce minor artefacts or distortions. Nevertheless, it's definitely worth giving this feature a chance, because in the majority of cases, the quality improvement is visible to the naked eye.

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.

We move on to a topic that may be crucial for many. Unfortunately, here we must point out the biggest "Achilles' heel" of the QNED80A model. This television is equipped with a panel that has a native refresh rate of 60Hz. There’s no denying it – at this price, we were hoping for more as we know that Chinese manufacturers can offer 120Hz screens for similar money. Due to this parameter, dynamic scenes in sports or fast-paced games are not the strongest point of this screen. Fortunately, LG has equipped the television with a proven smoothing system called TruMotion. It works quite well with film material (24 frames). We suggest playing around with the De-Judder slider – from our experience, setting it in the range of 2-4 provides the best compromise: motion becomes smoother, yet still looks natural, without the artificial "television theatre" effect.

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.

Since we've already established that the QNED80A is a 60Hz TV, we must say it straight: we won't be gaming here at 120 frames per second at any resolution. Does this disqualify the device in the eyes of gamers? Not necessarily, especially for those "casual" players. LG decided to sweeten this technical limitation by packing in quite a few useful features. We have support for VRR (Variable Refresh Rate) in the range of 48-60Hz and an automatic game mode ALLM, which instantly reduces input lag upon detecting a console. We manage all of this via a very convenient, purple Game Optimizer menu (Player Panel), which has become LG's hallmark. The manufacturer deserves big points for consistency regarding HDR. Although the TV does not support Dolby Vision in games on Xbox consoles, LG adds a well-implemented HGiG standard. Thanks to this, even on a screen with moderate brightness, playing in HDR is clear, and the details in shadows and highlights are accurately rendered, rather than being "clipped".
