LG QNED91T6A vs Xiaomi S Pro 2026

As befits a MiniLED television, LG QNED91T easily surpasses the magical barrier of 1000 nits on the luminance chart. In scenes where light played a key role, the effect was truly decent. For instance, 1000 nits in the first scene of "Life of Pi" is an impressive value, and the 600 nits achieved in the third and fifth scenes allowed one to feel the true magic of HDR. However, problems arise with very small light elements on the screen, such as the moon, street lamps, or lights. A value around 100 nits - to put it bluntly - is disappointing, as these elements are dark enough to be barely visible. The television deserves praise for covering 96% of the DCI-P3 colour gamut and 75% of BT.2020. LG QNED91T leaves us with very mixed feelings, mainly due to the very aggressive dimming algorithms, which, while effectively eliminating the halo effect, negatively impact the brightness of smaller elements.

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 generate peak brightness of around 1400 nits. This result is not only very good but truly spectacular, considering the price of this model. However, as we always emphasise, for our editorial team, measurements and the experiences from the content viewed on a daily basis - from films and series - are more important. So let's analyse how the Xiaomi performs with film material. The result is, unfortunately, quite mixed. When very bright scenes appear on screen, the S Pro 2026 really shows its full potential and can achieve a real 800-1000 nits in bright elements. Moreover, even smaller objects can "burn" the eyes - in scenes from the film Sicario 2, small metal elements of the helicopter were truly vivid. The problem is that - and here the story comes full circle back to our contrast assessment - in such scenes we cannot count on absolutely cinematic black. In our opinion, this compromise is too great; high visibility of details in bright areas should not come at the cost of such a significant boost to black levels. And although the HDR effect itself can make a stunning impression here, it is essential to remember that when very challenging, mixed scenes appear on screen, we might feel a slight disappointment. Exactly the one we mentioned in the previous paragraph regarding issues with dimming in HDR mode. As a consolation, it is worth adding that the S Pro 2026 has been 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 up to 94%. This gives us confidence that in most colourful scenes, the image will appear rich and appropriately saturated.

All our tests are conducted in the best picture mode on each television. In this case, as usual, it is the Filmmaker mode. The name of the mode suggests ideal colour reproduction; however, there were noticeable deviations from the correct image here. Our unit, in terms of white balance, displayed quite a strong dip in blue hues - both in SDR and 4K HDR content - which resulted in a distinct yellowing of the image, visible in comparison scenes from the film with Tom Cruise. As we mentioned earlier, QNED91T has certain tendencies to brighten the screen. This is confirmed by gamma, which is quite significantly below the reference value of 2.4. Meanwhile, the EOTF curve, responsible for brightness in 4K content, showed some issues with the television's dimming in the darkest areas, which we could observe in the paragraph describing the quality of the HDR effect. Although the Filmmaker mode is quite a good "out-of-the-box" mode, it too requires some adjustments.

Of course, all our measurements were carried out in "Film" mode, which is typically the best and most accurate choice we get straight out of the box. It needs to be said plainly: although it is the best mode, it is still very far from ideal. Firstly, the television has a clear tendency to impart a cool, bluish tint to the image – this is due to a poorly set white balance. Additionally, there is the issue of how the S Pro 2026 manages its brightness straight out of the box, which results in an overly vivid image. These two flaws contribute to truly significant colourimetric errors (Delta E). In HDR content, they were able to exceed our anticipated error scale of "10" by twofold (meaning values close to 20). As a reminder – the threshold for perceivable error by the human eye is a Delta E value of around 3. Results at the level of 20 indicate that the image significantly deviates from what the director intended.

LG offers advanced calibration tools in its televisions such as 65QNED91T6A, which we utilised. When it comes to white balance, we were able to significantly correct it in SDR content. The picture mode in 4K HDR quality posed greater challenges, which, although still not perfect, looks significantly better than before calibration. Errors on the Color Checker palette and colour gamut are much smaller than in the factory settings. Regarding brightness characteristics, gamma for HD content is practically ideal, with a slight exception at the end of the graph. However, the television had the most trouble with brightness in 4K HDR content. Analyzing the EOTF characteristics in films, we observed that the television manipulates brightness quite heavily, which we could see in previous tests. Brightness is significantly boosted compared to the graph in the static test, and the television lights up certain scenes to the point that some smaller elements lose detail. This is unfortunately caused by the average backlight zone management algorithm in this model. Nevertheless, calibration yields quite good results, especially when it comes to the precise reproduction of colours.

So how does the S Pro 2026 perform after our calibration procedure? We have to admit that after calibration, the television becomes a really very pleasant device for watching everyday content. As you can see in the graphs, in HD (SDR) materials, both white balance and gamma values have been brought to nearly perfection. Most importantly, colourimetric errors have become practically unnoticeable to the human eye. In this scenario, the S Pro 2026 is simply an excellent television that, after professional calibration, can provide a lot of enjoyment from watching. However, it is worth clearly noting – our efforts have not helped much in 4K HDR mode. Despite the calibration, the television still interprets the image quite strongly "in its own way," which is clearly visible in the measurement of the EOTF curve (brightness tracking). It’s a bit of a shame, as it shows that the problem lies not in the panel itself, but in the software. Underdeveloped image management algorithms in HDR content can, unfortunately, rule out this television for many more discerning users.

When it comes to tonal transitions in lower quality materials, the television offers a well-known feature from LG televisions - "Smooth Gradation". We can control it in three levels: low, medium, and high. We recommend using the medium option, as it does a good job of removing tonal transitions without causing noticeable problems with the removal of object structure or other artefacts.

As for image scaling (upscaling), LG's Alpha processor performs quite well in this regard. The image appears very plastic, with slight aliasing on some elements, which does not significantly affect the quality. It looks really okay, and the overall effect is very satisfactory.

Let's start with the issue we raised in the previous paragraph: can the television actually fix the problem of dreadful 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, in practice, only exists in the menu. Moving on to the quality of upscaling (scaling the image from a lower resolution to 4K), unfortunately, we have more bad news for you. The S Pro 2026 performs very poorly at this task. Interestingly, the phenomenon of "overscan" (slight cropping of the image) is not a major issue here. The fact is that the television simply displays a very raw, unprocessed image. Its attempt to upscale the signal to a higher resolution looks simply lacklustre and lacks any form of "intelligent" improvement. There is no denying it – the entire digital image processing is the real Achilles' heel of this model.

The television has a refresh rate of 120 Hz, which should satisfy most users in terms of motion smoothness. Additionally, QNED91T is equipped with the TruMotion feature, which allows for smoother image display in films. Within this feature, we can adjust the "De-Judder" and "De-Blur" sliders. The "De-Judder" slider is responsible for reducing judder in films, which is particularly useful when playing content with a lower frame rate, while "De-Blur" helps to reduce blur in fast scenes, which is important for sports or dynamic shots.

On paper, the S Pro 2026 specification looks impressive. The television is equipped with a native 144 Hz panel, with the ability to display images at up to 288 Hz in a dedicated gaming mode. These are amazing results, but what interested us most, in the context of everyday use, was how the television handles motion blur and how the image looks at 120 Hz. After all, this is the frequency used by consoles like the PlayStation 5 and Xbox Series X/S, and it is desired by sports fans. Generally, the panel "holds up". The matrix is sufficiently fast to meet these challenges, and objects displayed at native 120Hz fluidity are shown correctly. As for the software, the television is equipped with motion smoothing technology; however, with a key caveat – it works only for input signals up to 60 Hz. This means it is primarily suitable for traditional television, films, and series. Thanks to this, we can adjust the fluidity of the image to our own preferences – from a very smooth, "theatrical" approach to setting the slider to "zero" and maintaining a fully cinematic character.

The LG 65QNED91T6A television is equipped with HDMI 2.1 ports with full bandwidth of 48 Gb/s, providing full support for all the standards needed for gaming on modern consoles. We can count on variable refresh rate (VRR) support and automatic low latency mode (ALLM). This ensures smooth gameplay without delays.

Thanks to support for all popular HDR standards in games, such as HGiG and Dolby Vision, we can fully utilise the potential of the PS5 and XBOX One consoles. The television also handles lower resolutions than 4K without any issues, so even older consoles look good on it. The Game Bar makes it easy to access gaming-related settings, allowing us to quickly and intuitively adjust picture parameters and features for gamers. Additionally, the QNED91T offers the NVIDIA GeForce Now feature, which allows us to play in the cloud without needing a console. However, it should be noted that this solution is quite costly and somewhat falls short of the Xbox Game Pass, which is available only on Samsung televisions.

QNED91T LG is an excellent choice for both less experienced and more advanced gamers looking for a versatile television for gaming.

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

The biggest issue 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 at all. Due to the television having a poorly implemented HGiG feature (the HDR tone mapping standard for games), it is very easy to "overexpose" the image during initial HDR calibration on the console. If someone is unaware of this software flaw and follows the on-screen instructions, they will simply set the image incorrectly, resulting in burnt-out details in the bright areas. Another major problem is the Dolby Vision mode for games. While it does work, 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 speaking, this is a really very good screen for gamers, but with one small caveat. We would rather avoid using HDR mode on it – unless we decide to manually set the brightness bar on the console "by eye", completely ignoring the instructions from the console’s pictogram.
