Samsung QN900D Neo QLED 8K vs Xiaomi S Pro 2026

The Samsung QN900D easily showcases its high capabilities in light production during synthetic tests – 1400 nits is truly an impressive result. It also demonstrated these capabilities in the first scene of the movie "Life of Pi," where we see a brilliant burst of the rising sun. However, due to issues with the dimming algorithm, some problems can be observed here. In the test scenes from "Sicario 2" and the second scene from "Life of Pi," these values are not as high, averaging around 500-600 nits. While this may not be the worst result among Mini LED TVs, more could be expected given the price of the television. Nevertheless, the television deserves praise for covering a wide colour gamut of DCP P3 at 96%. Although there are technologies offering higher values, this result is still satisfactory.

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 QN900D television offers a Filmmaker mode that is designed to watch movies in the most natural way possible; however, this mode is not without its flaws. For HD content, the white balance shows a dominance of red and blue, which causes the image to shift towards pink hues. In contrast, for 4K HDR content, the situation is reversed – the reduction of blue and red levels results in warmer scenes and a shift towards yellow tones. This is confirmed by Color Checker tests, which clearly show that the colour samples veer in that direction.

When it comes to brightness and the associated contrast, the gamma is significantly distorted. The biggest issue is a noticeable jump at the beginning of the curve, indicating that dark details are overly brightened, causing the image to lose depth in the darkest areas - this is due to local dimming. For 4K HDR materials, the EOTF curve looks quite good, but it remains below the reference level, impacting the overall dynamics of the image.

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.

After calibration, the Filmmaker mode can truly be called worthy of its name. The white balance for both HD and 4K HDR content has significantly improved, resulting in colours that are more natural and consistent. The image has gained in realism, with pink hues in HD content effectively eliminated, as well as the yellow haze in 4K HDR content. Thanks to the calibration, the television now offers much better colour reproduction, positively impacting the viewing experience.

When it comes to brightness, the situation with gamma is now the opposite – a clear drop is visible at the beginning of the graph, making the darkest details harder to discern. The EOTF curve for 4K HDR content has remained largely unchanged and is still below the reference level, indicating that the television still struggles to maintain adequate brightness. This is related to the aggressive dimming algorithm that affects the overall brightness of the image. You can see how the television fights to maintain high brightness or perfect black.

Despite the limitations associated with local dimming, the Samsung QN900D has improved in colour reproduction quality, as confirmed by the Color Checker test results – the colour samples are now much closer to the references, making the image more natural and pleasant to the eye.

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.

The fluidity of tonal transitions in lower-quality materials looks fantastic – the Noise Reduction feature very effectively smooths out tonal transitions while getting rid of film grain. Although the removal of grain isn't always desirable, the overall final effect is very aesthetically pleasing, especially for those who prefer a cleaner image.

When it comes to upscaling, or image scaling, QN900D shows the tremendous capabilities of the new processor with AI technology. Photos and materials in lower resolution are scaled while retaining many details – for example, a photo with a model looks amazing, free of unnecessary jagged edges, and the branches in the background are not overly serrated.

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.

Samsung QN900D is currently the fastest television in the world – literally. A refresh rate of 240 Hz in 4K resolution is an amazing value that PC gamers will surely appreciate. As for movie fans, they won't be disappointed either – Samsung offers a 10-level scale in the picture clarity settings, allowing users to adjust the image. We can choose whether the television should provide a smoother, theatrical effect at the highest settings, or a more cinematic one, with a visible frame, at the lowest settings.

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.

Samsung QN900D is a television that offers excellent compatibility with consoles and a range of features that gamers will appreciate. It has 4 HDMI 2.1 ports, although unfortunately without the full bandwidth of 48 Gb/s. Nonetheless, for the average user, this is more than sufficient. Additionally, the television supports Auto Low Latency Mode (ALLM) and Variable Refresh Rate (VRR), which means smoother images and no screen tearing during dynamic gameplay. The G-Sync and FreeSync technologies are also noteworthy, providing optimal compatibility with consoles and computers equipped with the appropriate graphics cards, minimising stuttering effects and ensuring a smooth picture.

One of the unique features available only in Samsung televisions is the Xbox Game Pass app, which allows for game streaming without the need for a console. This is a very convenient solution that lets you enjoy your favourite games without having to purchase additional hardware. Furthermore, the QN900D has Game Bar – a special panel that enables quick access to gaming-related settings, making game mode setup quick and intuitive.

Another interesting feature is the Auto Motion Plus Game function, which is a special motion smoothing mode that can increase the frame rate (works up to a maximum of 4K@60Hz). Importantly, this does not cause a significant increase in input lag, allowing players to enjoy both greater image fluidity. All these features make the Samsung QN900D an excellent choice for those looking for a gaming television with the highest possible parameters.

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.
