Xiaomi S Pro 2026 vs Samsung The Frame 2026 (LS03H)

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.

The Frame 2026 is a genuinely bright TV. Its peak brightness reaches around 650 nits and, importantly, it maintains similar levels regardless of the type of scene being displayed. It doesn’t really matter whether we’re watching a very bright full-screen image or just a small highlight occupying part of the screen. The backlight remains powerful, allowing bright parts of the image to stand out clearly.

This gives The Frame a solid foundation for HDR. Bright highlights can look impactful, and the picture doesn’t appear flat or overly dim. Unfortunately, there is a compromise. Without local dimming, the TV cannot darken the black areas surrounding very bright objects.

This is clearly visible in scenes 2 and 4 of our test procedure. Bright elements look impressive, but at the same time, the blacks around them become noticeably raised. As a result, the image loses some of its depth, especially when watching in a dark room. This is why The Frame performs best with HDR in bright and moderately bright scenes, where its high brightness works to its advantage. In darker scenes, the situation is quite the opposite.

Colours

The Frame also performs well when it comes to colour reproduction. As a QLED TV, it can display a wide colour gamut and produce rich, saturated colours. DCI-P3 coverage reaches around 94%, while BT.2020 comes in at around 72%. These are good results, and you can see the difference in actual content.

Colours look vivid without appearing washed out, particularly in bright and colourful scenes. Animations and other content with plenty of saturated colours can look really good on The Frame. With this type of material, the TV shows one of its stronger sides.

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.

For assessing the factory colour output we chose the Filmmaker Mode. If you’re encountering it for the first time, it’s a mode designed to reproduce a film or series as faithfully as possible. The TV then switches off most of the extra picture enhancement features, and the colours and luminance characteristics are intended to be as close as possible to what the creators of the material intended. And it must be admitted that The Frame 2026 performs really well in this respect straight out of the box. The biggest deviation is visible in the white balance. As brightness increases the blue starts to drop out and green increases slightly. As a result the picture shifts toward warmer tones. White is therefore not perfectly neutral, and in some scenes you can notice a slightly warmer cast.

The luminance response for both the gamma and EOTF curves looks good. Across most of the range they stay fairly close to the target, although in the darkest parts of the picture there is a larger deviation. In practice some details emerging from black may therefore be rendered a little more strongly. However, this is not an error that stands out during normal viewing. Overall Filmmaker Mode is a good starting point here. However the picture is a little too warm by default and not all hues land exactly where they should.

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.

After calibration we mainly managed to remove that warmer tint and better even out the white balance. We also smoothed the brightness response a little, which made the picture more neutral and predictable. There are, however, things calibration won't fix here. It's mainly the black behaviour, which stems from the backlight design and the lack of local dimming. In some scenes blacks will therefore still be slightly lifted and you simply have to accept that. It's more a characteristic of this model than something that can be fixed with the settings. HDR is also a limitation. Samsung doesn't allow full freedom when working with the widest colour gamut, so not all colours can be reproduced perfectly. In normal viewing it's probably hard to notice, but it's worth being aware of.

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.

As with many of Samsung’s newer TVs, this one also uses the NQ4 AI processor, only the older, second-generation version. And you have to admit it handles digital image processing quite well. Lower-resolution material is sharpened effectively, and after upscaling to 4K it still looks natural. The TV can also somewhat "tidy up" weaker sources, like older recordings or lower-quality broadcasts. That doesn't, of course, mean it will suddenly turn poor footage into 4K, but at closer viewing distances the difference compared with simpler models with weaker processors is easy to spot. Edges are clearer, and fine details don't get lost as much to signal compression.

Samsung also offers a few additional image-enhancing features, but as usual it's best to use them sparingly. At stronger settings, noise reduction can very effectively reduce posterization, but it also noticeably interferes with the image. The picture then simply starts to look very artificial, for example by heavily smoothing characters' faces. So it makes the most sense with really poor sources when various types of noise are seriously distracting.

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.

Samsung again used a panel with a maximum refresh rate of 144 Hz. Refresh rates up to 120 Hz primarily offer greater possibilities with material that contains a lot of motion. The TV can use additional motion-smoothing systems that can improve fluidity in sports and other fast-moving content. However, a high refresh rate alone does not solve everything. The Frame still uses a VA panel, which has a fairly slow response time, and consequently fairly pronounced motion blur. With rapidly moving objects, especially on a dark background, trails are easy to notice. There is also a slight doubling of edges, which can be visible even when additional motion-enhancement systems are switched off. We saw similar behaviour in last year's The Frame 2025, and it's a shame Samsung hasn't addressed this issue. The 144 Hz itself provides a good foundation, but the panel's response time still limits this TV.

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.

In terms of gaming features, The Frame is practically on a par with Samsung’s top televisions. When a console is connected the TV automatically switches to Game Mode thanks to ALLM, so we do not have to change settings manually each time. There is also VRR, which matches the screen refresh rate to the number of frames produced by the console or PC. This helps avoid the characteristic screen tearing when frame rates drop. The Frame of course supports 4K at 120 Hz, so you can take advantage of the capabilities of the PlayStation 5 or Xbox Series X in games that offer higher frame rates. HGiG also works correctly. With HDR properly configured on the console, the TV does not try to brighten the picture further on its own, so bright effects in games are displayed as they should be. Samsung also includes a Game Bar. It is a handy menu you can bring up without leaving the game. There you can check VRR operation and the current frame rate, and quickly change the most important gaming-related settings. With a PC the possibilities are even greater, because the aforementioned Full HD mode lets you increase the refresh rate up to 240 Hz. There is essentially one feature missing that Samsung has already got us used to, namely Dolby Vision Gaming. Xbox owners will notice this most, as that console can use Dolby Vision in games. There is one more thing worth mentioning specific to this model. Its One Connect module has only one HDMI 2.1 port, so you must plug the console or PC into that port if you want to use 4K at 120 Hz. Fortunately Samsung did not combine this port with eARC. The soundbar can therefore be connected separately (3) and you still have a full HDMI 2.1 available for the console.
