Samsung S85F (WOLED) vs Xiaomi S Pro 2026

For most of the time, let's say in 90% of film scenes, viewers will hardly see any difference between the S85F versions. When small but very bright light points appear on screen – a lantern in a dark alley, a gunshot, the sun breaking through the clouds – this WOLED panel (just like the smaller S85F) performs exceptionally well. Our measurements showed a peak brightness of around 750 nits. We can confidently state: this is a great result that guarantees fantastic HDR effects. The problem arises in a very specific, uncomfortable situation for any OLED. We're talking about the moment when the entire screen has to shine at full brightness clearly. Examples include a white background screen, a skiing scene, or our test sequences (5) from the film The Meg. And here, unfortunately, the results diverge quite significantly against the WOLED panel variant. Our measurement equipment was able to measure a maximum of around 250 to 300 nits of brightness under such conditions. To be clear: the same model on a QD-OLED panel in the same test is almost twice as bright. The second issue: colours. And here we also have to be honest – QD-OLED has a structural advantage. Why? It’s simple. QD-OLED creates colours from three components (red, green, and blue) and doesn’t need an additional white subpixel. The WOLED panel we’re testing here uses that white subpixel, mainly to boost overall brightness. The effect is that QD-OLED is able to display a slightly wider colour palette, and the colours are a bit "cleaner." But let’s be clear: it’s not that the colours on this WOLED panel are bad! Quite the opposite, they are really very good. Coverage of the DCI-P3 film colour gamut at 97% and 71% for the wider BT.2020 palette is still high-end. We just have to honestly admit that those few percentage points of coverage advantage lie with QD-OLED technology and may be noticeable in very specific moments.

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.

When it comes to factory colour reproduction, our test unit in SDR mode suffered from a slight deficit in red and yellow. This resulted in a subtle yellowish tint visible in shades of white. However, this is not the biggest issue with the S85F. Similar to the QD-OLED panel variant, the main problem with this model is the way it presents HDR content. When we look at the EOTF curve graph, it’s easy to see that the TV has quite significant issues with strong image over-brightening. This results in the final image becoming very unnatural in many scenes.

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 conducting calibration in Filmmaker mode, we managed to eliminate most unwanted effects. In SDR content, the TV performs exceptionally well, and its colour reproduction errors do not exceed a value of 2, which is an outstanding result. The HDR content looks a bit worse, though still very good. Although we managed to eliminate a significant unnaturalness of the image caused by an overly high EOTF curve, the most discerning observers may notice that it is not perfectly aligned. It runs slightly below the reference curve, which would suggest that the S85F has minor issues in displaying all details in the image. We must immediately point out that it is highly unlikely for the average viewer to notice any deficiencies in the picture. We assess the final result after calibration as exemplary.

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 processing of tonal transitions (gradients) in the S85F is at a high level. The television effectively handles posterization (the "stepping" effect of colours), even with heavily compressed content, for example, from streaming services. However, using this feature requires a certain compromise. We noticed that the noise reduction algorithm is quite aggressive – even at the lowest setting, it can eliminate the natural film grain, which for many viewers is part of the film's aesthetics. The "Standard" setting seems to be a golden mean, without causing a noticeable loss of important details, so we can recommend it. However, we advise against using the "High" level, which, in addition to noise, also removes desired details such as texture or the structure of objects on the screen.

The upscaling process of lower resolution content works very well in the S85F. The image is sharp and clear. The only minor imperfection we managed to observe is occasional slight aliasing on the edges. The television still displays characteristics typical of this manufacturer, namely active "overscan" (a slight image enlargement). This should be kept in mind, especially when watching older content, as it may result in minimal clipping of the original frame.

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.

S85F is a model with impressive speed. The use of a 120 Hz OLED panel ensures that dynamic scenes, both in games and during sports broadcasts, perform as expected: smoothly, sharply, and without loss of clarity. A key role here is played by the lightning-fast pixel response time, which is a natural advantage of OLED technology. Transitions between frames are instantaneous, and the image remains clear even during the fastest camera movements. Moving objects, like a ball on the field or a car in a chase scene, are clear and free from the characteristic smearing of LCD panels (so-called "trail").

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.

85F has practically everything on board to become the dream screen for gaming. It features four full-fledged HDMI 2.1 ports with a bandwidth of 48 Gb/s, support for VRR (Variable Refresh Rate) and ALLM (Auto Low Latency Mode). Additionally, there is a super-detailed Game Bar that clearly shows all the key parameters. However, the real gem is the Game Motion Plus feature. This motion smoother dedicated to games makes the animation more pleasant to the eye while only slightly increasing input lag. This is a rare and well-functioning combination that deserves big applause for Samsung.

Now comes the moment where we need to vent a little. The lack of Dolby Vision in Samsung TVs has become standard, so there's no use hoping (unless something changes in the future). Unfortunately, it's much harder to explain the disappearance of support for HGiG after one of the software updates. HGiG (HDR Gaming Interest Group) is a key mode that allows for precise representation of brightness in HDR games, as intended by the creators. Without it, HDR calibration on consoles becomes less accurate, which may result in images that are too dark in the shadows or overly bright in the light areas. Perhaps Samsung will fix this in the next update – we have high hopes for that. Because if HGiG returns, the S85F will become nearly the perfect TV for gamers.

[UPDATE] We have updated our tests of Samsung TVs from the 2025 lineup due to the release of software version 1131, which restored the crucial HGiG feature for gamers.

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.
