Philips OLED809/819 vs Xiaomi S Pro 2026

Philips OLED 809 delivers a more than satisfactory HDR effect. The television is capable of generating luminance exceeding 900 nits in almost every scene, and sometimes even over 1000. This result allows for a full experience of materials with a wide tonal range. The only moment when Philips OLED 809 cannot generate higher brightness is in a scene from the film "The Meg," which features a large amount of bright white across much of the screen. However, it cannot be said that this is a weak result, as it represents a significant improvement over its predecessor. Overall, such values for OLED panels produced by LG Display, which do not have MLA technology, are very, very good. Combined with high coverage of the DCI-P3 colour gamut, they allow for an HDR experience in a remarkable dimension. Philips OLED 809 test indicated that this television supports popular HDR formats such as Dolby Vision and HDR10+.

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 best factory mode in which we conducted all our tests was "Filmmaker", which is now quite standard in televisions from this manufacturer. However, let's take a look at its characteristics before we start the calibration process. The first aspect we will examine is white balance, as despite being inconspicuous, it determines whether the image will be free from any tints. The graph clearly shows that in both SDR and HDR content, two colours dominated: red and green, which caused a strong yellow tint that was pervasive throughout the image. This is perfectly visible on the "ColourChecker" palette, where all colours shifted towards their warmer counterparts. The second thing we will scrutinise are, in our opinion, the two most important graphs in the context of image quality assessment: gamma and the EOTF curve. Both are intended to maintain appropriate brightness and contrast. The first describes the level of brightness in SDR materials, while the second depicts the rate of luminance increase. Analysing the first one, we can see that it has been remarkably lowered compared to the reference value indicated by the orange line. This situation resulted primarily in a sharp increase in brightness and a significant decrease in contrast, reminiscent of what one would expect from OLED televisions. The EOTF curve showed greater "caution" and only slightly brightened the entire image to 50% of the maximum brightness.

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.

Philips, like most leading manufacturers, has been providing advanced tools for the calibration process for years. Here, we find 2- and 20-point grey scale adjustments as well as an advanced CMS (Color Management System). As you can see, this has brought extremely beneficial results and fundamentally changed the perceived image. Practically every one of the elements mentioned above has undergone a transformation and has been returned to its natural state. This is particularly evident on the "ColourChecker" palette, where the measured samples are harmoniously in their places. It must be said that the white balance has turned out exceptionally well, allowing us to enjoy a clean image free from any tint in both SDR and HDR materials. The biggest issue with OLED809, which is gamma, has been properly modelled and only occasionally shows minor errors that won't affect the overall picture. The EOTF curve, on the other hand, has been stripped of that slight brightening and now presents itself almost referentially.

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.

Philips OLED 809 didn't perform too well in the test for the smoothness of tonal transitions. Moving on to the part of the test where we assess the behaviour of the TV's algorithms, we will again check the function responsible for removing posterisation. In fact, such a function exists in the menu and has several options available. As you can see in the photo on the left, although its presence has been confirmed by us, it is not useful. Only at the highest setting does it effectively remove disruptions, but it blurs the entire image in the process. Therefore, it is completely unusable.

Time and again, you and we find ourselves watching materials of lower quality. In this case, the quality of the image upscaling algorithms can have a salvaging effect. We must admit that those implemented in OLED 809 work quite efficiently and improve the image quality without visible artefacts. You can only notice slight edge blurring, but it is unlikely to be noticeable during normal viewing.

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.

The maximum refresh rate we can set on the tested television is 144 Hz. This value can be achieved by connecting it to a really powerful PC. In the case of consoles or television, everything remains the same. For those who require high movement fluidity or dislike the characteristic judder of films recorded at 24 fps, the manufacturer has prepared a fairly advanced motion smoothing system. In the dedicated tab, we will find the “Smoothness” slider responsible for eliminating judder and “Blur Reduction”, which helps increase the sharpness of dynamic elements. The function works very well and granularly, meaning each of the settings has a real impact on the perception of motion. We also mention that it works at a refresh rate of 120 Hz, as it operates on the multiples of film or television materials. Thanks to such an extensive set, every user will find their happy medium. In the photo, we present our choice, which is slight smoothing without the soap opera effect.

Motion is influenced not only by the settings on the television but also by the response time of the panel itself. OLED televisions feature the best response time on the market, which in the case of 809 is about 0.1 ms. There are no IPS/ADS or even VA panels that significantly come close to the results of organic panels.

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.

The Philips OLED 809 supports all the technologies included in the HDMI 2.1 standard, and during our tests, each one activated without any problems. Therefore, we must state that this television is perfect for all gamers, both those using a console and a computer. It's worth mentioning that the manufacturer has implemented the HGIG mode, which is a great alternative to Dolby Vision, which unfortunately on the OLED809 is unplayable due to the very high input lag.

A nod to gamers is also the inclusion of a dedicated GameBar, which allows monitoring of current gameplay parameters and quick adjustments of settings. There is also a function to activate a crosshair, which will be very useful when shooting from a sniper rifle, but from the so-called hip. Additionally, we can also find a shadow enhancement function for better visibility in shadows and a colour filter for gamers with visual impairments.

In summary, the OLED 809 is a very good and versatile device for gamers. Anyone who purchases this television for gaming does not need to worry about anything, as it is simply designed for gaming. Especially since features such as VRR, ALLM, G-Sync, FreeSync, and HDR Dolby Vision gameplay will allow for an even deeper immersion in their favourite title. Lastly, we should note that the only downside of the television in game mode is the artificial sharpening of the image, regardless of the settings, and it cannot be 'softened.'

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.
