Philips PUS8079 vs Xiaomi S Pro 2026

The maximum brightness in content with a wide tonal range at 202 nits is extremely low and practically prevents watching movies and series on streaming platforms in the highest quality. It's worth mentioning that in this case, using the HDR format equipped with dynamic metadata won't help either. Why won't it help? Because the only such format implemented in the television is HDR10+, which is extremely unpopular, and films recorded in this format are scarce. It’s also worth noting that PUS8079 uses WLED backlighting, which unfortunately is not the best solution, resulting in coverage of only 80% of the wide DCI-P3 colour gamut. The effect of this reality is significantly less intense colours in HDR content.

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 terms of colour reproduction and fidelity to the director's vision was "Film". While it was the best of the predefined modes, it still had significant discrepancies between what the filmmaker wanted to convey and what the tested television displayed. In both SDR and HDR materials (though to a lesser extent in the latter), the white balance, which is the most fundamental element responsible for image purity, turned out to be somewhat of a repeat of the vibrant mode, with a blue tint reminiscent of what you see in retail displays. Moving directly to the SDR materials and what affects contrast, namely gamma, we see it being severely reduced. This leads to cutting off already minimal contrast resources and brightening the entire image. In the EOTF curve, responsible for the increase in brightness pace in HDR materials, we instead see a strong drop below the reference line, which, given the limited light output of the television, significantly impacted the perception of those contents, which were even more dimmed. We won’t separate the quality assessments of the colours themselves since, in both cases, they achieved astronomical deltaE values, being simply completely different from what they should be.

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.

Luckily, Philips implements advanced image correction tools in all of its TVs. SDR content has benefited the most here, and the huge deltaE errors have been significantly corrected, with both white balance and gamma being substantially reworked. While we can't say it's reference-quality image, it's definitely better, and you can watch a movie or series without causing a headache, especially for your eyes. Naturally, HDR materials, due to the very low luminance of the TV, could not be corrected to the same high degree as those with a standard colour palette, but we managed to roughly straighten out the EOTF curve and the white balance. Unfortunately, that was all we could squeeze out of our unit, although it's worth noting that each unit is different and has entirely different errors, whether minor or major.

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.

We will return once again to the issue of tonal transitions, but in the context of overall image quality improvement. As we can observe in the photo on the left, the gradation enhancement feature works brilliantly. Furthermore, it offers several settings, and each of them, even the lowest, provides a beneficial effect, and, what’s more, does not soften the film grain effect. We will repeat once again that this feature is the biggest advantage of the tested television.

Secondly, we will look at image scaling. Here, the tested television performed worse. We can notice, above all, the strongly jagged fine details and the characteristic white glow around figures. We must not forget about the significant artificial sharpening of the image.

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.

This paragraph, unlike the others, will be extremely short. The reason for this situation is the lack of implementation of even the most basic motion smoothing function, which was to be expected given the price of the device. We also note that we are dealing with a VA panel, whose sharpness will not be the best under the sun. This type of panel is mainly associated with high contrast, which goes hand in hand with a relatively slow response time, as we can clearly read from the panel analysis results. As you can see, from the images captured in quick motion, the picture is blurred, typical for this type of panel. Although it may not be the ideal option, it can conditionally be used for watching sports, although one must keep in mind the less than optimal sharpness in motion. It's worth mentioning that movies will exhibit stuttering, as the television does not have any, not even the simplest, motion smoother.

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.

Philips PUS8079 offers only the most basic support for gaming in the form of ALLM, VRR, and Game Bar. The most important information is that thanks to the implementation of the feature responsible for dynamic refresh rate adjustment, the image is actually quite smooth for this price range and does not 'tear' the image.

A slightly greater nod towards gamers is the introduction of the Game Bar, allowing for settings adjustments 'on the fly'. This means we won’t have to exit the game to make any changes to the image. Importantly, it hasn’t been stripped of options known from higher models. We can find features such as shadow enhancement for better visibility in shadows and a colour filter for players with visual impairments.

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.
