Philips PUS8079 vs Philips OLED910

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.

OLED910 is simply an absurdly bright television for an OLED. All thanks to the new panel from LG Display, the Tandem RGB OLED, which Philips has branded as "META OLED". It is this panel that allows for over 2000 nits of brightness in films, which not long ago was completely unachievable in OLEDs. The way the television handles full-screen scenes flooded with bright light also deserves high praise. Usually, in OLEDs, brightness drops significantly, but here it remains at a great level – around 1400 nits. These values are almost reference-level, and combined with excellent colour reproduction at 99% DCI P3 and 82% BT.2020, it gives us an HDR effect that can confidently be called one of the best in the world.

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.

Unfortunately, when it comes to colour reproduction straight out of the box, the Filmmaker mode on the OLED910 really falls short. The television overemphasises the blue colour and at times it looks almost like a shop mode. It gives the impression that the manufacturer hasn't quite calibrated the device properly. The result is that colours appear unnatural, and the overall look resembles a slightly exaggerated display from a store showcase. HDR content looks much better, where apart from a slight loss of detail in blacks, there’s hardly anything to complain about. The problem is that in everyday viewing, it’s actually SDR materials that matter the most – and on the OLED910, they just look poor and significantly deviate from what we would expect from a television of this class.

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.

Fortunately, it quickly turned out that it wasn't the panel causing the problems, but the way Philips factory-tuned the OLED910. After calibration, the television showcased its full potential, and only then could we see what the new panels from LG Display were truly capable of. We primarily corrected the white balance and brightness characteristics, successfully taming the excessive blue and giving the image a natural look. The final effect can be described as excellent. Errors on the Color Checker palette rarely exceeded a value of 3, which in practice means an image close to ideal and colours presented in line with the creators' intent. In SDR content, the effect was stunning, and in HDR, the improvement was even more noticeable – gradients became cleaner, and colours fuller and more accurate. After calibration, the OLED910 transformed from a disappointing television into equipment that can be confidently referred to as reference-grade in terms of colour accuracy.

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.

The previously visible colour connections can be largely mitigated thanks to a feature called "distortion reduction." Similar to the OLED820, it’s best to set it to medium level, as it then provides quite decent results – smoothing unwanted tonal transitions while not taking away too many details from the image. Although at times the effect may be a bit too aggressive, in everyday viewing, this function can be considered useful.

When it comes to image scaling, the OLED910 performs really well. The test material with the model showcased a characteristic soft look typical of Philips – at times almost too soft – but at any moment this can be adjusted with the sharpness slider to tailor the image to your own preferences. It’s also a plus that the television has no issues with overscan, which still occurs in some competitors' models. It’s a minor detail, but it’s pleasing as it means that all content, even the oldest, is displayed as it should be.

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.

OLED910 is a TV with a refresh rate of 144 Hz. It’s a bit of a shame that Philips didn’t opt for 165 Hz, as we know that the matrix used in it is capable of that. On the other hand, such a bonus will mainly benefit PC gamers, as for everyday use, the most important thing is the 120 Hz refresh rate, which is fully sufficient. Combined with the advantages of the OLED matrix – lightning-fast pixel response times and the absence of motion blur, the picture is impeccably sharp and fast, even in dynamic action scenes. The traditional motion smoother from Philips called “Motion Style” also deserves praise. We can easily adjust it to our own preferences: the “Smoothness” slider is for movies and allows you to choose between a more “framey,” cinematic character and a smooth, theatrical image. Meanwhile, the “Motion Blur Reduction” slider is intended for sports; here, it’s worth setting it to the maximum value so that the image is clear and sharp during very fast shots.

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.

The OLED910 is fantastic for gaming. It supports 144 Hz, so if someone has a powerful PC, they'll easily make the most of that potential. For consoles, the most important thing is still 120 Hz, and everything works smoothly here. It has VRR, an automatic game mode, and even Dolby Vision in games along with HGiG mode, so we pretty much get a full package of gaming features. Philips also added a Game Bar, which is like a quick menu that shows basic information and allows you to enable a few handy features. It might not look as modern as the competition, but it works and does its job. The only downside is the number of HDMI 2.1 ports. There are only two, which can be quite disappointing in this class of television. If someone connects two consoles and something extra to the eARC - like a soundbar (which doesn't really make sense in this model, but more on that in the sound section), they'll have to do a bit more figuring around. Other than that, though, the OLED910 has everything we expect from a gaming TV.
