Philips OLED910 vs Philips OLED820

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 dubbed its "META OLED." It is this panel that allows for over 2000 nits of brightness in films, which was previously completely unattainable in OLEDs. The way the television handles full-screen scenes drenched in bright light is also commendable. Usually, in OLEDs, brightness drops significantly, but here it remains at an excellent level - around 1400 nits. These are almost reference values, and combined with the great color gamut 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.

When it comes to HDR quality, the Philips OLED820 uses the same class of WOLED panel that we find in its biggest competitors – LG C5 or Samsung S90F. This means we can count on truly solid performance. This year, mid-range OLED panels are capable of exceeding the threshold of a thousand nits, and the model tested reaches around 1300 nits in some films. This is an outstanding result that allows for an extremely precise depiction of the director's vision, as contemporary productions are mastered in such brightness ranges. Of course, there are situations where even the OLED820 has to compromise. Full-screen scenes flooded with white, like those in the movie The Meg, can drop brightness to 400–500 nits, which clearly weakens the effect. This is a characteristic of OLED technology that has not yet been fully eliminated. Despite this limitation, it is hard not to appreciate the HDR in this model – high luminance and wide coverage of the DCI-P3 color gamut at 99% make the picture simply look great.

Unfortunately, when it comes to color reproduction right out of the box, the Filmmaker mode on the OLED910 performs poorly. The television overly emphasizes the color blue, and at times it almost looks like a store mode. It gives the impression that the manufacturer hasn't quite calibrated the device properly. The result is that colors look unnatural, and the overall effect resembles a somewhat exaggerated display from a market showcase. HDR content looks much better, where aside from a slight loss of detail in blacks, it's hard to find fault with anything. The problem is that in everyday viewing, it is the SDR materials that matter the most – and on the OLED910, they simply look bad and are far from what we would expect from a television of this class.

The color reproduction in the factory settings really surprised us, and positively so. The Philips OLED820, switched to Filmmaker mode, immediately showed that it was quite well tuned in terms of color. The white balance was relatively accurate, though with a slight lack in the blue hue, which sometimes gave the image a slightly yellowish tint. However, this is not a flaw that particularly interferes with everyday viewing. A larger problem arose with the brightness characteristic. The gamma chart clearly deviated from the ideal, with the line being below the expected values, causing the image to be overly brightened, and the colors looked as if they were covered with a light milky filter. This effect was also noticeable in tests using the Colour Checker pattern, where more pronounced errors appeared.

Fortunately, it quickly turned out that it was not the panel that was responsible for the issues, but rather the way Philips had calibrated the OLED910 from the factory. After calibration, the television displayed its full potential, and only then could we see what the new panels produced by LG Display were truly capable of. We primarily corrected the white balance and brightness characteristics, which allowed us to tame the excessive blue and give 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 perfection and colors presented in accordance with the creators' intentions. In SDR content, the effect was remarkable, and in HDR, the improvement was even more noticeable – gradients became cleaner, and colors fuller and more believable. After calibration, the OLED910 transformed from a disappointing television into equipment that can easily be called reference-level in terms of color reproduction.

After calibration, both the Filmmaker mode and the game mode gained quite a lot. A slight adjustment of the white balance and an improvement in brightness characteristics resulted in excellent outcomes for SDR content – the image looked almost perfect, natural and very close to the reference. In the case of HDR materials, the situation was similar; the colors looked stunning and it was hard to find anything to criticize. However, we noticed a certain feature that we had already pointed out when comparing scenes from the movie Billy Lynn. An analysis of the EOTF curve revealed that the television has a slight tendency to dim details in the blacks, which means that the darkest sections are not always displayed exactly as the director intended. Nevertheless, the effect after calibration is remarkable, and the OLED820 stands out as one of the more interesting screens in its class. It just needs a little bit of fine-tuning, and there's really nothing to be afraid of.

The previously visible color artifacts can largely be eliminated thanks to a feature called "distortion reduction." Similar to the OLED820, it's best to set it to a medium level, as it then produces quite decent results – smoothing out unwanted tonal transitions while not taking away too many details from the image. Although there may be times when the effect is a bit too aggressive, it can generally be considered a useful feature for everyday viewing.

As for image scaling, the OLED910 performs really well. The test material with the model had a characteristic soft look typical of Philips – at times even too soft – but the sharpness slider can be adjusted at any moment to tailor the image to personal preferences. It's also worth noting that the TV has no issues with overscan, which still occurs in some competing models. It's a small detail, but it's pleasing because it means that all content, even the oldest, is displayed as it should be.

Fortunately, the earlier effects of the aforementioned posterization can be quite effectively mitigated. The "distortion reduction" feature set to medium handles unwanted color banding, improving the smoothness of tonal transitions. It does happen, however, that it works a bit too aggressively and smooths out some details – such as minor skin imperfections of the actors – but despite this, it can be considered worth using without major compromises. The upscaling in the OLED820 also performs well. The test image with the model is exceptionally soft, sometimes even too much so, although this can be alleviated by slightly increasing the sharpness in the picture menu – it’s a matter of personal preference. The lack of overscan issues with very low-resolution content is also commendable, meaning we don't have to worry that the image will be unnecessarily cropped.

The OLED910 is a television with a refresh rate of 144 Hz. It's a bit disappointing that Philips didn't choose 165 Hz, because we know that the panel used in it is capable of that. On the other hand, such a bonus would mainly benefit PC gamers, as in everyday use, the most important refresh rate is 120 Hz, which is fully sufficient. Combined with the advantages of an OLED panel – lightning-fast pixel response time and no motion blur, the image is impeccably sharp and fast, even in dynamic action scenes. Kudos also goes to Philips' traditional motion smoother called "Motion Style." We can easily adjust it to our preferences: the "Smoothness" slider is for movies and allows you to choose between a more "frame-like," cinematic character and a smooth, theatrical image. Meanwhile, the "Blur Reduction" slider is for sports; it is worth setting it to the maximum value here to ensure that the image is clear and distinct during very fast shots.

Motion fluidity is an area where OLEDs always shine, and the Philips OLED820 confirms this rule. The panel itself offers a refresh rate of 144 Hz, which will mainly benefit PC gamers, but even with standard television sources or consoles, where 120 Hz is used, the motion is fast, sharp, and simultaneously smooth, without traces of ghosting. This is thanks to the outstanding response time between pixels, which ensures the image retains clarity in every dynamic scene. The manufacturer has also added its own smoothing feature called "Motion Style." In the menu, we find two sliders – the first, responsible for fluidity, allows us to adjust the amount of artificially added frames in movies. This way, we can choose a raw, cinematic character with a clearly visible film frame or a more theatrical image with smooth motion. The second slider is for reducing blurring, especially useful in sports broadcasts. Here, we definitely recommend setting it to the maximum value, as the effect is truly excellent.

The OLED910 is excellent for gaming. It supports 144 Hz, so if someone has a powerful PC, they can easily take advantage of that potential. On consoles, 120 Hz is the most important, and everything works perfectly here. There is VRR, an automatic game mode, and even Dolby Vision in games along with an HGiG mode, so we actually get a full package of gaming features. Philips also added a Game Bar, which is a quick menu that shows basic information and allows you to enable a few useful things. It may not look as modern as the competition, but it works and serves its purpose. The only downside is the number of HDMI 2.1 ports. There are only two, which can be somewhat disappointing for a TV in this class. If someone is connecting two consoles and something additional to eARC - like a soundbar (which doesn't make much sense in this model, but we'll discuss that in the sound section), they'll need to figure things out a bit more. Other than that, the OLED910 has everything we expect from a gaming TV.

Philips OLED820 is one of the most complete televisions for gamers. It practically has everything you could expect: two HDMI 2.1 ports with full bandwidth of 48 Gbps (too bad there aren't four), variable refresh rate VRR, automatic game mode ALLM, support for Dolby Vision in games, and a good implementation of the HGiG mode. The television also handles lower resolutions at 120 Hz without any issues, so you can count on great flexibility when choosing different picture modes on the console. Philips also adds Game Bar – a panel that allows you to change picture modes, add a crosshair, or view parameters. Although it looks quite clunky and is less polished than that of the competition, it serves its purpose. In practice, therefore, the OLED820, besides having a full set of four HDMI 2.1 ports, offers almost everything a gamer might need.
