Samsung QN900D Neo QLED 8K vs Philips OLED910

The Samsung QN900D television demonstrates its high capabilities in light production in synthetic tests without any issues – 1400 nits is truly an impressive figure. It also showcased these capabilities in the first scene from the film "Life of Pi," where we see a brilliant burst of the rising sun. However, due to problems with the dimming algorithm, some issues can be noticed here. In the test scenes from "Sicario 2" and the second scene from "Life of Pi," these values are no longer as high and amount to around 500-600 nits. While this may not be the worst result among Mini LED televisions, one could expect more given the price of the television. Nonetheless, the television deserves praise for covering a wide colour gamut of DCP P3 at 96%. Although there are technologies offering higher values, this result is still satisfactory.

The 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 not long ago was completely unattainable in OLEDs. The television also deserves high praise for how it handles full-screen scenes drenched in bright light. Generally, in OLEDs, brightness drops significantly during such scenes, but here it remains at an excellent level – around 1400 nits. These are almost reference values, and combined with the 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 television QN900D offers a Filmmaker mode that has been created with the intention of watching films in the most natural way possible, however, this mode is not without certain flaws. For HD content, the white balance shows a dominance of red and blue colours, causing the image to take on pink hues. In contrast, for 4K HDR content, the situation is the opposite – the decrease in blue and red levels warms up scenes and shifts colours towards yellow tones. This is confirmed by Color Checker tests, which clearly show that colour samples are veering in this direction.

As for brightness and the associated contrast, the gamma is significantly impaired. The biggest issue is a noticeable jump at the beginning of the graph, which indicates that dark details are excessively brightened, resulting in a loss of depth in the darkest areas of the image – this is due to local dimming. For 4K HDR materials, the EOTF curve looks quite good, however, it remains below the reference level, impacting the overall dynamics of the image.

Unfortunately, when it comes to colour reproduction straight out of the box, the Filmmaker mode on the OLED910 performs really poorly. The television overemphasises the blue colour, and at times it looks almost like a shop display mode. This gives the impression that the manufacturer hasn’t quite tuned the device properly. The effect is that the colours look unnatural, and the whole thing resembles a somewhat exaggerated display from a market exhibition. HDR content is presented much better, where, apart from a slight loss of detail in the blacks, there’s not much to complain about. The problem is that in everyday viewing, it’s the SDR materials that matter the most – and on the OLED910, they simply look poor and fall well short of what we would expect from a television of this class.

After calibration, the Filmmaker mode can indeed be called worthy of its name. The white balance for both HD and 4K HDR content has been significantly improved, making colours more natural and consistent. The image has gained in realism, and pink hues in HD content have been effectively eliminated, as has the yellowish glow in 4K HDR content. Thanks to calibration, the television now offers much better colour reproduction, positively affecting the viewing experience.

As for brightness, the situation with gamma is now quite the opposite – at the beginning of the graph, there is a noticeable drop, making the darkest details harder to discern. The EOTF curve for 4K HDR content has remained largely unchanged and is still below the reference level, meaning the television still struggles to maintain proper brightness. This is related to the aggressive dimming algorithm that affects the overall brightness of the image. You can see how the television fights to maintain high brightness or perfect black.

Despite the limitations associated with local dimming, the Samsung QN900D has improved colour reproduction quality, as confirmed by the Color Checker test results – the colour samples are now much closer to the targets, making the image more natural and pleasing to the eye.

Fortunately, it quickly turned out that it was not the panel causing the problems, but rather the way Philips factory-calibrated the OLED910. 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 adjusted the white balance and brightness characteristics, successfully taming the excessive blue and giving the image a natural appearance. 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 colours presented in accordance with the creators' intent. In SDR content, the effect was outstanding, 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 confidently be referred to as a reference in terms of colour quality.

The fluidity of tonal transitions in lower-quality materials is impressive – the Noise Reduction feature effectively smooths tonal transitions while eliminating film grain. Although the removal of grain is not always desirable, the overall final effect looks very aesthetically pleasing, particularly for those who prefer a cleaner image.

When it comes to upscaling, or image scaling, QN900D shows the enormous potential of the new processor with AI technology. Images and materials in lower resolution are upscaled while preserving many details – for example, a photo of a model looks fantastic, free of unnecessary jagged edges, and the branches in the background are not overly jagged.

The previously visible colour banding can largely be mitigated thanks to a feature called "distortion reduction." Like in the OLED820, it is best set to a medium level, as it then produces fairly decent results – smoothing out unwanted tonal transitions while not taking away too much detail from the image. Although at times the effect may be slightly too aggressive, this function can be considered useful for everyday viewing.

As for image scaling, the OLED910 performs really well. The test material featuring a model had a soft look characteristic of Philips – at times almost too soft – but this can be easily corrected with the sharpness slider, allowing you to adjust the image to your own preferences. It's also worth noting that the television has no issues with overscan, which still occurs in some competitor 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.

Samsung QN900D is currently the fastest television in the world – literally. A refresh rate of 240 Hz in 4K resolution is an incredible value that PC gamers will surely appreciate. As for cinema fans, they will not be disappointed either – Samsung offers a 10-step clarity scale in the picture settings, allowing for image adjustments. We can choose whether the television should provide a smoother, theatrical effect at the highest settings, or a more cinematic experience, with visible frames, at the lowest settings.

OLED910 is a television 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 panel used 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 the OLED panel – lightning-fast pixel response time and the absence of motion blur, the image is impeccably sharp and quick, even in dynamic action scenes. The traditional motion smoother from Philips, called “Motion Style,” also deserves praise. We can easily adjust it to our preferences: the “Fluidity” slider is responsible for films and allows you to choose between a more “filmy,” cinematic character and a smooth, theatrical image. Meanwhile, the “Motion Blur Reduction” slider is intended for sports, where it’s worth setting it to the maximum value to ensure that the image is clear and distinct during very fast shots.

Samsung QN900D is a television that offers excellent compatibility with consoles and a range of features that gamers will appreciate. It has 4 HDMI 2.1 ports, although unfortunately without the full bandwidth of 48 Gb/s. Nevertheless, for the average user, this is more than sufficient. Additionally, the television supports Auto Low Latency Mode (ALLM) and Variable Refresh Rate (VRR), which means a smoother image and no screen tearing during dynamic gameplay. The G-Sync and FreeSync technologies also deserve attention, as they ensure optimal cooperation with consoles and computers equipped with the appropriate graphics cards, minimizing stuttering and providing a smooth image.

One of the unique features available only in Samsung televisions is the Xbox Game Pass app, which allows for game streaming without the need for a console. This is a very convenient solution that lets you enjoy your favourite games without the need to purchase additional hardware. Furthermore, the QN900D has a Game Bar – a special panel that enables quick access to game-related settings, making the configuration of game mode fast and intuitive.

Another interesting feature is a function called Auto Motion Plus Game, which is a special motion smoothing mode that can increase the frame rate (operating at a maximum for a 4K@60Hz signal). Importantly, this does not cause a significant increase in input lag, allowing the player to enjoy both greater image smoothness. All these features make the Samsung QN900D an excellent choice for those looking for a gaming television with the highest possible specifications.

The OLED910 is fantastic for gaming. It supports 144 Hz, so if someone has a powerful PC, they can comfortably utilise that potential. On consoles, the most important thing is still 120 Hz, and everything works perfectly here. There's VRR, an automatic gaming mode, and even Dolby Vision in games and HGiG mode, so we really get a full package of gaming features. Philips has also added a Game Bar, which is a quick menu that displays basic information and allows you to enable a few useful things. It may not look as modern as the competition, but it works and fulfils its purpose. The only downside is the number of HDMI 2.1 ports. There are only two, which can be quite disappointing for a TV in this class. If someone connects two consoles and something additional through eARC - like a soundbar (which doesn't make much sense in this model but I'll discuss that in the paragraph about sound) - they'll have to do some adjustments. Other than that, the OLED910 has everything we expect from a gaming television.
