Samsung OLED S90F (QD-OLED) vs SONY Bravia 9 II XR95M2

The biggest difference between the 65-inch S90F and the other versions is brightness. The QD-OLED panel can reach up to 1700 nits in laboratory tests, which is over 500 nits more than the version with a WOLED matrix. This translates to a significantly stronger and more immersive HDR effect. In most scenes, the bright parts of the image look stunning, and we must admit that we were positively surprised, as we expected results closer to the WOLED version, but what we got is an effect that impresses even in films. As with every OLED, there are moments when the panel must reduce brightness a bit. This mainly concerns full-screen, very demanding scenes – for instance, in the last test scene from the movie “The Meg,” brightness drops to around 800 nits. However, it's hard to consider this a flaw because it's still an excellent result, unprecedented in OLED TVs in this price range. Everything suggests that the 65-inch S90F could be one of the best choices this year for those looking for a strong OLED at a reasonable price. Another advantage of the QD-OLED matrix in HDR content is its colour gamut coverage. Thanks to quantum dots, the television achieves nearly 100% of the DCI-P3 gamut and almost 90% of the BT.2020 gamut. These are values that place it alongside much more expensive models and make it exceptional in its class.

The real showcase for the new backlight architecture and Sony’s processor is HDR reproduction. At the official launch the Sony engineers said (not officially 😉) that the Bravia 9 II’s brightness should be almost identical to their professional director’s monitor BVM-HX3110, priced at astronomical sums. Our lab tests confirmed they weren’t empty promises. In synthetic measurements on the L20 test pattern the TV easily exceeded 4000 nits of peak brightness. More importantly, these impressive results translate directly to real film scenes. In most of the demanding shots we tested the screen consistently held brightness around 2500 to 3000 nits. Whether the light was small and pinpoint or flooded almost the entire screen, the HDR effect was incredibly intense.

Colours

Colour is another key pillar of RGB Mini LED technology (Sony’s True RGB implementation). For testing this type of panel we’ve permanently added a new research section to check how TVs handle colour in real-world conditions. Traditional synthetic-chart tests are no longer enough to determine real gamut coverage. From now on we also measure colour saturation directly in selected film scenes by overlaying measurement points. So how do the colours perform?

In synthetic tests the Bravia 9 II posts excellent results. For the popular DCI-P3 space used for HDR, colour-gamut coverage was almost 98%, while for the extremely wide and demanding BT.2020 space our measurements showed nearly 90%. However, in real-world, varied scenes those values drop by a few percentage points. This is directly due to the nature of zoned RGB backlighting. When differently coloured elements or bright white points appear next to each other, light from adjacent zones begins to mix slightly, producing a whitish backlight. This, of course, affects colour saturation, slightly reducing it. It shows that despite Sony’s brilliant algorithm controlling the RGB diodes, that number of zones is too small to eliminate the effect completely.

Is this a reason to complain? Of course not. The Bravia 9 II’s final colour coverage is the same as that of a very good QLED TV, and it’s important to remember: the vast majority of films and TV shows distributed in HDR use the DCI-P3 gamut. In that standard Sony easily maintains very high colour saturation, regardless of the scene.

Samsung S90F, like most modern televisions, offers several picture modes, but in keeping with our tradition, we checked it in the most important one, which is Filmmaker. This setting makes the picture look much more natural than in the default, often oversaturated modes. It is neither overly vivid nor artificially dimmed – just closer to what you should actually see. However, this doesn’t mean it’s perfect. The S90F had noticeable shortcomings in white balance, particularly in the blue range, which created a slightly yellowish filter effect on most scenes. One might argue that it looks more “cinematic” because it’s warmer, but let’s not kid ourselves – George Lucas didn’t shoot Star Wars in sepia 😉 (you’ll find a comparison with a scene as always below). In HDR materials, there was also an issue with brightness management. The EOTF curve clearly showed that the television brightens the image more than it should, which led to some effects looking too intense and deviating from the reference. Fortunately, many of these flaws can be eliminated through professional calibration – we will discuss the effects of this procedure later in the test.

Contrary to expectations and high hopes, the Bravia 9 II we tested straight out of the box showed some issues with its factory calibration. Looking at the white balance charts, you can see it isn’t perfect. In SDR content it mainly lacked the red component, so the picture leaned toward cooler, bluish tones. By contrast, white balance in HDR looked much better in that respect. So where do the visible errors in image reproduction come from? They stem from an unexpected tuning of the gamma and the EOTF curve. In both cases the Bravia 9 II straight from the factory showed a clear deviation from reference standards.

In SDR content the gamma was significantly too high, at times running very close to 2.8 instead of the reference 2.4. In practice this meant the image was artificially dark and appeared washed out of colour, with details in dark areas (the shadows) completely lost. The opposite was true in HDR material, where brightness reproduction is handled by the EOTF curve. That curve was pushed too high above the correct value, which resulted in the picture being artificially brightened across most luminance ranges. As with every TV we test, we also subjected this unit to professional calibration. You can see the results and how we managed to correct those factory errors below.

Calibration quickly revealed that the S90F has a significant reserve of capabilities. The image in SDR immediately gained a natural quality – classic films no longer looked like someone was applying a yellowish filter, and the colours regained their proper character. It's a return to the atmosphere of the original, without the impression that someone tried to "age" it forcefully. In HDR content, the difference was even more pronounced. The EOTF curve was managed to nearly reference level, and any deviations are so subtle that most viewers wouldn't even notice them. In practice, the S90F shows an image very close to ideal post-calibration. Compared to the WOLED version, it even performs better – mainly due to a wider coverage of the colour palette, which makes the colours look fuller and more vibrant.

Fortunately, with professional calibration, most of the factory shortcomings of the Bravia 9 II can be effectively eliminated. We managed to precisely correct primarily the white balance and the gamma and EOTF curves. After those adjustments, in everyday use and during movie sessions the TV looks vastly better. The image gained proper dimensionality, the cool tint to the whites disappeared, and shadow details that had previously been lost due to excessively high gamma finally became clearly visible. Although we ultimately assess colour accuracy as very good, as specialists we must point out one fairly serious design flaw in this model. The Bravia 9 II could look even better if it weren't for the complete lack of an advanced colour management system in the TV's menu.

While a basic white balance correction can be carried out here without issue, the settings lack options for adjusting specific colours. We tried to tackle this from every angle, both using the traditional method from the remote and with dedicated calibration software for Bravia TVs. Unfortunately, that function has been entirely locked. We suspect this may stem from the specifics of the new RGB architecture, which imposes these limitations. It's a real shame, because without it you can't fine-tune colour reproduction to perfection. The inaccurate red, for example, still stands out. Let's hope Sony will fix this shortcoming over time via an update.

S90F performs really well here, although there are some points that are common across most Samsung TVs. The noise reduction feature can effectively smooth out unwanted colour transitions in lower-quality materials like television or YouTube, making them look simply better. However, it should be noted that it works quite aggressively and can also soften elements that we wouldn’t want to alter, such as facial details. Therefore, if we want to use it, it’s best to use it in the "medium" setting and be aware of the compromise it brings. The upscaling itself is of a high standard – low-quality materials are pulled towards an image resembling 4K. The only caveat is that the S90F can still have issues with so-called overscan, meaning slight trimming of the edges in very low-quality materials such as 576p and lower.

Digital processing and upscaling have long been Sony's forte, and after testing the Bravia 9 II we can confidently say that nothing has changed in this area. Sony remain at the top of the market. Their proprietary XR image processor, which in this model works together with the main MediaTek Pentonic 1000 chip, deserves the highest praise. That combination delivers excellent results. Upscaling lower-resolution content is extremely effective and precise.

However, what earns the most praise in the XR processor's performance is its tonal transition smoothing function. The system can reduce posterisation in heavily compressed material to practically zero. Crucially, the algorithm does this in a very intelligent way. It removes only the irritating digital 'steps' in gradients (banding), but does not blur fine texture detail or create an artificial, 'plastic' look lacking film grain. The image remains sharp, natural and cinematic.

S90F is an OLED with a refresh rate of 144 Hz, but in practice, what matters most is how it performs at 120 Hz, as this frequency is the most important when watching sports. The QD-OLED panel is no different in this regard from WOLED panels – the pixel response is nearly instantaneous, so motion is rendered with surgical precision. The effect is easy to predict. The image is practically free of motion blur, making gaming on consoles, matches, or other sports broadcasts a tremendous pleasure on the S90F.

Fans of movies and series have not been forgotten either. Like every Samsung television with a refresh rate of 120 Hz and above, the S90F is equipped with a proprietary motion smoother called “Picture Clarity.” Here, we find two sliders – blur reduction and judder reduction – which allow you to improve the smoothness of content recorded at 24 frames and tailor the effect to your own preferences.

In the specifications for the Sony Bravia 9 II you won't find dizzyingly high screen refresh rates above 120 Hz, which some more demanding PC gamers might see as a drawback. However, in everyday use — whether during film sessions, playing console games or watching sport — it's really hard to criticise the motion smoothness. The VA panel used here does exhibit some slight, natural smearing typical of this panel type, but the excellent Motionflow smoothing algorithms come to the rescue. The system menu includes sliders for blur reduction and smoothing that let you precisely tune the motion characteristics to your own preferences.

The S90F is a television that genuinely brings a lot of joy when gaming. To start with, we get four proper HDMI 2.1 ports, which means you can connect all consoles and PCs without having to figure out which device takes priority. This is a convenient and practical solution, which is not at all a given with other manufacturers. Additionally, there are key features such as: automatic game mode (ALLM), which automatically switches the screen to low latency settings, and VRR frame synchronization that operates over a wide range from 48 to 144 Hz. This ensures the picture remains smooth, whether we're playing fast-paced online shooters or more relaxed narrative titles. The Game Bar also deserves attention – a panel that allows quick access to several handy extras. For example, you can turn on an extra crosshair in the middle of the screen, enlarge the minimap, or, in the case of PC, change the aspect ratio. Finally, there's also Samsung's unique Game Motion Plus mode. Its task is to smooth out older or poorly optimized titles, and it actually works quite well. With this mode, even less polished games can look better and provide more enjoyment than on other televisions that theoretically offer the same technical parameters.

Aside from the fairly serious design oversight of limiting the platform to just two full HDMI 2.1 ports, the Bravia 9 II offers almost all the key gaming features available on the market. Sony has already accustomed us to such a rich feature set in its previous designs. The list of supported technologies here is extensive. It includes automatic low-latency mode (ALLM), variable refresh rate (VRR), as well as a fully compliant implementation of the HGIG standard and Dolby Vision tailored specifically for gamers.
