Sony Bravia 8 (XR80) vs Samsung OLED S90F (QD-OLED)

Sony Bravia 8 performs reasonably well in terms of HDR brightness. A maximum brightness level of 880 nits is satisfactory and allows for well-rendered lighting effects in most scenes. In the tested segments of the films Life of Pi and Sicario 2, the TV presents itself quite well, offering vibrant and detailed images that fully capture the atmosphere of these productions.

However, a greater challenge arises in a scene from the film The Meg, where the screen is entirely very bright. In such situations, the limitations of OLED technology become apparent, as the TV loses brightness, dropping to around 450 nits. Such a drop is less satisfying, especially when the entire scene requires intense lighting. Despite these limitations, Sony Bravia 8 remains a competitive model, offering excellent coverage of the DCI-P3 colour gamut and 74% coverage of the BT.2020 standard. This results in rich colours and precise details, significantly enhancing the quality of HDR content viewing and making for a pleasurable experience.

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 best factory mode available on the Sony Bravia 8 television is IMAX Enhanced, which provides the most cinematic experience, although it is not set up perfectly. The TV tries to replicate cinema settings as faithfully as possible, however, certain shortcomings are noticeable. Starting with white balance, both for SDR materials and 4K, there is a clear dominance of blue. This makes the picture appear too cold, taking away its naturalness. Tests using Colour Checker show that colours shift towards cooler shades, which may lead to less accurate colour reproduction and makes the image less realistic.

As for brightness and contrast characteristics, gamma shows a significant drop at the end of the graph. This means that dark details may be too dim, while bright elements are too bright, causing them to lose subtlety and become less visible. As can be seen in the sky - in the comparison photo. Meanwhile, the EOTF curve is significantly above the reference value, causing the bright elements of the image to be too intense. As a result, users may perceive the image as unnatural, and bright areas may lose detail, negatively impacting the overall viewing quality.

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.

The calibration process of the Sony Bravia 8 television has brought significant improvements in image quality. The white balance has been distinctly enhanced, both for SDR content and 4K HDR, with minimal errors in the middle section of the graph. Gamma proved to be one of the biggest beneficiaries of the calibration – it has been completely stripped of previous drops, which significantly affected brightness stability and better detail reproduction in dark parts of the image. The EOTF curve has also been levelled out, making bright elements of the image appear more natural, and the overall tonal dynamics are now more balanced.

However, the most attention should be paid to colour reproduction, where despite the calibration, there are still some issues. Sony has omitted the use of a CMS system in this model, which allows for very precise control over colours. Consequently, the Colour Checker test for 4K materials still shows significant errors in colour samples. Despite these difficulties, we recommend carrying out the calibration, as the effects are noticeable and significantly enhance image quality, especially in terms of brightness and contrast.

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.

The fluidity of tonal transitions in low-quality materials on the ChooseTV 8 is lacking. Unfortunately, the gentle gradation feature (which was available in previous models) is missing, which is a significant downside. The digital noise reduction function can improve tonal transitions quite well, but it also tends to remove some details, such as clouds in scenes from the film The Martian, which may not appeal to everyone. When it comes to digital processing, the Sony XR80 TV performs quite well. The model in the test scenes is displayed without noticeable errors, and the branches in the background are not overly jagged. This shows that ChooseTV 8 is capable of processing complex image details at low resolution well.

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.

Sony Bravia 8 offers a maximum refresh rate of 120 Hz, which lays the groundwork for smooth viewing of dynamic content such as sports and games. As a result, movements are sharp and fluid. For more demanding users, the Sony XR80 television is equipped with an advanced motion smoothing system, which is divided into three segments: Smoothness (Film), Smoothness (Camera), and Clarity. The first two are responsible for adjusting the level of blur and smoothing of the image. The third option, concerning clarity, will be described in more detail below. Each of the parameters can be tailored to personal preferences, allowing users to find the optimal setting suited to their individual needs.

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.

Sony Bravia 8 has significantly improved its compatibility with consoles compared to earlier models. The TV supports variable refresh rate (VRR), which eliminates screen tearing, and is compatible with graphics cards, ensuring smooth visuals. The auto low latency mode (ALLM) reduces input lag, which is crucial in fast-paced games. Dolby Vision with low latency additionally provides impressive HDR effects that look fantastic during gameplay.

The Sony XR80 TV also features a Game Bar, which allows quick access to settings and monitoring parameters while gaming. An interesting option is the ability to enable a virtual crosshair on the screen, which can provide a slight advantage in shooter games.

A downside is the lack of support for 1440p@120hz resolution, which could make gaming easier for users with less powerful graphics cards. Additionally, the Sony XR80 only has two HDMI 2.1 ports, one of which is typically used to connect an audio system via eARC, limiting the number of available ports for connecting next-gen consoles.

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.
