Sony Bravia 9 (XR90) vs Samsung QN900D Neo QLED 8K

The results of brightness measurements on the Sony Bravia 9 are phenomenal. Each scene reaches well over 1500 nits, and when watching films, the television can sometimes shine even brighter. It goes without saying that such brightness allows for unprecedented experiences and engagement with video material at the highest possible quality. Thanks to the high coverage of the DCI-P3 colour palette, the image is full of colours and, combined with such high luminance, it practically breathes. With high peak brightness, viewers can enjoy the full range of colours even in the most challenging scenes, such as those based on dynamic lighting changes. The Bravia 9 offers support for Dolby Vision and HDR10 formats, which further enhances the viewing experience.

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 best factory mode in Sony televisions has consistently remained "IMAX Enhanced" for years. It was this mode that we used throughout the entire testing procedure. Although it is indeed the most similar to the standard compared to other predefined options, it has a number of aspects that can be improved to make viewing even more enjoyable. When we look at the gamma in SDR materials, we notice quite a significant boost that will be associated with image contrast. It is worth noting that the very beginning of the graph has an even greater rise compared to the reference, leading to a blending of details in the blacks, creating a uniform blot. The EOTF curve in HDR content looked quite correct and exhibited only minor deviations from the reference. However, a common feature for both was: a green colour dominance in white balance, issues with greys and overall colour misalignment. The aspect that stood out the most was related to the uneven distribution of hues in white balance. Due to the excess of the aforementioned colour, the image was covered with an unpleasant greenish tint.

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.

The colour reproduction after the calibration process should be regarded as excellent. Regardless of the signal, whether SDR or HDR, we can expect an image that is remarkably close to what the film director saw. Virtually every flaw in the image has been modelled and maximally corrected. This was made possible thanks to the advanced tools used for the calibration process, which Sony has been providing in its televisions for years, including 2- and 20-point grey scale adjustment as well as a very comprehensive CMS.

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.

Let’s take another look at the quality of tonal transitions, but this time we will analyse the quality of image scaling, which will be significantly important when watching lower quality materials. For starters, we will take a look at the function responsible for the quality of tonal transitions. And while by default they are quite average, after activating the option, even at the lowest level, we can confidently say that these are among the best we have seen. You can confidently enable this feature, as it does not cause any negative phenomenon, such as film grain blurring.

Sony has been boasting for several years now that its "XR" processor is unmatched when it comes to image scaling. And we find it quite easy to believe, because in fact the image is extremely sharp, yet very natural.

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 maximum refresh rate of the Sony Bravia 9 is 120 Hz. This is the essential minimum for watching primarily sports or materials with significant motion dynamics while maintaining a sharp and smooth image. For demanding users, the manufacturer has implemented a very comprehensive smoothing system, which has been divided into three segments: Smoothness (Film), Smoothness (Camera), and Clarity. The first two correspond to the degree of blurring and the degree of smoothing, respectively. The third option will be described in more detail below. Moreover, we can adjust all settings to various degrees, each of which will produce an effect, ensuring that we can find our own golden mean. In the picture, we present a setting with slight smoothing, without the soap opera effect.

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.

The Sony Bravia 9 television is equipped with four HDMI ports. However, somewhat inexplicably for a device of this class, only two of them operate in the 2.1 standard. That said, it should not be overlooked that almost all functions perform excellently and do not cause any negative feelings when being activated. Games running either in HDR10 or Dolby Vision have very low input lag, allowing for a very comfortable session with the title. A consolation remains in the form of a good implementation of the HGIG mode, which, after proper adjustment, does not differ significantly from Dolby Vision.

A year ago, Sony added to its televisions what has long been a standard for some manufacturers. This refers, of course, to the GameBar, enabling quick adjustment of settings without the need to exit the game. The implementation of this feature was successful and works very efficiently. We have been provided with conveniences such as: a crosshair grid, black level correction, and the option to reduce the screen to the proportions of gaming monitors.

The Sony Bravia 9 will undoubtedly find its fan base, most likely among PlayStation enthusiasts. Here, we must admit that it will be the most sensible choice, as in practice both the console and the television possess exactly the same capabilities. Looking at the bigger picture, while overlooking the issues with Dolby Vision in games, one cannot detract from the fact that the Bravia 9 is a very good television in the context of gaming.

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.
