Sony Bravia 9 (XR90) vs Philips OLED820

The brightness measurement results on the Sony Bravia 9 are phenomenal. Each scene achieves well over 1500 nits, and while watching movies, the TV 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. With a high coverage of the DCI-P3 colour gamut, the image is full of colours and, combined with such high luminance, it practically breathes. Thanks to the high peak brightness, viewers can enjoy the full spectrum of colours even in the most difficult scenes, such as those based on dynamic lighting changes. The Bravia 9 supports Dolby Vision and HDR10 formats, which further enhances the viewing experience.

When it comes to HDR quality, the Philips OLED820 uses the same class of WOLED panel found in its biggest rivals – the LG C5 and the Samsung S90F. This means we can expect really solid results. This year, mid-range OLED panels can exceed the threshold of a thousand nits, and the tested model reaches around 1300 nits in some films. This is an outstanding result, allowing the director's vision to be conveyed with incredible precision, as this is the brightness range in which modern productions are mastered. Of course, there are situations where even the OLED820 has to compromise. Full-screen scenes flooded with white, like those in the film The Meg, can drop brightness to 400–500 nits, which clearly diminishes the effect. This is a characteristic of OLED technology that has not yet been fully eliminated. Despite this limitation, it's hard not to appreciate the HDR in this model – high luminance and a wide coverage of the DCI-P3 colour palette at 99% make the image look simply fantastic.

The best factory mode on Sony televisions has remained "IMAX Enhanced" for years. This is what we used throughout the entire testing procedure. Despite being the closest to the reference 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 is related to over-contrasting the image. It is worth noting that the very beginning of the graph has an even greater spike compared to the reference, which leads to the merging of details in the blacks, creating a uniform blob. The EOTF curve in HDR content looked quite accurate and only showed slight deviations from the reference. However, a common characteristic for both was: a greenish tint in the white balance, issues with greys, and general colour misalignment. The most noticeable issue was related to the uneven distribution of colours in the white balance. Due to the excess of the aforementioned colour, the image was covered with an unpleasant greenish tint.

The colour reproduction in the factory settings really surprised us, and in a positive way. The Philips OLED820, switched to Filmmaker mode, immediately showed that it was quite well tuned in terms of colour. The white balance was relatively accurate, although there was a slight deficiency in the blue hue, which sometimes gave the image a slightly yellowish tint. However, this is not a drawback that particularly interferes with everyday viewing. A bigger problem arose with the brightness characteristics. The gamma chart clearly deviated from the ideal, as the line was below the expected values, causing the image to be excessively brightened, and the colours 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.

The colour reproduction after the calibration process should be regarded as excellent. Regardless of the signal, whether it's SDR or HDR, we can expect an image incredibly close to what the film director saw. Practically every image flaw has been modelled and maximally improved. This was made possible by the advanced tools used for the calibration process, which Sony has provided in its televisions for years, including 2- and 20-point grey scale adjustment and a very elaborate CMS.

After calibration, both the Filmmaker mode and the gaming mode improved quite a bit. A slight adjustment of the white balance and enhancement of the brightness characteristics yielded excellent results with SDR content – the image looked nearly perfect, natural, and very close to the reference. For HDR material, the situation was similar; the colours looked fantastic, and it was hard to find fault with anything. However, we did notice a certain characteristic, which we had already pointed out when comparing scenes from the film Billy Lynn. The analysis of the EOTF curve showed that the TV has a slight tendency to dim details in the blacks, meaning that the darkest parts are not always displayed exactly as the director intended. Nevertheless, the effect after calibration is superb, and the OLED820 is emerging as one of the more interesting screens in its class. A little bit of fine-tuning is all that’s needed, and there’s really nothing to worry about.

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 crucial when watching lower quality materials. We'll start with the function responsible for the quality of tonal transitions. While they are quite average by default, after activating the option, even at the smallest degree, we can confidently say that these are some of the better ones we've seen. You can confidently enable this function, as it does not cause any negative phenomena, such as grain blur.

Sony has been boasting for several years that its "XR" processor is unmatched when it comes to image scaling. And it's not hard for us to believe that, because the image is indeed incredibly sharp, yet very natural.

Fortunately, the earlier effects of the mentioned posterisation can be quite effectively mitigated. The "distortion reduction" feature set to medium handles unwanted colour banding well, improving the smoothness of tonal transitions. It does sometimes work a bit too aggressively and smooths out some details – such as the minor imperfections of the actors’ skin – but despite that, 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 perhaps too much, although this can be remedied with a slight increase in sharpness in the picture menu – that's a matter of individual preference. The absence of overscan issues with very low-resolution content is also commendable, allowing us to not worry about the image being unnecessarily cropped.

The maximum refresh rate of the Sony Bravia 9 is 120 Hz. This is the essential minimum for watching primarily sports or content that has a lot of movement dynamics while maintaining a sharp and smooth image. For demanding users, the manufacturer has implemented a very advanced smoothing system, which is divided into three segments: Smoothness (Film), Smoothness (Camera), and Clarity. The first two correspond to: blur degree and smoothing degree, respectively. The third option will be described in more detail below. Additionally, we can adjust all settings to various levels, each of which will have an effect, ensuring that we can find our very own sweet spot. In the photo, we present a setting with slight smoothing, without the soap opera effect.

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 TV sources or consoles, where it operates at 120 Hz, motion is fast, sharp, and simultaneously smooth, without any signs of smearing. This is thanks to the remarkable response time between pixels, which ensures the image maintains clarity in every dynamic scene. The manufacturer has also added their own smoothness enhancer called "Motion Style." In the menu, we find two sliders – the first, responsible for smoothness, allows for the adjustment of the number of artificially added frames in films. This way, we can choose a raw, cinematic character with clearly visible film frames or a more theatrical image with smooth motion. The second slider is for motion blur reduction, particularly useful in sports broadcasts. Here, we definitely recommend setting it to the maximum value, as the effect is truly excellent.

The Sony Bravia 9 television is equipped with four HDMI ports. However, somewhat incomprehensibly for this class of device, only two of them operate in the 2.1 standard. Nevertheless, it shouldn't be taken away that almost all features work excellently and do not cause any negative feelings upon being activated. Games operating in either HDR10 or Dolby Vision have a very short input lag, allowing for a very comfortable session with the title. A consolation remains in the good implementation of the HGIG mode, which after proper tuning does not deviate significantly from Dolby Vision.

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

Sony Bravia 9 will certainly find its group of fans, most likely among PlayStation enthusiasts. Here, we must admit that this will be the most sensible choice, as in practice both the console and the television have exactly the same capabilities. However, looking more broadly, aside from issues with Dolby Vision in games, one cannot deny that the Bravia 9 is a very good television in the context of gaming.

The Philips OLED820 is one of the most comprehensive TVs for gamers. Onboard, we find practically everything one could expect: two HDMI 2.1 ports with full bandwidth of 48 Gbps (shame there aren't four), Variable Refresh Rate (VRR), Auto Low Latency Mode (ALLM), support for Dolby Vision in games, and a good implementation of the HGiG mode. The TV also handles lower resolutions at 120 Hz without issue, so you can count on great flexibility when choosing different picture modes on your console. Philips also adds a Game Bar – a panel that allows you to change picture modes, add a crosshair, or preview parameters. Although it looks a bit clunky and is less refined than its competitors, it gets the job done. In practice, therefore, the OLED820, in addition to a full set of four HDMI 2.1 connections, offers almost everything a gamer could need.
