With XR Contrast Booster bright areas are brighter and dark areas darker, so no more details overwhelmed by shadow or lost in blown-out highlights. We test input lag using an HDFury Diva HDMI matrix to measure the amount of time between when a TV receives a signal and the screen updates. In Cinema mode, the A90J shows an input lag of 151.9 milliseconds, which is far too high to be comfortable. However, switching to the Game picture mode makes that lag drop to just 9.9ms. That’s less than half of the 20ms threshold we use to consider a TV to be among the best for gaming. Standout Sound With more apps than any other smart platform, there’s something for everyone on Google TV. Run by Android, explore even more applications on the Google store. If you prefer to watch shows on live providers, then browse through the available options on the integrated digital TV service. Are you a fan of Google Assistant and voice control? Just speak to this 4K TV through the remote, to change channels, get tailored suggestions, and more. From dark scenes like the Game of Thrones finale, to bright football matches, this stunning XR55A90JU has amazing contrast to display true to life picture quality. At the heart of theXR55A90JU is the XR Processor, keeping the image optimized and stunning to watch. Not only is the Sony A90J one of the best picture performers we’ve tested, it also sounds superb by TV standards. Because the sound genuinely comes from the screen, audio and video are tied together far more effectively than from most TVs. In Blade Runner 2049, as K (Ryan Gosling) takes his baseline test, there’s a rare directness to the delivery. At the same time, the A90J’s virtualised surround sound adds space to the presentation so that the reverberations of the room and the disembodied voice of the interrogating officer stretch beyond the confines of the set itself.
The Sony X90J has a good color gamut, but it's just short of the required 67% Rec. 2020 coverage to be considered a wide color gamut. It's lower than the Sony X900H, although the difference is pretty small and isn't noticeable. It's very difficult to tell that it doesn't have a wide gamut just by looking at an image. We measured this multiple times with different settings and picture modes, and we also compared it side-by-side with the Sony X80J, with both TVs receiving the same 4k, 4:2:2, 10-bit signal through an HDMI splitter. We took the readings with a colorimeter and spectroradiometer set up three feet from the TV, and we also took a spectrum reading, which you can see here. The results were the same. We measured a wide color gamut by lowering the stimulus received, but HDR is meant to be watched with a bright image. The most variation is with the 10% windows, which are significantly brighter than the rest. If that bothers you, you can disable the Peak Luminance setting. With it off, we measured the real scene brightness at 442 cd/m². Scenes are more consistent, with most windows measuring between 468 cd/m² and 479 cd/m², but there's some frame dimming in the 2% windows, with both peak and sustained at around 349 cd/m². We suggest leaving Peak Brightness on if you want the brightest screen possible with an accurate image. If youcomeacross a different type of panel or your SonyX90J doesn't correspond to our review, let us know, and we'llupdate the review. Note that some tests, like the gray uniformity, may vary between individual units. Please note: Failure to produce the card and relevant ID means we are unable to release goods on collection. Retested 1080p VRR range to see if there were still the same issues with latest firmware, and changed the PS5 VRR test to 'Yes' because it supports it.Offering 4K HDR TV technology this stunning XR55A90JUis ready for the future, and has unmatched picture quality. Cognitive Processor XR is designed to replicate the way our brains think to optimisethe picture and sound accordingly. With XR Contrast, Colour and Motion theXR55A90JU is truely next level in its ability to produce the best picture possible. Updated to Test Bench 1.7 with an updated HDR Brightness test that better reflects real world usage. We've also split the console compatibility boxes into separate PS5 Compatibility and Xbox Series X|S Compatibility tests. You can see our full changelog here. Please note, this Smart TV features third party Apps. These Apps may be modified or withdrawn at any time. There may also be a delay in launching some of the featured Apps. Catch-up TV Apps may vary by region. The function and availability of apps is not covered by the manufacturer’s or Richer Sounds’ guarantee. The Automatic Brightness Limiter (ABL) is less aggressive, and the most notable changes are in the 10% windows, which are much brighter. If that's distracting for you, we measured the brightness with the Peak Luminance setting disabled. The brightness drops considerably, with real scenes measuring at 498 cd/m². All windows are between 493 cd/m² and 565 cd/m², except the 2% peak and sustained windows, which are around 320 cd/m². While disabling Peak Luminance can help reduce the effect of the ABL, it doesn't deliver an impactful HDR experience.
In 2021, there’s a new settings menu called HDR Tone Mapping. Our measurements use the 'Gradation Preferred' setting, but it may be helpful to note that while the 'Gradation Preferred' setting results in a more accurate EOTF, the 'Brightness Preferred' setting lets you get a brighter image without having to make too many other adjustments. If you want to see the difference these settings make, you can see the 'Brightness Preferred' EOTF here and the EOTF with HDR Tone Mapping disabled here. We retested the variable refresh rate feature with the latest firmware (PKG6.5660.0668NAA), confirming that VRR now works across the full refresh rate range. Prices valid in stores (all including VAT) until close of business on 28th November 2023. (Some of these web prices are cheaper than in-store, so please mention that you've seen these offers online.) As the Rogue One crew approaches Scarif, the scene is rendered with epic scale. The gateway to the planet and the ships surrounding it are crisp and three-dimensional, the sunlight reflecting off the planet’s surface is piercingly bright and each cloud is easily discerned, despite the great distance. With XR Contrast Booster bright areas are brighter and dark areas darker, so no more details overwhelmed by shadow or lost in blown-out highlights.

It’s also available in the following sizes: At the core of the TV is Sony’s new Cognitive Processor XR, which combines the AI abilities of its X1 predecessor with a system that Sony calls cognitive intelligence. While AI analyses picture and sound signals and uses data based on machine learning, cognitive intelligence aims to add a more human perspective to identify and enhance AV performance and deliver an experience in line with how humans see and hear the world.
