There are various panel technologies. Each has its own specific features - viewing angles, color reproduction, response time, brightness/contrast, production cost, etc. The image quality depends directly on the type of the display panel used.

The A90J’s glistening array of picture triumphs make it an excellent gaming display, too. The combination of high contrast, rich colours, good detailing and, by OLED standards, impressive brightness are all perfectly suited to today’s HDR gaming worlds, and the screen feels suitably responsive in its Game mode. The ultra-crisp and smooth majesty of 4K 120Hz gaming is also impeccably delivered. 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. Enjoy beautiful pictures from any angle with X-Wide Angle.Information about the number of pixels on the horizontal and vertical side of the screen. A higher resolution allows the display of a more detailed and of higher quality image. We uploaded the brightness measurements and uniformity photos after running the TV for two months in our Accelerated Longevity Test. The Sony A90J has good HDR brightness, good enough to make bright highlights pop. However, there isn't much consistency across scenes with different luminance levels due to the TV's Automatic Brightness Limiter (ABL). It performs similarly to the LG G1 OLED, but it's not as bright as the LG G2 OLED. Warming up the TV doesn't significantly impact the HDR brightness. Converted to Test Bench 1.10. With this update we've revamped our Gradient testing, added a new test for Low Quality Content Smoothing, and expanded our Audio Passthrough testing.

The actuators serve a much more immersive purpose than simply providing crisp sound. The sounds they generate seem to come directly from the screen, rather than simply the general area of the TV. The result is audio that better matches exactly what you’re watching, and a capable center channel that can be integrated into a surround sound system.Some aspects of the A90J’s functionality aren’t quite as complete as its new processing system seems to be, though. For starters, while the set is capable of handling the Dolby Vision, HDR10 and HLG formats of HDR, there’s no support for the HDR10+ system. Like Dolby Vision, this format adds extra scene by scene picture data that compatible TVs can use to render HDR more accurately (and, usually, more dynamically). If you want to see just how extreme the 65A90J’s colours can go, give the Vivid preset a go. You likely won’t want to keep using this for long as its intensity actually becomes pretty tiring, but it certainly helps explain why the TV is so comfortable handling even the most vibrant and bright content in the other more natural modes. The Sony 65A90J’s combination of a new high-brightness panel and sophisticated new processing engine yields pictures that can consistently only be described as breathtaking. Or beautiful. Or maybe breathtakingly beautiful.
