Our Verdict
Sony X90J
Sony X91J
The Sony X90J and the Sony X91J sit alongside each other in Sony's 2021 TV lineup, but they have a few different features. The X90J is available from 50 to 75 inches, and it uses the Cognitive Processor XR processor, while the X91J is meant to be a larger variant with a different processor, the 4k HDR Processor X1. Both TVs are fairly similar overall, but the newer processor on the X90J has some advantages. Local dimming is much better on the X90J with less blooming, and it gets brighter, especially in HDR. The X90J delivers a sharper image when upscaling, but that's also because the 85 inch X91J has a lower pixel density, resulting in a less sharp image. Overall, while they're similar overall, the X90J is slightly better due to its processor.
