Improving upon the Picture Processor X1, the Sony BRAVIA XR MASTER Series Z9J 8K TV uses the Cognitive Processor XR. This means you get cognitive intelligence on top of already great artificial intelligence algorithms. The Sony Z9J televisions understand things in a more human way, making them more effective overall. Available in 75- and 85-inch sizes, the Sony BRAVIA XR MASTER Series Z9J also comes with updated Bravia XR Sound for a new dimension of television audio. It uses 3D Surround Upscaling with new actuators and frame tweeters to create a virtual 5.1.2-channel experience. Taking both vision and sound to the next level, this television knows how you see and hear to truly immerse you. You’ll love the amazing 8K pictures thanks to the full-array LED panel. Finally, use Google Assistant for hands-free navigation.
