Whatever you're watching, you'll see it upscaled close to 4K[2] quality thanks to our unique Cognitive Processor XR. You'll also enjoy striking contrast on our OLED screen that's expertly controlled by our unique technology to deliver real life depth and pure blacks in every scene.

Powered by our Cognitive Processor XR, XR Triluminos Pro enables A90K to access over a billion colours and reproduce each one with the subtle differences seen in the real world. Together with our wide colour gamut panel and human-centric processor, it can detect colour from saturation, hue and brightness to deliver natural shades in every detail.
