Whatever you're watching, you'll see it upscaled close to 4K 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. XR Smoothing creates smooth, natural 4K pictures as you watch, without the “banding” that can occur on other TVs. Scenes are reproduced with thousands of tones, shades and gradations, making them look incredibly real. Watching TV from the sides is now as satisfying as from the centre. Our self-illuminating OLED panel keeps colours consistent and true, wherever you're watching. With a Variable Refresh Rate in HDMI 2.1, BRAVIA avoids stuttering delays and screen tearing. This TV dynamically adjusts the display refresh rate to match the variable frame rates of the gaming device for smoother gameplay. Sound comes directly from the screen with Acoustic Surface Audio. Two actuators vibrate, uniquely turning the entire screen into a speaker to create powerful acoustics that move with the picture so you hear realistic sounds with clear and natural dialogue.
