Sony 55 Inch 4K Ultra HD Smart TV KD-55X90K 

• Take vision and sound to the next level with Cognitive Processor XR™. Our revolutionary processor on Sony BRAVIA XR™ TVs reproduces content the way humans see and hear for an incredibly lifelike experience. It understands how the human eye focuses, cross analysing images to give real life depth, extraordinary contrast and beautifully vivid colours. 
• Our Full Array LED, powered by Cognitive Processor XR™, controls the backlight in zones to reproduce realistic contrast in bright and dark areas simultaneously. The intelligent processor sees the world as you do, enhancing pictures with real life colour and depth.
• Powered by Cognitive Processor XR™, our Full Array LED panel with unique new LED structure and XR Triluminos Pro enables X90K to access over a billion colours and reproduce each one with the subtle differences seen in the real world. It can detect colour from saturation, hue and brightness to deliver natural shades in every detail, especially in greens and reds.
• Paired with Sony audio equipment, our latest BRAVIA XR TVs go even further, bringing you an unmatched audio-visual experience with outstanding XR picture and sound quality.
