Sony 50″ 4K Ultra HDR Smart TV | KD50X81JU
4K HDR processor X1™
Our powerful processor uses advanced algorithms to cut noise and boost detail. With an even clearer 4K signal, everything you watch is closer to 4K resolution, full of life-like colour and contrast.
Our TVs with a wide colour gamut and unique TRILUMINOS PRO™ algorithm can detect colour from saturation, hue and brightness to reproduce natural shades in every detail. You’ll enjoy colours that are closer to those seen in the real world.
Object-based HDR Remaster
With Object-based HDR Remaster, the colour in individual objects on screen is analysed and the contrast adjusted, unlike most TVs where contrast is only adjusted along one black-to-white contrast curve. Because objects are remastered individually, this TV can reproduce greater depth, textures and more realistic pictures.
4K X-Reality™ PRO
See glorious 4K pictures, rich with real world detail and texture, exclusively powered by our 4K HDR processor X1™. Images filmed in 2K and even Full HD are upscaled close to 4K resolution by 4K X-Reality™ PRO using a unique 4K database.
Enjoy smooth and sharp details even in fast-moving sequences with Motionflow™ XR. This innovative technology creates and inserts extra frames between the original ones. It compares key visual factors on successive frames, then calculates the split second of missing action in the sequences. Some models also include black-frame insertion for a blur-free and truly cinematic look.
Designed to complement the sound quality and slimness of the TV with its unique new shape, our X-Balanced Speaker drives movies and music with clear sound.

2-way multi-position stand
A versatile 2-way stand gives you the choice of a standard setting that focuses you on the picture or a narrow setting for smaller shelves.
On conventional TVs, brightness stays the same regardless of light in a room, resulting in pictures that are too dark or bright. This TV includes a light sensor that optimises picture brightness to room conditions, boosting brightness in light rooms and reducing it in dark ones so you get the perfect view.
Dolby Vision® and Dolby Atmos®
Enjoy cinematic thrills at home. Dolby Vision® brings scenes vividly to life for authentic viewing, while Dolby Atmos® fills the room with immersive surround sound.
