Sony 55" 4K Smart TV KD55X81KU 2022

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 quality, full of life-like colour and contrast.

TRILUMINOS PRO™

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.

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 HD are upscaled close to 4K levels of detail by 4K X-Reality™ PRO using a unique 4K database.

Motionflow™ XR

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.

Auto Low Latency Mode

With Auto Low Latency Mode in HDMI 2.1, BRAVIA recognises when a console is connected and powered on, and automatically switches to low latency mode. You'll enjoy smoother, more responsive gameplay – vital for fast-moving, high-intensity games.

Auto HDR Tone Mapping

With Auto HDR Tone Mapping the HDR settings will be optimised instantly during your PS5™ console’s initial setup. Your PS5™ automatically recognises individual BRAVIA TV models and selects the best HDR setting for your TV accordingly. So even in high contrast scenes, you’ll see the crucial details and colours in the brightest and darkest parts of the screen.5

X-Balanced Speaker

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.

Auto Genre Picture Mode

BRAVIA automatically switches into Game mode to minimise input lag and make the action more responsive. When watching movies on PlayStation5® consoles, it switches back to Standard Mode to focus on picture processing for more expressive scenes.6

Bluetooth connectivity

Connect Bluetooth® compatible devices to your TV for easy wire-free entertainment. Pair your Bluetooth headphones or earphones with BRAVIA and enjoy TV shows and music in your favourite place - without any disturbances or interruptions.7

Ambient Optimization

Sit back and enjoy an enthralling viewing experience. Our unique ambient optimisation technology with light sensor automatically adjusts picture and sound to your environment.

Light Sensor

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.

Sound optimisation for your room

Sound experience can change depending on your room environment. Curtains, for example, absorb sound while objects in front of the TV can disturb the passage of sound, compromising the quality of what you hear. This TV detects objects and reproduces sound that’s enhanced and optimised to your room.

Works with BRAVIA CAM

Connect your BRAVIA TV with BRAVIA CAM, sold separately, for an even more immersive viewing experience. BRAVIA CAM recognises where you are in the room and how far you are from the TV, then adjusts sound and picture settings so they're just right. You can also enjoy an array of fun new TV experiences with BRAVIA CAM including gesture controls, video chat and many more.
