4K HDR TV with OLED screen, Picture Processor X1™ Ultimate and Acoustic Surface Audio

• OLED delivers unprecedented black, contrast and colour
• Picture Processor X1™ Ultimate for unparalleled realism
• Upscale any content to 4K with 4K X-Reality™ PRO
• Sound in harmony with picture for an immersive experience

Reproduces a wider, more precise range of colours

By widening the colour spectrum, TRILUMINOS powered by our X1 processors reproduces more colours than a conventional television. It analyses and processes data in every image to make colours even more natural and precise so pictures are closer than ever to real life.

Supreme resolution, whatever you’re watching

Any kind of content can be upconverted to lifelike 4K resolution with Sony’s unique features. Our X1™ Ultimate, twice as fast as the X1™ Extreme, precisely analyses and processes data to enrich 4K[FN|4K: 3,840 x 2,160 pixels.] pictures with real world detail and texture. Even images filmed in 2K and Full HD are upscaled close to 4K by 4K X-Reality™ PRO using a unique 4K database. Resolution of each subject is then optimised by Object-based Super Resolution to reproduce virtually real world textures.

Boosting colour and contrast for extra depth and realism

See real-world colours, discover the detail in deep shadow and bright highlights. With Pixel Contrast Booster, colour and contrast are enhanced in bright areas so you can enjoy scenes full of lifelike shades and hues, more depth, fine texture and the pure black contrast that only OLED can deliver. 

Beautiful colours from any angle

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.

Super Bit Mapping HDR

There are thousands of tones, shades and gradations of light in a sunset. Super Bit Mapping HDR reveals them. It creates smooth, natural 4K TV picture quality as you watch, without the “banding” that can occur on other TVs.

Making fast-moving scenes bright and clear

With pictures created by millions of individually controlled pixels, everything is sharp and clear on OLED. And with our X-Motion Clarity™ technology, even fast action stays smooth and clear. Moving images are precisely controlled to minimise blur so that pictures remain true with less loss in brightness during high speed scenes.

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.

Sound from the screen, incredibly immersive

Sound on conventional TVs with a speaker located below the screen is often out of sync with the picture. With our Acoustic Surface Audio, the screen is the speaker. An innovative actuator vibrates discreetly to create sound so what you hear comes from the place in the scene where the action is happening – dialogue from characters, engine noise from a car – rather than from speakers at the sides.

Dual database processing

One database is used to clean the picture, reducing on-screen noise. The other is used to upscale the resolution, improving clarity. These two powerful image improvement databases work together, dynamically improving pixels in real time. Each database has tens of thousands of references, amassed from our experience creating content for TV and movies over the years.

Enjoy multidimensional sound with S-Force Front Surround

Hear sound as you would from a separate multi surround speaker. By upconverting inputs, S-Force Front Surround virtually reproduces a multi surround speaker system within your TV so you can enjoy all the thrills of more immersive sound.

Power your soundtracks

With a subwoofer integrated into the rear of the TV, you’ll hear more dynamic, bass-heavy sound – ideal for action movies and music.

Clearly hear voices

With Voice Zoom, you can hear human speech clearly without having to turn up the volume – ideal for news bulletins and documentaries.

Supreme pictures and sound, whatever the environment

Sit back and enjoy the best possible viewing experience. Sony's unique ambient optimisation technology automatically adjusts picture and sound to your environment.

Flexible Metal Blade Stand, sound bar ready

Cable clutter minimised
