Step-up LED picture performance for gamers, sports and streaming fans.
The elegant JX850 Series LED TV has an HDR Bright Panel Plus screen, ideal for any room. Our HCX AI Processor automatically adjusts the picture to suit the needs of fast-moving sport, video games, or the latest high-end drama series.

Brilliant contrast, to heighten the drama

4K LED Smart TVs with HDR Bright Panel Plus screens are ideal for rooms with lots of natural light. Producing crisp colourful images and spectacular contrast - even on the brightest of days. Why wait until the evening to start streaming that series?

Spectacular sporting picture performance

HCX AI Processor - The new processor inside this model delivers accurate colour, contrast, and pin-sharp clarity – well suited to fast-moving action. Using AI, the TV knows when you’re watching sport, and adjusts the picture for you.

Impressive sound, that brings the stadium to you

Dolby Atmos® - A great picture is one thing, but it’s so much more involving when you add great sound. Our sound processing, with added immersive Dolby Atmos® technology, can make it feel like you’re sitting in the best seat in the stadium.

The intelligent way to a great picture experience

Auto AI - Using AI, our premium TVs analyse the incoming signal and instantly adjust the picture characteristics. Auto AI knows the settings for sport, filmic scenes and more - so makes them for you. Just sit back and enjoy the performance.

Optimal brightness and colour - in all conditions

Multi HDR Format - By supporting all HDR (High Dynamic Range) formats our premium TVs assure best possible performance - regardless of picture source. Brightness and colour are optimised scene-by-scene; whether the source is Dolby Vision, HLG, HDR10 or the new HDR10+ Adaptive format.
