HDR 10+

The next advancement in HDR technology, HDR 10+ makes sure every scene is precisely optimised for colour, contrast, and the finest details.


Ultra HD certified

Don't settle for a TV without the Ultra HD certified picture quality logo, which guarantees the pure colours, sharp contrast and brightness you would expect from the latest 4K resolution standards.
