Our X1™ Ultimate twice as fast as the X1™ Extreme precisely analyses and processes data to enrich 4K 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. 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.

It does this by ‘sampling’ the speaker frequency with higher precision. This information is fed back to cancel out any peaks or dips in the speaker’s natural response – resulting in pure natural audio with smooth even reproduction of all frequencies.
