With its UHD screen resolution of 3840 x 2160 pixels, the Sony KD55XD8599 is ready for the 4K revolution. Four times more detailed than Full HD, the gain in resolution is clearly visible and, even close up, the detail and realism are awesome. Thanks to Sony's X-Reality PRO 4K technology, standard FHD images can be upscaled to near UHD quality, giving the sharpest detail possible from your Blu-rays and other FHD sources.

HDR - High Dynamic Range
Taking 4K UHD one stage further, this Sony 55 inch TV is now compatible with HDR (High Dynamic Range). This extends the range of colours for enhanced realism. It also delivers brighter whites and darker blacks, helping to give this TV stunning levels of contrast.

Triluminos display and Motionflow XR1000Hz
As well as 4K, this Sony TV also boasts a Triluminos display; developed to produce truer, deeper and more natural shades of colour, with skin shades appearing far more natural. It's also fitted with Motionflow XR 1000Hz, which works especially well with fast moving action, such as sports events, removing the blur you can see with standard TVs. From a Hollywood blockbuster to a Formula One race, XR1000 makes a significant difference.

Android TV
Offering the slick interaction of the best smartphones, Android TV is one of the smartest content managers and providers to date. Boasting features such as Google Cast, Google Play and Voice Search, this Sony is part TV and part giant smartphone.

Voice Search and Content Bar for effortless searching
Even with such a massive range of content, finding what you want is always easy. Voice Search means you simply say what you're looking for and let Android TV find it for you. The unobtrusive content bar quickly lets you find the movie, TV show or video you're after. Call up the Content bar and you can keep watching, while you scan through live TV, on demand, downloaded TV shows and more.
