What is Ultra HD?
Simply put, Ultra HD is a clearer picture. Ultra HD uses 4,000 pixels to show you a sharper, brighter, more beautiful picture. 4 times the resolution of Full HD.
This picture technology is now being built into most new TV's and you might see it referenced as 4K or UHD for short. It just depends on the brand that's using it.
Getting Ultra HD
Currently you can get Ultra HD on YouView from BT. To get it, you'll need a compatible 4K TV and 4K YouView box. Find out more from the BT Website.
