Ultra High Definition TVs have four times as many picture elements, or pixels, as a 1080p full HD set. That's the highest resolution of any TV screen yet, 4K, enabling UHD sets to display super-detailed pictures. They're not a new type of TV, though: The first models on the market are all LCD sets with LED backlighting. You can appreciate the detail most on large screens.

Here are our first impressions of some of the latest UHD sets, for which we’ll have full reviews soon.
