4K x 2K video with to-die-for resolution now has an official name. The Consumer Electronics Association (CEA) has decreed that it will be called Ultra High-Definition or Ultra HD. The latter rolls trippingly off the tongue, doesn’t it? Try it a few times. Ultra HD sets must have at least 8 million pixels, 3,840 horizontal x 2,160 vertical, with an aspect ratio of 16:9 or wider, and at least one digital input must provide that minimum resolution without upconverting.

The decision came from a working group based on consumer research showing that the Ultra HD moniker rated highest in helping consumers understand the technology and describe the viewing experience. But there’s at least one dissenter: A day after CEA unveiled the new name, Sony announced that it would continue to designate its highest-resolution sets as 4K or 4K UHD.
