The display format formerly known as 4K will now be called "Ultra High Definition", the Consumer Electronics Association (CEA) announced in California today.

The CEA said that it chose Ultra HD to denote that it has a higher resolution than the existing 1920x1080 pixels of full high-definition.

To qualify as Ultra HD a display needs to have a resolution of at least 3840 pixels horizontally and at least 2160 pixels vertically, the CEA said. Additionally, the product will require at least one 4K-capable digital input and be able display 4K content natively, without upconverting.

"This new terminology and the recommended attributes will help consumers navigate the marketplace to find the TV that best meets their needs", said president and CEO of CEA Gary Shapiro.

There are only a handful of products that are denoted as 4K in the market presently — including a Sony projector, in addition to the LG and Sony TVs. However, at the moment, there aren't any 4K consumer sources beyond a PC output and there is only one 4K feature film. Ultra HD technology is expected to take a prominent place at next year's CES, which will be held 8-11 January 2013 in Las Vegas, Nevada.
