ultrahdThe next generation of ‘4K’ high definition display technology will now be known as ‘Ultra High-Definition’ or ‘Ultra HD,’, according to the Consumer Electronics Association (CEA).
Ultra high definition TVs have more than eight million pixels of resolution, four times the resolution of today’s high-definition televisions .
CEA’s Board voted to endorse the consensus opinion of CEA’s ‘4K’ Working Group recommending the term ‘Ultra High-Definition’. The name and related minimum performance characteristics are designed to help consumers and retailers understand the attributes of this next generation of television and display technology.
The Working Group, now known as the CEA Ultra HD Working Group, was formed earlier this year to bring a wide array of stakeholders together to discuss how best to define and educate consumers about this new technology.

The group also defined the core characteristics of Ultra High-Definition TVs, monitors and projectors for the home. Minimum performance attributes include display resolution of at least eight million active pixels, with at least 3,840 horizontally and at least 2,160 vertically. Displays will have an aspect ratio with width to height of at least 16 X 9. To use the Ultra HD label, display products will require at least one digital input capable of carrying and presenting native 4K format video from this input at full 3,840 X 2,160 resolution without relying solely on up-converting.
Digital Cinema 4K standard is unaffected by the name change as this is a different technical standard with 4096 x 2160 resolution at film frame rates.
