The vote, which took place in conjunction with the CEA Industry Forum in San Francisco, was unanimous. In addition, CEA’s “4K” Working Group is now known as the CEA Ultra HD Working Group .
Ultra HD was also defined as at least 3,840 horizontal and at least 2,160 vertical pixels, with an aspect ratio of at least 16 X 9.
