4K Will Now Be Called Ultra HD

Getting their brand names in order, the Consumer Electronics Association (CEA) announced the so-called 4K high definition resolution format will now be referred to as Ultra HD, which is probably more descriptive to many consumers - if it's ultra something, it must be better, right? In this case, the Ultra HD standard is concisely stated thus:
To qualify as Ultra HD, a display needs to have a resolution of at least 3,840 pixels horizontally and at least 2,160 pixels vertically, the CEA said. Additionally, the product will require at least one 4K-capable digital input and display 4K content natively without upconverting.
