The CEA has released the designation of "Ultra HD" or "Ultra High Definition" to refer to 4k displays. According to research, consumers find the name "Ultra HD" to be more helpful than 4K. This name was established to help avoid consumer confusion as 4K TVs start to roll into big box stores. In order to be labeled as Ultra High-Definition or Ultra HD TVs, the display needs at least eight million active pixels, with at least 3,840 horizontally and at least 2,160 vertically. The display must also have the standard HD aspect ratio of 16:9. At least one input on the display needs to support native 4K without relying on upconversion. We don’t think that this move will avoid all of the confusion, but applaud the CEA for establishing a standard.
