A 4K HDTV, also known as an Ultra HDTV or a UDTV, is a television with approximately 4,000 pixels of horizontal resolution. Or, to be more specific, not quite 4,000 pixels of horizontal resolution. A UDTV actually has 3840 pixels horizontally and 2160 vertically, giving it four times the resolution of standard 1080p.
And yes, there's an extremely confusing terminology change here. For many years, we've been describing television resolution by the exact vertical resolution--480, 720, 1080. Now we're supposed to move to an approximate horizontal resolution--with the familiar 1080p (1920 horizontal pixels) being the equivalent to 2K.
