Well, we're about to see more, a whole lot more - in fact, four times (4X) more - than what we can see now on the best HD screens. Today's screens tickle our retinas with two million pixels. Tomorrow's 4k screens will blast 8.3 million pixels. Pixels so sharp and so clear, you'll think you could walk into the display. The name "4k" has already taken hold in our supersophisticated vocabulary; and we like things short and easy to say. However, last October, the Consumer Electronics Association (CEA) unanimously agreed on the term "ultra high definition" because they like bigger names. They'll let you shorten it to "ultra HD."Sony, however, said thanks but no thanks: We'll call ours "4k UHD." You and I will call them "4k." The term "4k" is a slight exaggeration. The resolution is actually 3840 x 2160 (8.3 megapixels). But the "4"in 4K is the key because a 4k display shows four times as many pixels as an HD display, so you qo from 2 to 8.3 megapixels (Mpix).
