Moving from one video standard to another is a pretty messy process. It requires an entire ecosystem of cameras, players, displays, and software. One of the big-buzz items at this year's Consumer Electronics Show in Las Vegas is one of those conversions: the move from HDTV to 4KTV. A 4K display, as you would expect, has roughly four times the pixels of an HD display, which means much (much) sharper images. Trouble is, we're still so early in the 4K conversion that we're missing a key thing: um, content. At its press conference this morning, Sharp unveiled a clever stopgap—something to tide us all over until 4K is affordable enough for the average Joe.
