One clear trend at this year's NAB show is the proliferation of digital video cameras with a native resolution of at least 4K (roughly 4000x2000 pixels). Among the entries in this field is a prototype from JVC, which doesn't even have a model designation, much less a price or shipping date.

I was particularly impressed that JVC was displaying the camera's output on a 55-inch 4K flat panel, probably a Sharp, though the rep I spoke with couldn't say for sure. Unfortunately, the photo above, taken directly off the screen, does not do the razor-sharp image justice. Even more amazing was an IBM 4K monitor nearby measuring only 20 inches or so diagonally—I could get close enough so my eyeball was almost touching the screen, and I could barely see the pixels. These flat panels give me hope that 4K will migrate to consumer displays.
