4K displays are available
There are a couple of monitors available that have 4K resolution. There are many different 4K specifications currently, but these three are all 3840x2160. First is the affordable, but maybe a bit large, Seiki 39" SE39UY04. The $699 Seiki is a television first, so connecting a computer takes a little bit of hacking, but from reading the reviews, connecting it to a computer is achievable. Going up in price (way up) and down in size (which may not be a bad thing) are the comparably priced and sized Asus PQ321Q and the Igzo PNK321. Both are in the $3500 range and are 31.5" and 32" respectively. If you are looking for a 4K monitor these are the choices you have today.
