Is 1080p (1920x1080) almost as good as it gets? Or is it worth pushing the resolution much higher? I know that's only about 100dpi, but can I actually resolve objects smaller than a quarter of a mm from two feet away?
(Come to think of it - 1080p being 100dpi on a 22" monitor seems an unlikely coincidence - is that why it was chosen?)
