My old 22" Diamondtron 2060u can do 1920x1440@75Hz and 2048x1536@60Hz.
4:3 does seem too narrow now though. A large widescreen is more productive and pleasant to use.
I agree. I went from a 22" Diamondtron to a 22" LCD. At first I didn't like it being wider, but I've gotten used to it and anything else seems narrow.
Due to the arrangement of the eyes, people have a field of view that is wider than it is high, so widescreen makes sense. my issue with 16:9 isn't in the aspect ratio - I don't mind it. My issue is that they get it by removing vertical height, not by adding horizontal width.
