Hi all. My dad's looking for a new PC monitor, and I figured I may as well ask here to see if any of yous know any good ones.

What he wants is:
20"+
Good contrast ratio (1000:1+)
Vertical: 1024.

It doesn't need speakers at all as we already have plenty to work with. The main reason he wants a new monitor is to get a reasonable size to compare two documents when the windows are tiled vertically.

Any help would be appreciated. Ask any questions if you need to.
