Samsung makes great monitors. Ive got two 17in for dual monitor, but i think he is looking for a bigger monitor then 19". Dell makes good lcd monitors too. Both 20" and 22" lcd will display 1680x1050 resolution, so your not getting more desktop space with the 22". The difference is the 22" will display it bigger. For example, the same text on a web page on the 22" will be bigger compared to the 20". I suggest you go to your local computer store and find a 20" and a 22" widescreen and figure out which one is more comfortable to your eye sight.
