I've recently purchase a new gaming computer and would now like to look at a new monitor. Currently im using an acer 1366x768 18.5" monitor and a gtx 570 GPU. I've been pondering over the 20" monitors and the 21.5' monitors. My real question is, do games look better on resolutions like 1920x1080p on a 21.5" then they do on a 1600x900" 20" monitor considering they have equal contrast, response time and all that extra jazz? I've always thought they would look the same since the extra pixles are there because of the larger screen, but my friend is trying to convince me otherwise.
