Laptop screen is 17" widescreen 1920 x 1200, all games look great on it.
2nd monitor is a 20" widescreen by acer, bought it from buy.com about a week ago, 1680 x 1059, also a great monitor.
I also have a 32" widescreen lcd hdtv, but I've never felt the need to hook my computer up to it.
P.S. Ignore the date, camera is screwed up.
