My main comp has a triple monitor setup using 3 23" lg screens all at 1920 X 1080.
My laptop has a 17" inch screen at 1680 x 1050 I believe.
My other comp has two 17" monitors at 1400 x 900.
My other comp has a 19" monitor at 1280 x 1024 or something like that.
I also use a 32" lcd and 50" plasma with my main comp - not so much with the plasma due to potential burn in. I generally use the plasma for showing design comps to clients etc.
