I use a 19" flat screen @1600 x 1200, with 4 tabels there is no overlap. The tables take up about 99% of the screen though. I have a small sliver where I can see a single line of PT stats, to be sure that it is updating.

I am getting another video card to hook up my old 15" monitor. Maybe PT will go over there, or maybe table #5 and #6 if two can fit. We'll see.
