Montior Question: I want to fit 4 tables

[BIGRED]

I'm trying to fit 4 Party tables with no overlap in my 17-in monitor. The max resolution (I'm not sure if this is the right term) I can set is 1280 x 1024. I can work with this, but I still have some overlap on the edges of the table. How can I increase the screen "real-estate so I can fit all 4 tables with no overlaps? Am I limited to 1280 x 1024 because of my screen or because of my computer?
