Question : Problem: resize laptop screen

stand-alone monitors have resize buttons on the monitor itself, to stretch height & width.

how to do this on a laptop?   inspiron del 9300.    It has 1.5" margins on all 4 sides in XP.

There is underlying problem (incomplete list of resolutions available to select) I don't have the time to fix -- like trying dell's website for new drivers, etc..  I'd rather just fix the symptop.
