I posted my xorg.conf about an hour or so ago in another thread. You 
need to set your DPI to 100x100, and set UseEdidDpi False, to start.
You may also need to check out how your card treats the VGA output 
versus DVI. It may view that as 2 separate outputs which need to be 
dealt with separately...which may mean enabling the DVI.. or not.
The man pages for nvidia and xorg.conf will help.
