Are you using a DVI->VGA adapter. I found that my nvidia card didnt like 
detecting a monitor connected that way if I was using the edid flag 
options for the nvidia driver. If instead of allowing the card to detect 
the spec's of the monitor I simply put in the horizontal and vertical 
refresh specs it worked perfectly. I also found that it doesnt like 
having any other connector plugged in when the dvi connector is in use 
(ie no svideo or vga).

Just thought I might pass along some hints, unfortunately every nvidia 
card seems to be different!
