Should be a setting in your BIOS somewhere.  Look for Shared Memory or 
Video Memory.  Bump it to at least 512K.

Mind you, I'm taking a wild guess here; I have no idea if nvidia and 
your chipset use shared memory.

Shared memory is when the video card uses a chunk  of your on-board ram 
for video.  It's slower but cheaper.  Maybe the default setting only 
allows 1 output to be active at a time?
