What is the result of connecting a single link (DVI-D) video source to a dual link monitor?

I too have had good results using the miniDisplayPort to VGA adapter. 
With most VGA monitors this setup "just works". In fairness to Apple the 
application space I'm trying to get working uses esoteric hardware. Not 
many users will be using $25k monitors and you wouldn't really expect a 
Mac Mini to work with these very high resolution monitors. Still, I've 
got at least  one  3MP monitor working at its rated  resolution and I'm 
hopeful with a bit of work  to get  a couple of others working. My 
client wouldn't have a problem purchasing a Mac Pro if that proves to be 
necessary and with some assistance from the Apple folks I believe we can 
make that setup work. In this application (Radiology) the computer 
systems are only a small fraction of the cost of the setup.
