The DVI connector on a MacBook Pro is a Dual Analog / Digital output.
Why is it dual? Can it drive two displays?
I'm not talking about the F7 Mirroring function...
I'm talking about the fact that there connector looks like its capable
of driving two DVI displays.
If in fact it can only drive one display which channel of the DVI
output is actually being driven?
Or is it smart enough to know which one is connected and drive it?
