How to know if DVI connection is digital or analogue?
DVI supports both digital and analgue connections (that's how VGA
adaptors work). I have a user who fought with his Windows drivers to
force digital connection, even though he was connecting with the DVI
ports over a DVI cable it was sending analogue until he configured it
properly. Not that he is running a Debian derivative, how can he check
which connection (digital or analogue) is being used?
Notice that he can't actually _see_ and difference on the screen :)
But it is important to him to know that it is in fact digital.
