Perhaps it *is* relevant, then, that when monitors are connected to VGA and DVI, both are activated (in mirrored mode) by the BIOS, but when monitors are connected to HDMI and DVI, *only* the HDMI-attached display is activated by the BIOS. > Perhaps it just doesn't have a SOR[3]/DAC[1]?

This computer is in my office, and I need to go home shortly, but I will be able to do further experiments tomorrow morning. -- You are receiving this mail because: You are the assignee for the bug.
