==Bug detailed description==
-----------------------------
I'm not sure whether or not this is a real bug, anyway I submit it for
tracking.

When I connect DVI monitor with DP-DVI adapter cable to DP port of DUT,
"testdisplay -i" shows that a "HDMI" port is connected.

==Reproduce steps==
---------------------------- 
1. Connect DVI monitor with DP-DVI adapter cable to DP port of DUT and Boot
2. "testdisplay -i" shows:
Connectors:
