You can only use DVI or HDMI, but not both at the same time. The bios will enumerate whatever connectors are connected at boot time. You cannot switch them on the fly. The phantom VGA detection should be fixed in kernel 3.1 with fixes showing up in the stable series kernels as well. You can only have two connectors in use at the same time. The ones that you can use must be connected at boot time. If you want to use DVI and HDMI, you have to connect both of them at boot time and the oem has to have wired up the board to allow it. Check your owners manual to see what combinations are supported simultaneously. |

Hello, The connector list is wrong on my system (amd A8-3850 with integrated radeon hd 6550d). My system have got VGA, DVI and HDMI connectors. The VGA connector is always reported as connected by xrandr (connected or not). I deactivated this one with kernel parameters video=HDMI-A-1:e video=VGA-1:d. The DVI connector appears as HDMI-0. The HDMI connector is absent (When I connect a monitor to this one, HDMI-0 becomes this output and the DVI output is lost).
