I have a dual boot Windows 7/Ubuntu system with 3 monitors.
1 VGA, 1 DVI-D, 1 HDMI
I read about it and I saw that there is a lot of talk about Display port.
The monitor that is connected to the HDMI port of the graphic card has a passive HDMI to DVI-D dongle because the monitor itself is DVI-D.
The manufacturer is MSI, it is R6770 Graphic card
I would guess that one of the port is internally a display port because all 3 monitors are working fine under Ubuntu.
But under Windows 7, only 2 monitors at a time are working.
I must be missing something simple, but I've been trying for a couple of hours now and I can't figure out.
I'm not an expert in Windows but I know my way around.
Any help would be appreciated but keep in mind that all 3 monitors are working fine in Ubuntu,
