No display on 3rd screen on boot up?

post #1 of 4
Thread Starter 
Hi,

I have 3 screens (2 x Samsung SA20B300, 1 x BenQ 21"), one of the samsungs is connected by an active mini displayport to dvi adapter + dvi cable, the other is a normal dvi cable and the benQ has a HDMI to DVI adapter and a HDMI cable. They are all connected to my Gigabyte HD 7950 OC edition. The screens are set up as: Samsung - BenQ - Samsung.

But, when my computer boots, it gets past the OS loading screen and the monitors go black and stay that way. If I move the mouse the cursor moves across two of the screens (HDMI and DVI) but the active mini displayport - dvi adapter screen goes into standby mode and the only way I get picture back is if I unplug the MDP adapter and reboot with it out, then plug it back in once I get to the log in screen.

Any help with this would be greatly appreciated, I can't figure out what is going on.
