    I recently installed a second monitor for my PC. I have an AMD 7850 and one display is a DVI output (my primary and previously used display) and the new one uses an hdmi output. When I first tried this, it worked completely fine but now, when I boot to windows the computer doesn't output a display when both are connected.

    The computer is booting to windows succesfully, though, as the num lock key works and I can shut down the computer with out hard killing the power. If I boot with only the DVI monitor everything is fine and, after I have booted to windows, I can then connect the hdmi and both displays work.

    Any ideas as to why this might be happening? Is there some way to choose a primary display port on the video card? Thanks for the help.
