I own a DH77DF-based system and two identical monitors (Fujitsu-Siemens P19-2) with only VGA or DVI input.
I would like to run a dual-monitor setup in Windows 7 64 Bit.
DVI to DVI on screen 1
HDMI to a HDMI-DVI adapter on screen 2
Both monitors show the same content during POST and while Windows says it is loading.
As soon as the logon screen appears on screen 1, screen 2 loses its signal.
I cannot find screen 2 anywhere in the Display Options. It just acts as if no second monitor is connected.
Updated to the latest Graphics driver today.
Any ideas what is wrong with Windows?
Best regards and thanks for your help!
Be sure to be using the latest BIOS posted here:
Then install the latest video driver here:

If the issue persists, test using only the display connected to the HDMI port. Additionally, you may need to test a direct connection between the HDMI port and another display as the issue may be caused by the adapter/converter that you are using.
