I have the same problem with dual Monitor configuration.
I'm using the Gigabyte Board Q77M-D2H with the 3rd Generation i3 (3220) and the latest HD Driver (9.18.10.3165) running Win 7 x64.
When disabling and enabling the Display Adapter the second display is recognized. After reboot it is again not detected.
On my system the display which is connected via HDMI (HDMI to DVI cable) is the primary device and always active and the second display which is direcly connected via DVI is not detected after reboot.
Is this a problem of the driver or chipset, as this occurs on different HW platforms? Will there be a fix available?
