The usage of video adapters like DP to DVI or DP to VGA is not supported by the Intel Graphics Controller
I recommend trying straight cables, such, DVI to DVI or HDMI to HDMI and Display port to Display port.
i think you need a ACTIVE Displayport Adapter. if you want use 2 display on intel hd graphics 4000.
I'm new on the forum, and recently built a new PC based on Z77 and I'm having issues with the HDMI and DVI outputs.
I'm no longer able to view anything on my monitor after installing the Intel HD 4000 drivers.
Before that, I was able to sucessfully installing the Win 7 x 64 using HDMI High Speed straigth forward cable.
Mother MSI Z77 GA-55 (latest firmware. 1.5)
