That's no more than an idea, but did you check the monitor type settings (IGD Primary Video Port and IGD Secondary Video Port) in the BIOS ?
If you are using the DVI-I connector the setting must match the monitor type Analog or Digital.
I suspect that the standard MS VGA video driver does not take this setting in account but the Intel one does.
