I am attempting to run dual monitors on the onboard graphics via HDMI and DVI. It detects each monitor perfectly fine separately in either port, but it won't pick them up together. Google said change the setting in BIOS using Advanced>Chipset Configuration > IGPU Multi-Monitor or in the North Bridge Configuration but I don't have the chipset configuration option. There is also no multi-monitor option anywhere else in the BIOS.
Detect using Windows display settings doesn't pick the additional monitor up.

Why can't I see this option and how do I work around it?!

Sorry if this is in the wrong section!
