my motherboard is biostar A55ML+, processor is AMD A4 3400, and Sapphire HD 6450 graphics card

my first VGA monitor is connected to the onboard VGA of the motherboard, and dual graphics is enabled

where do i connect my second VGA monitor? by the way the first VGA monitor must be connected to the onboard VGA of the motherboard to enable dual graphics, i tried connecting the 2nd monitor to the VGA of the, separate graphics card, but it doesn't display anything

what do i do?

I'm using Intel HD4000 and have to set the North Bridge option to onboard in BIOS to enable both integrated and dedicated graphics on two monitors. One montior gets the integrated and the other gets the dedicated.

When using a single monitor I have  to switch back and fourth between Integrated and PCI-e in BIOS. Wish there was  another way. I thought the Luicic Logics LicidMVP software would allow switching from within Windows, but not with my system. You may be luckier with an AMD system.
