GTX 660 Ti won't run 2 displays :(

I just picked up a EVGA GTX 660 Ti Superclocked. I plugged monitor 1 into the DVI-I connector with an adaptor. It works fine. I plugged monitor 2 into the DVI-D connector with a DVI-D to VGA adaptor. Now I understand that the DVI-D is digital only but kinda figured that's what the adapter was for. The monitor DOES have a DVI-D plug in the back so it does have digital capabilites. I just don't have a digital cable.

Anyway.... SHOULD monitor 2 work when I plut the VGA cord into a DVI-D-VGA adapter? Or will I HAVE to use a DVI-D cable because the adapters are just a farce?

Thanks,

Rob
