How do I add a VGA monitor to a computer that already has two DVI monitors? I want to add a Dell monitor (it's VGA circa 2005) to my computer. My graphics card has the 2 DVI female ends (that are currently being used by my two existing monitors), 1 display port, and 1 HDMI. My Motherboard has D-Sub +DVI, 1 HDMI, and 1 VGA. Also, my CPU claims it can support three monitors. Any ideas on how I can hook up this third monitor? Thanks.
