I recently purchased a 23 inch widecreen lcd Acer monitor and I'm actually not sure how to go about the ports. My old monitor just had a vga plug in and that was it. With the new monitor I have HDMI, dvi-d in, vga in. My graphics card has two slots that fit for the dvi-d connector. Also the graphics card came with a head attachment that converts the standard vga to a dvi-d slot. My question is do I use both of these and connect both the vga in and dvi-d in to the graphics card? I figured I do connect the hdmi, but wasnt sure if dvi-d and vga are basically pick one or the other. Any help as to how these work and what specifically they do would be great. Thanks
