I am purchasing a new Dell system with a 20 inch FP monitor. I have an existing Dell 2001FP monitor and I want to use both them in a dual monitor setup. I know I need a stand alone video card. Once I do that, how do I connect the 2 monitors -- to 2 different ports on the card (does my old 2001FP have the right kind of port) with 2 cables? If 2 cables, what will I need to buy besides what comes with the system (or what I have from my existing monitor & system)? Thanks.
