I'm really not sure. I have 2 dell computers, one has the dual video card which enables me to have two monitors to the one computer the other cpu only has the video card for a single monitor. I have the split cable that plugs into the back of the computer with 2 separate connectors, one for each monitor. I need to be able to do the same thing with the other cpu, I want to use the smaller one for storing all my pictures that I take and the bigger one for school etc. I need to be able to run both computers at the same time if I can also, I have a splitter that will enable me to hook up both cpu's. I am way new to this, I always had my IT guy to work this stuff out for me before I got laid off, now I'm on my own.
