I have two Dell 24" FPD monitors that I would like to connect to my computer and use them independently (as opposed to extend the display or duplicate the display). My computer is a Dell Dimension XPS 420. Do I need a new video card for this type of setup and if so, what type of video card will fit my computer?
I do not think this is possible. You have one computer with one operating system. Even if you add a video card, it is still just one operating system controlling both video cards. Maybe I don't understand the question?
