The middle output is for a S-Video cable. I think it's better than coaxial cables, and depending on the TV, you can connect it there. A good way to check would be to see when changing the TV mode from channels to Video 1 and Video 2 would be to keep changing it and see if there is a mode called S-VHS, that is S-Video and your TV should have the input for it. The other output is a DVI output. It's for newer monitors that can use a digital signal instead of the old analog signal that is on the left. There's an adaptor for that signal if you wanted to run dual monitors with analog monitors only.
