How would you do this? I don't quite understand what each port does. The way I thought of it is kind of dividing the ports on the back into columns and rows. The first column is Computer A, second column is Computer B, 3rd is output. 1st row is something (im not sure), second row is monitor. 3rd row is keyboard. Is that right? so if you go to 2nd column 2nd row that would be for computer b's screen? Whats the first row for?
