I think you mean that you want more than one monitor hooked up. Now both of your monitors just display the same image (correct?). The only way to make both monitors work together would be to add a graphics card.
You got it. thats what im trying to do. So i need a graphic card. Ok I have a Hp Pavilion Desktop Pc. Like I said, i dont know to much about these things, only how to do my work on them. So what kind of graphic card would i need for this?
