I own a MacBook Air 13" (bought in 2012), and I have recently been given a computer screen which I would like to use my MacBook with. However, I did not get any cords with the screen, which is a HP 1825 (an 18" LCD), regulatory model P4830, product# P9021B. I also have Apple's Mini DisplayPort to VGA Adapter. I know I am missing cords to connect the screen to my laptop, but I am unsure as to what I have to buy. Any advice would be very appreciated (and I would be happy to provide more specific information if it is needed; I only noted what I thought would be relevant, but I am obviously no expert).
