    any monitor manufacture will work. You'd just need the connector to an external one.

    ok so if it doesnt display it onto the the monitor its the mother board but i was looking where display is under that plastic there is like long chip i forgot what they call taht chip for mac i mean i can get it for you it basically hooks it up from the screen to the mother board i think right by the heat sink could that cause problems by chance?
