If the display is correct, you either have a faulty video cable, a faulty video cable connection on your motherboard or monitor, or a faulty LCD screen. If the display is the same as the laptop screen, you either have a GPU problem, more likely a CPU problem since they are integrated, or a motherboard problem.
