Laptop Screen Height and Width
Please help. I just got a laptop and this morning everything was fine. Now, when I turned it on, the whole screen like shrunked into the middle of it and there's all this black space like 5 inches thick. Can anyone help me?? I need to change it back quickly to fullscreen which will take up the entire LCD display. What function key or keys do I use to put it back to normal? Please respond ASAP!!!
