I just got a 30 inch apple cinema HD display. It is conected to a PNY Quadro FX 560 card. The controls on the side of the monitor for brightness and power operated the first time i tried them but now they do not. According to the monitor manual it is supposed to detect input from the computer and turn itself on (which it does) and turn itself off when computer goes off. But it stays on after the computer goes off. And the brigtness buttons dont work. The little power led on the monitor dost light up. Otherwise the display works fine. Its just stuck on super bright mode. Any clues?
