I can't get my monitor to turn on with my desktop! I have DIV on both ends of a cable that plugs into my graphics card on one end, and into my monitor on the other end. But my monitor still says "no signal input". Please tell me if I am plugging my cable into the right place, or even if I'm using the correct cable. Also please tell me all possible ways I can fix this problem. Thanks you for your time. Have a good day.
