When I turn on my monitor, the auto adjust kicks in and the screen turns black. I can turn the screen off and back on, the screen is visible for couple of seconds, and it turns black again. I had this problem a month or so back, and I pressed and held a combination of buttons for a few seconds and it seemed to turn auto adjust off, but now I can't remember what keys I held in and none seem to work now. Can someone PLEASE tell me the combo to turn this auto adjust "feature" off????
