I have a Dell UltraSharp 19-in Flap Panel monitor. The settings on the monitor are some how locked. I want to be able to adjust the settings on the monitor using the controls on the front. If you press one of the settings buttons on the front of the monitor a picture of a purple 2-inch square with a white lock comes up in the middle of the screen. I can't get passed that.
I know I can you the OS to adjust the display, but I want the buttons to work.
I see a picture of a lock symbol on the back of the monitor with a small rectangle hole next to the symbol. Is this to put a lock on the screen so someone doesn't steal it, or is it or is there like some reset button or some way to lock/unlock the controls?
Note: I didn't get this monitor from dell. It does not have an express service code tag number on it or anything like that.
