Periodically, when the monitor comes up from standby, it opens to 800 X 600 resolution instead of the standard resolution. This does not happen all the time but does happen often. If I disconnect the monitor from the computer (MacBook Pro)  and then reconnect it, the display reverts to the standard resolution. I think this may have started happening when I upgraded to OS-X Mountain Lion. Can anyone suggest a fix so that it always comes up in the standard resolution (1920x1080)?
