Auto adjustment is locked on Samsung monitors

Another problem, solution of what i faced today. This tip will help you to unlock your monitor settings adjustment. It works with Samsung monitors, if you can’t change any of the setting on your display using external buttons and get the message “Locked/Auto adjustment is locked” try holding menu button for a 5 seconds. Menu will dissappear and after that you can change your settings once again.
