Hi, I have this annoying problem with my dell monitor that a lock keeps apearing in the middle of the page and sometimes it appears unlocked. Can anyone advise me as to how to get rid of this very annoying problem, so that I can enjoy my computer again ??
I had this problem once - all you need to do to unlock the controls is press and hold the Menu button for about 10-15 seconds. That should unlock all of the controls. It took me days of hunting through Dells website to find this when it happened to me! * 2 years ago
