This is an odd one. After a Dell U2412 LCD had been placed on its face to connect cables, the screen became locked. After some research this apparently happens when the MENU button is held in for 15 seconds. So monitors like the Dell E228WFP, P2210 and 1701FP can be unlocked by holding the MENU or SETTINGS button for 15 seconds.
The question is, what about the more expensive programmable LCD’s like the 2412… they have four programmable buttons. The answer is to press and hold the BOTTOM button (not the power button) for 15 seconds.

Hello everyone who own the D2719HGF and are facing this same issue. I found this thread via DuckDuckGo.
Here's how you fix this and unlock the power button:
Press the Enter button
Press the Left Arrow button and choose the Reset option in the OSD menu
Press the Right Arrow button to select YES
Press Enter button
Your monitor will reset to the defaults and all options are unlocked.

My DELL monitor 1907fpvt I unlocked using steps:
1. press and hold menu button
2. simultaneously press and hold power button
Keeping this two buttons pressed wait for unlock. Opened padlock will be displayed.
I spent a lot of time trying to solve the problem, checking combinations from internet. Finally this one combination I found just by trial and error.

A laptop screen would be unrelated to this solution. If you can describe what you are seeing (EXACT TEXT of messages, when it started...) we can help.
