Troubleshoot computer screen locking tutorial

computer screen locked up how to solve

Problem Show:

My monitor has been like this for several days, the word "screen control lock" appears when you press the power button.

End

Problem solving:

First find a "OK" or other menu key (menus) in the place where the screen control key is located (different brands of monitors are not the same).

Hold down the menu key for 5 seconds or 12 seconds, and you can press it for a longer period of time.

Press and hold until a black window appears showing "screen control unlocking" as shown in the figure.

Now press the power button and turn the monitor back on.
