This has most likely annoyed many of you at some point. You turn on your monitor one day and see a jeering message telling you something about an “OSD Lockout”. It doesn’t allow you to change any of your monitors settings, including the setting intended to turn off this message. While I’ve only seen this error on HP monitors I know that others have encountered it on other brands as well. The fixes I provide should work on those monitors too. (Note: OSD stands for O n S

creen D isplay.)

Fix One:

Plug in the monitor and power it up. Hold down the Power button until you get a message saying “OSD Unlocked”. If the problem persists after OSD is unlocked then unplug the monitor from the wall, wait 20 seconds and try again.

Fix Two:

Turn on the monitor and hold down the Menu button for 10-20 seconds. This should unlock the OSD.

Fix Three:

Turn off the monitor, press down the Menu button and then turn on the monitor. Wait 10-20 seconds. This should unlock the OSD.

Fix Four:
