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: The Menu button may be stuck in a pressed in position. To get it “unstuck” you’ll usually need to open up the monitor. This could be tricky unless you know what you’re doing. Unfortunately there are too many models of monitor for me to provide detailed instructions. If you have warranty this is where you want to contact the manufacturer.
