Fix OSD Lockout or On Screen Display Lockout Lock icon.

This tip will be constantly updated to include fixes for as many leading monitor brands as possible.


OSD Lockout or On Screen Display Lockout message is that irritating on-screen message that sometimes pops up when you switch on your monitor. This completely locks all monitor settings.

This problem has most likely happened to everybody at some stage or another. Everything has worked fine until now you turn on your monitor and have a message glaring you in the face displaying something about "OSD Lockout". This doesn't allow you to change any of your monitors settings, including the setting intended to turn off this message. While this problem mainly happens on HP monitors from my looking around I know that others have encountered it on other brands as well. The fixes I provide below should work on those monitors too so don't fear if your monitor isn't an HP model.

The HP Fixes

FIX 1
Plug in the monitor and power it up. Hold down the monitor's 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 a few seconds (just to be sure I'd give it anything around 20-30 seconds) and then try again.

FIX 2
Instead of holding down the Power button, turn on the monitor and hold down the Menu button for 10-20 seconds. This should unlock the OSD.

FIX 3
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 4
The Menu button may be stuck in a pressed in position. To get it "unstuck" you'll usually need to open up the monitor. If your not a seasoned veteran at opening up electronics (and knowing where all the screws go back into) then this could be tricky unless you know what you're doing. Unfortunately there are too many models of monitors for me to give a step by step instruction guide for you. If you have warranty this is where you should use it, I suggest you contact the manufacturer.

Monitor display says OSD Lockout /no signal input how to fix this?


This document pertains to LCD monitors .
One of the following messages appears on the screen (over the items being displayed).
OSD Lockout
OSD Lock-out
... or similar message.
This message occurs when the Menu button on the front panel is pressed for more than 10 seconds. OSD lockout prevents the OSD menu from opening on the screen when a button is accidentally pressed.
NOTE: The button may be different and the procedure might vary on some monitors. Please check your monitor User Guide to find the exact procedure if this procedure does not work.
To remove the OSD Lockout message, release the Menu button (if something was pressing against it), and press and hold the Menu button again for about 10 seconds - until the message goes away. If the OSD Lockout message does not go away, the button may be stuck or the hardware behind the button might have become defective.

All computer monitors, whether they are LCD or CRT style, have a built-in feature called the on-screen display (OSD) lockout that prevents users from viewing any images on the monitor. If your computer screen has accidentally been set to the OSD lockout setting, there are several ways you can remove the lockout.

Power off your computer and then remove the monitor cable from the port on the back side of the computer case. Reattach the cable and make sure the pins are correctly screwed in. Power the computer back on and check to see if the OSD lockout message is still being displayed. Check the manual that came with your computer or monitor and locate the troubleshooting section if you are still receiving the OSD lockout message. Find the OSD lockout heading and read the method that your particular model uses to remove the lockout. Attempt generic lockout removal procedures if you no longer have the manual that came with your monitor. Press and hold the "Menu" button located at the bottom of your monitor for 15 seconds and wait to see if the OSD lockout message disappears. Press the "Menu" button again if the lockout message remains on the screen. Use the arrow buttons to navigate through the main menu options. Highlight the "Settings" or "OSD Menu" option and then hit the Menu key again to access the new list of settings. Scroll down to the "OSD Lock" heading. Use the arrow keys to change the setting to "No." Hit the Menu key again to return to the main menu. Scroll to the "Exit" setting and then hit the Menu key a final time to exit the menu setting and remove the OSD lockout.
