The following site has step by step instructions on steps you can try: http://www.ehow.com/how_5008634_fix-lockout-display-computer-monitor.html
I'll paste them below: All computer monitors, whether they are LCD or CRT style, have a built-in feature called the on screen display (OSD) lock out that prevents users from viewing any images on the monitor. If your computer screen has accidentally been set to the OSD lock out setting, there are several different ways you can remove the lock out, depending on the make and model of your particular computer monitor.
1 Power your computer completely off 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 all of the way. Power the computer back on and check to see if the OSD lock out message is still being displayed.
2 Check the manual that came with your computer or monitor and locate the troubleshooting section if you are still receiving the OSD lock out message. Find the OSD lock out heading and read the method that your particular model of monitor uses to remove the lock out. Follow the instructions to remove the lock out.
3 Attempt generic lock out removal procedures if you no longer have the manual that came with your monitor. Press and hold the "Menu" button located at the bottom end of your monitor for 15 seconds and wait to see if the OSD lock out message disappears.
4 Press the "Menu" button again if the lock out 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.
5 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 over to the "Exit" setting and then hit the Menu key a final time to exit the menu setting and remove the OSD lock out.

OSD Lock
The OSD can be enabled or disabled by pressing and holding the Menu button on the front panel for 10 seconds. If the OSD is locked, the warning message OSD Lock displays for 10 seconds.
If the OSD is locked, press and hold the Menu button for 10 seconds to unlock the OSD.
If the OSD is unlocked, press and hold the Menu button for 10 seconds to lock the OSD.
plz do rate the solution if helped

Here you go!
From Dell website:
'OSD Lock': Controls user access to adjustments. When 'Yes' (+) is selected, no user adjustments are allowed. All buttons are locked except the menu button.
All buttons can be locked or unlocked when the 'Menu' button is pushed and held for over 15 seconds. See more here:

Turn off monitor, hold down the menu button, turn the monitor back on, release the menu button after 10-20 seconds. Your Iiyama screen will now be unlocked.

You may wish to try this (my model AOC g2016wa2)
1. push MENU button
2. scroll to Advanced
3. push MENU button
4. scroll to Factory recall
5. push MENU button
It resets the power button locked setting but you lose all other settings.

On the monitor there is a menu button. Press and hold down on the Menu Button for approx. 10 seconds until you see the menu. This unlocks it. If you care to lock it again, just do the same thing. For the record, I have a HPw2207 monitor. Hope this helps. Jim

my moniter was automatic restarted, and osd lock not open,where is is osd open option?

that depends on the brand and model of monitor ,
it normally takes 2 buttons pushed at same time to unlock it.
if you have side buttons its normally them.
