Hi,

To unlock the On Screen Display (OSD) lock, hold down the menu button for 20 seconds until OSD unlocked shows on the screen.

Please rate my answer if this helps,

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 ten 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.



OSD stands for "On Screen Display." It is an onscreen configuration menu included with various monitors. When you press the MENU button or one of the other buttons on the front or side of a monitor, the onscreen display may appear. The OSD typically includes monitor calibration options, such as brightness, contrast, and color adjustments. Some OSDs may also include horizontal and vertical position controls as well as tilt and keystone adjustments.
If you can't make adjustments to the monitor settings using the OSD interface, the onscreen display may be locked. You may also see the phrase "OSD Locked" appear when you try to change the settings. Some monitors include an option within the menu called "OSD Lock", which you can turn on or off. If this option is available, simply turn OSD Lock off and you will be able to make adjustments to the settings.
If your monitor does not include the "OSD Lock" option, you may be able to unlock the OSD by pressing and holding the MENU button on the front or side of the monitor for several seconds. If you try this method, be patient! It may take up to 15 seconds for the OSD to unlock.

OSD Lockout prevents changes being made to the monitor through the use of the front panel buttons. When the OSD is locked, pressing a button from front panel displays OSD Lock-out for about 10 seconds. You can quickly remove the OSD Lockout message by pressing a front panel button again. To unlock the OSD, press and hold the Menu button until the Main menu displays, about 10 seconds. To lock the OSD, press and hold the Menu button until an OSD-Lockout message displays, about 10 seconds.

@ baller98_199; did you ever get a solution to this? I'm having the same problem with the same monitor!

possible faulty VGA Controller board.

This is a "feature" they include to prevent accidental changes to the screen setup. You should be able to unlock the OSD by pushing the Menu button and the right arrow button together for about three seconds. The message "controls unlocked" should appear.
