OSD - stands for “On Screen Display”.
The on-screen display is a visual menu that gives users access to multiple setting features.
For instance, on TV, it enables users to arrange the channel order, manage the picture and audio settings, as well as set parental control settings.
Besides TVs, the feature is also available on computer monitors. In most cases, it is accessible through the ‘Menu’ option or an OSD button located on the remote or through control of the front panel.
In view of the abbreviation's technical nature, many users are not aware of this function of their TVs and monitors.
In addition, people that use LG monitors have encountered messages such as OSD locked when they try to change the settings on their monitors.
Users can also unlock the OSD settings on some monitors that don't include the ‘OSD Lock’ option by pressing and holding the Menu button on the front or the side of the monitor for several seconds.
This feature allows users to lock the current settings so that they cannot be accidentally changed.
If the OSD is locked, the warning message ‘OSD Lock’ will be displayed for ten seconds.
It might take up to 15 seconds for the OSD menu to appear.
Note: Allow the display to stabilize for at least 30 minutes before making image adjustments.
The OSD lockout message is the same as the ‘OSD Locked’ message, and it usually occurs when someone has been holding the OSD button for around ten seconds.
Users usually lock the OSD menu to make sure that no additional changes will be made to the settings of their screens.
As we explained earlier, to disable this lock, hold the button for around 10 seconds, and the message should disappear.
