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.
