This article provides information about the On Screen Display (OSD) menu of the Elo 2210L, 22-Inch Non-Touch Monitor. 

All monitor adjustments made through the OSD are automatically memorized as the ’Source button’ and ‘Menu button’ are pressed.
This feature saves you from having to reset your choices every time the monitor is unplugged or powered off and on. If there is a power failure, the monitor settings will not default to the factory specifications.
