An on-screen display (OSD) is the graphic image, text, or information shown on TVs, cameras,  monitors, DVDs, and VCRs. It is used to show information about the image in order to modify screen display options and to make changes to the operation of the device itself. The on-screen display option is usually activated by a menu button on many electronic devices. This display option can be used to display complex menus with multiple choices such as contrast, volume, vertical or horizontal positioning, etc.
