An on-screen display (OSD) is a control panel on a computer monitor
or television screen that allows you to select viewing options and/or
adjust components of the display, such as brightness, contrast, and
horizontal and vertical positioning.
On
a computer monitor, an on-screen display is usually activated by
buttons on the bottom of the monitor. As an example, one button may
bring up a display of the brightness
and contrast levels, which may be adjusted by pressing the monitor's up or down arrow buttons.
On
a television screen, an on-screen display can usually be activated
either through buttons on the television set itself or through the
remote control. Television on-screen displays are becoming increasingly
complex and interactive. In addition to the visual calibration options,
the on-screen display may allow you to view program information, search
for programs, or put certain channels under parental control.
