When there is no video input signal this monitor, following a time-out period, will
automatically switch to an OFF mode. This reduces the monitor's internal power supply
consumption. After the video input signal is restored, full power is restored and the display is
automatically redrawn. The appearance is similar to a “Screen Saver” feature except the
display is completely off. The display is restored by pressing a key on the keyboard, or
clicking the mouse.
