Technical Supportfaq | Memorex MM1740 instruction

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.
