Using Power Management
The LCD monitor follows the VESA approved DPM Power
Management function.
The power management function is an energy saving
function that automatically reduces the power consumption
of the display when the keyboard or the mouse has not been
used for a fixed period.
The power management feature on your new display has
been set to the “ON” mode. This allows your display to enter
a Power Saving Mode when no signal is applied. This could
potentially increase the life and decrease the power
consumption of the display.
Selecting a video source
To view a video source:
Use the input button to set [VIDEO].
Use the COLOR SYSTEM menu to set [AUTO], [NTSC],
[PAL], [SECAM], [PAL60], [4.43NTSC], according to your
video format.
