This monitor meets the power-saving guidelines set by
VESA and Energy Star, as well as the more stringent
NUTEK .
If the monitor is connected to a computer or video
graphics board that is VESA DPMS (Display Power
Management Signaling) compliant, the monitor will
automatically reduce power consumption in three stages
as shown below.
You can set the delay time before the monitor enters the
power saving mode using the OSD. Set the time according
to “Setting the power saving delay time” on page 16.

Note
If no video signal is input to the monitor, the “NO INPUT
SIGNAL” message (page 20) appears. After the delay time has
passed, the power saving function automatically puts the monitor
into the active-off mode and the u indicator lights up orange.
Once the horizontal and vertical sync signals are detected, the
monitor automatically resumes its normal operation mode.
