DIAGNOSIS
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 con-
sumption 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”.
Note
If no video signal is input to the monitor, the “NO INPUT SIG-
NAL” message appears. After the delay time has passed, the
power saving function automatically puts the monitor into the ac-
tive-off mode and the indicator lights up orange. Once the hori-
zontal and vertical sync signals are detected, the monitor auto-
matically resumes its normal operation mode.
