Power Saving Function
This monitor meets the power-saving guidelines set by
E S
VESA and NERGY TAR, 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.

Notes
When your computer is in a power saving mode, MONITOR IS IN
POWER SAVE MODE appears on the screen if you press any
button on the monitor (page 15). After a few seconds, the monitor
enters the power saving mode again. Once the horizontal and
vertical sync signals are detected, the monitor automatically
resumes its normal operation mode.
