POWER SAVING FUNCTION
If your PC has a VESA DPMS (Video Electronics Standard Association, Display Power
Management Signaling) power management function (energy-saving mode), your monitor will fully
support this function. The monitor has a four-stage power management system.
Stage ON
Power indicator glows green
Function Monitor operating

Power normal
consumption < 140 W
If your PC detects inactivity (no input) it sends an appropriate signal to the monitor to reduce the
power consumption. The power indicator of the monitor changes color to indicate the status change.
If there is still no input, power consumption is further reduced (OFF mode).
Once an input is made at the PC the screen contents are redrawn and full power is restored.
The length of the individual stages is determined by the power management system of the PC. For
detailed information on how energy-saving mode operates refer to the Operating Manual or
Technical Manual of your PC.
The service life of your monitor will be extended if the OFF mode is switched to after
i
30 minutes at the earliest (setting in screen saver, in your PC's BIOS setup or in the OSD
menu).
When the monitor is switched to OFF mode by the power management system a power
consumption of about 3 W is maintained to feed the circuit for redrawing the screen
contents.
To cut off power consumption totally, press the ON/OFF switch on the front of the monitor.
