Power Management System
This monitor incorporates new circuitry for lowering energy usage
during idle time, following the Display Power Management Signalling
(DPMS) guide lines of the Video Electronics Standards Association
(VESA), and is certified as exceeding the EPA's Energy Star program
for reduced power usage.
For the power savings feature to operate, the monitor must be used with
either a PC having power saving circuitry. The monitor has three power-
saving states, and the power saving operation is indicated by the power
indicator on the front panel.
When the power indicator is green, operation is normal. When the
power indicator is Amber, the monitor is in a power saving mode.
If the power indicator is Amber, press the power button to turn on the
monitor. If the power indicator is Amber and you wish to use the PC
again, move your mouse pointer or touch a keyboard button. When the
monitor is not in use, save energy by turning it off.
