Checking the operating status of your monitor
You can check the status of your monitor by the color of the power light.
The color of the power light changes from green to amber when your
monitor receives a time-out video signal from the personal computer or
workstation and enters Standby mode to save power. A time-out video
signal is sent from your personal computer or workstation to the monitor
when the former detects inactivity on the keyboard or mouse for a set
duration of time. You can change the time-out duration for your monitor
from the personal computer or workstation. Refer to the manual shipped
with your personal computer or workstation to change the time-out
duration value.
