Knowing The Operating Status Of Your Display - ViewSonic VP2290B User Manual

Knowing the operating status of your display

You can know the status of your display by the color of the power light.
The color of the power light changes from green to amber when your display receives a time-out
video signal from the computer and enters Standby mode to save power. A time-out video signal is
sent from your computer to the display 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 display from the computer.
Refer to the manual shipped with your computer to change the time-out duration value.
