Knowing the operating status of your display

You can know the status of your display by the color of the power light.

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.
