7 Power Management
This monitor features a power management system to “power down” upon receipt of the
display power management signaling (DPMS) from a DPMS video card.
To conserve energy and extend monitor life, this monitor automatically starts a power saving
mode when the input signal disappears (such as when a PC enters sleep mode). The power
saving mode is active when the LED on the Power button switches from green to red and
normal operation resumes automatically when the input signal is restored.
The monitor enters an appropriate mode through identifying each of the modes of the
signaling system.
7.1 Power Consumption

Unsupported mode (green), and Standby/Power Off (red).
