Power-Saver Feature
When the monitor is in normal operating mode, the Power light is green and the monitor uses the normal watts of power. For power usage, refer to "Technical Specifications" (Appendix B).
The monitor also supports a power-saver mode that is controlled by the computer. When the monitor is in the reduced-power state, the monitor screen is blank, the backlight is off, and the Power light is amber. The monitor uses minimum power. When the monitor is "awakened," a brief warm-up period occurs before the monitor returns to normal operating mode. The energy-saving reduced power state activates if the monitor does not detect either the horizontal sync signal or the vertical sync signal. The power-saver feature must be activated on your computer for this feature to work.
Refer to your computer documentation for instructions on setting energy-saver features (sometimes called power-management features).
NOTE: The energy-saver feature works only when the monitor is connected to computers that have energy-saver features.
