Power-Saver Feature
When the monitor is in normal operating mode, the Power light is aqua-white 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
