Power-Saver Feature
When the monitor is in normal operating mode, the Power light is blue and the monitor
uses the normal watts of power. For power usage, refer to "Technical Specification"
(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.
