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 on page 27.
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, the Power light is amber,
and 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.
