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 Specifications on page 24.
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.
