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” (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 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 PC for this feature to work.
Refer to your computer documentation for instructions on setting 
energy-saver features (sometimes called power management 
features).
The energy-saver feature works only when the monitor is connected 
to computers that have energy-saver features.
