Monitor Specifications  
The following sections give you information about the various power management modes and pin assignments for various connectors for your monitor.  
Power Management Modes  
If you have VESAs DPMS compliance display card or software installed in your computer, the monitor automatically reduces its power consumption when not in 
use. This is referred to as Power Save Mode. If input from keyboard, mouse or other input devices is detected by the computer, the monitor will automatically 
wake up. The following table shows the power consumption and signaling of this automatic power - saving feature:   
Activate the computer and wake up the monitor to gain access to the  OSD .
