CONNECTING THE SIGNAL CABLE AND POWER  
CORD  
POWER MANAGEMENT SYSTEM  
If you use the monitor with a computer that complies with the  
power-saving program, you can set the monitor to go blank when  
the system has remained unused for a period of time. To specify  
the period or to disable this feature, set the system timeout field  
of the computer’s system setup program or use special software  
for power-saving. See the computer user’s manual for the details  
of using the system setup. While the monitor is in power-saving  
mode (blank screen), it consumes less power than when it is in its  
normal state. The color of the power LED will indicate the state.  
To restore the screen image, press any key of your keyboard or  
move your mouse. If the signal cable is connected loosely or  
disconnected, the power-saving feature will not operate.  
1. Turn off the computer and monitor.  
2. Connect the 15 pin D-sub connector to the output port of the  
video card in your computer.  
3. Tighten the screws of the connector.  
4. Plug the power cord into the AC receptacle located on the back  
of the monitor.  
5. Plug the other end of the power cord into the AC outlet.  
DISPLAY DATA CHANNEL FOR PLUG AND PLAY  
If you use the monitor with a computer that complies with  
DDC1/2B/CI of VESA, the host video card automatically  
configures itself without your intervention in a way that best fits  
the attached monitor. The Display Data Channel(DDC) allows  
the monitor to inform the host system about configuration  
information for optimum use of the monitor. Use of the video  
card utility is not required to match the resolutions and refresh  
rates of the monitor and video card.  
Signal Cable  
Power Cord  
If your power cord is PC-to-Monitor type, plug the other end  
of the power cord into the AC receptacle in the computer.
