Some computer systems are not compatible with the DDC standard. If your monitor is displaying the wrong resolution, check your computer system for a DDC compatible video card and contact the Service Center.

Do not open the monitor. There are no user- serviceable components inside. There is dangerous high voltage inside even when the power is off. If the display monitor does not operate properly, remove the power cord from the wall outlet and contact your dealer. Careless use and unprofessional maintenance can cause serious electrical shock and other hazards.

SECTION 3:

OPERATION

3.1POWER MANAGEMENT

This monitor is equipped with DPMS (Display Power Management Signaling) function which automatically switches to power saving mode (less than 5 watts consumed) when the computer is left unattended. Although the monitor can be left in power saving mode for longer periods, it is recommended that you turn it off after your daily work.

The DPMS function requires support from the computer system of any software DPMS function currently being used. If the keyboard (or mouse) is left unattended for a certain period, the program or system will set the sync signals to SPMS modes. The DPMS function has three states. Recommended signals, power consumption, and recovery time are shown in the table below:
