 THE ANALOG RGB INPUT CONNECTOR PIN
 21-pin Euro-SCART terminal (RGB)
 POWER MANAGEMENT
The monitor is based on VESA DPMS (Display Power Management
Signaling).
To activate the monitor’s power management function, both the video
card and the computer must conform to the VESA DPMS standard.
 DDC (PLUG & PLAY)
This monitor supports the VESA DDC (Display Data Channel) standard.
DDC is a signal standard for carrying out Plug & Play functions on the
monitor or PC. It transfers information such as degree of resolution
between the monitor and PC. You can use this function if your PC is
DDC compliant and if it is set so that it can detect the Plug & Play mon-
itor.
There are many varieties of DDC due to the differences between sys-
tems. This monitor works with DDC1 and DDC2B.
