 DDC (Plug & Play)
This monitor supports the VESA DDC (Display Data Channel) stand-
ard.
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
monitor.
There are many varieties of DDC due to the differences between
systems. This monitor works with DDC1 and DDC2B.
