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 DDC2B.
