This monitor supports the VESA DDC (Display Data Channel) standard.
DDC is a signal standard for carry ing 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 va rieties of DDC due to the d ifferences between sys tems. This monitor works with DDC1 and DDC2B.
