Operation Advanced (DDC/CI) Control Overview
IND100064-52
Introduction
DDC/CI (Display Data Channel/Command Interface) specifies a means for a computer to send commands to the
unit's Display Video Controller to programmatically adjust parameters of the display instead of pressing physical
buttons or navigate through an OSD menu. Specific commands to control units are defined in a separate official
Monitor Control Command Set (MCCS) industry standard. The signal inputs supported are DVI*, HDMI, DisplayPort
(DP) and VGA*.
To determine if your unit has the DDC/CI commands supported as described in this chapter, please review
the "On Screen Display (OSD) Menu" chapter (Service section) in this manual.
It is expected that the user has previous experience of the DDC/CI protocol and how to implement the commands in
their own control applications. A suitable starting point for sending commands, are the GUI operated (or command
line version) of softMCCS software, reference: http://www.entechtaiwan.com/lib/softmccs.shtm
The listed DDC/CI commands below are equivalent to the same functions available in the well implemented Hatteland
Technology Serial/Ethernet Communication Control Interface (SCOM) protocol, where specified, reference:
https://www.hattelandtechnology.com/hubfs/pdfget/inb100018-6.htm
The column "SCOM" is a reference and not part of the DDC/CI commands explained in the table below.
*NOTE: This chapter is an overall description of DDC/CI support for various/selected Hatteland Technology products. References to
VGA (RGB), DVI and Composite may not be present on your product, due to hardware changes/Engineering Change Notifications issued for
Multi Vision Displays (MVD), please check actual datasheet for your model to verify.
