Implementation The easiest/quickest way to implement control of the DDC in a Windows environment application is to use a library designed for this task. An example of such a library is the WinI2C-DDC. “WinI2C/DDC is a professional tool that allows you to control display devices in the Windows environment via the DDC/CI protocol.
