What winddcutil is
winddcutil is a free Windows command-line utility for querying and changing monitor settings such as brightness and color levels. It communicates through the VESA Monitor Control Command Set over the Display Data Channel Command Interface Standard, commonly called DDC-CI. Its commands can detect monitors, inspect reported capabilities, and read or write VCP feature values. The project provides a standalone winddcutil.exe that runs without installing a Python interpreter. It also describes a Python port using the API from the monitorcontrol package. The 2.0.0 executable was built and tested on Windows 10, and the releases page lists version 2.0.0 from September 15, 2023. The repository identifies an MIT license. Bug reports and feature requests go to GitHub issues, while bug fixes and enhancements are welcomed through pull requests. The listed plan costs nothing.
