Windows implementation of the ddcutil Linux program for querying and changing monitor settings, such as brightness and color levels. Uses the VESA Monitor Control Command Set (MCCS) over the Display Data Channel Command Interface Standard (DDC-CI).

• Good news, winddcutil has been ported to Python! We use the API provided by the monitorcontrol Python package.
• See the CHANGELOG for additional details.

The dist\winddcutil.exe is a standalone executable that can be run without installing a Python interpreter.
