ddcutil is a Linux command-line tool and shared library (libddcutil) for querying and changing monitor settings such as brightness, color levels, and input source via DDC/CI over I2C, with USB support for certain monitors. It is commonly used for color profile management, saving and restoring monitor color settings around calibration.
Use cases
- adjust monitor brightness from the command line
- switch monitor input source without pressing buttons
- save and restore monitor color settings for calibration workflows
- query monitor capabilities and VCP features
- script monitor settings changes on Linux
- control external monitors on Wayland or X11
When to choose
- you need to control external monitor settings on Linux programmatically or from the shell
- you are building color profile or calibration management software
- you want a stable shared library for display control, e.g. for desktop environments like KDE
When to avoid
- you need to control laptop internal displays, which ddcutil does not support
- you are on Windows or macOS, as ddcutil is Linux-only
- your monitor does not support DDC/CI or MCCS
