Monitor Brightness Control review
A free Linux utility for DDC/CI monitor control with GUI, CLI, profiles, and hotkeys.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Monitor Brightness Control is an open-source Linux utility for adjusting brightness and contrast on compatible external monitors through DDC/CI. It is aimed at Linux desktop users who want more control than display hardware buttons provide, with both a PyQt graphical interface and a command-line interface. System-tray integration, global hotkeys, monitor detection, multi-monitor control, saved profiles, and presets support different desktop workflows. It supports common distributions including Ubuntu, Debian, Fedora, Arch, Manjaro, and openSUSE.
Its strongest area is control flexibility. Users can work from the GUI, CLI, tray, or global hotkeys, while saved monitor profiles and Day, Night, and Gaming presets provide reusable configurations. Multi-monitor detection and control make it suitable for desks with more than one compatible display. The background service extends its utility beyond one-off adjustments, although the project requires compatible monitors, I2C communication, and the ddcutil utility before these controls can work.
Monitor Brightness Control is a focused choice rather than a complete monitor-management suite. The current feature set covers brightness, contrast, profiles, presets, and control interfaces, but does not include input switching, scheduling, or automatic brightness. Users who want free, open-source control of compatible external monitors on Linux should find its scope appropriate. Those who need time-based changes, ambient-light integration, input selection, or broader platform support should choose a product designed around those capabilities instead.
