What Monitorian is
Monitorian is a Windows desktop utility for adjusting brightness on supported internal and external displays. It gives each supported screen Windows detects its own brightness control, so users can identify displays and change them independently from a compact interface with sliders. The project describes it as a free utility under the MIT License, and its listed plan costs nothing. External display control relies on the screen, its drivers and connection path, and DDC/CI being enabled when necessary. Some adapters, converters, and docking stations may carry video but prevent the control commands Monitorian needs from reaching a display. The project site links to a current master-branch ZIP archive on GitHub; the archive may contain source files rather than a ready-to-run installer. Its download section lists version 4.15.2, last updated July 4, 2026. The FAQ offers checks for monitor detection, DDC/CI, cables, drivers, and connections, along with download-safety guidance. The main interface is for direct brightness adjustments; additional behavior depends on the installed build.
