In their own words
DDCcontrol
DDCcontrol is free Linux software for changing monitor brightness, contrast, color levels and other settings through DDC/CI. It offers a GTK interface for graphical control and a command-line tool for terminals, scripts and automation. Communication uses Linux’s i2c-dev interface and /dev/i2c-* devices, which must be readable and writable before monitors can be configured. USB-connected DDC/CI displays are not supported yet. A monitor database is required for monitor-specific controls and proper operation. The ddccontrol-scanmonitor utility reads a connected display’s EDID, capabilities and supported controls, and can generate a monitor database XML file; scanning does not alter control values. The maker’s database index lists 474 monitor profiles in release 20260928. Packages are listed for Debian/Ubuntu, Fedora and openSUSE, alongside source releases and source builds. The project uses the GNU General Public License version 2.0 and directs support questions to GitHub Issues.
Twinkle Tray
Twinkle Tray is a Windows utility for managing brightness on multiple monitors from a system-tray icon. Sliders can adjust one display or all displays at once, and the app can control DDC/CI monitor features such as contrast, volume, and power state. It supports most laptops and DDC/CI-enabled monitors, using WMI for internal laptop displays and DDC/CI for external displays. Users can schedule brightness adjustments by time of day or when the computer is idle, and bind hotkeys to particular displays or all of them. Command-line arguments support custom scripting, and the application is localized in over 20 languages. Twinkle Tray is free and can be obtained through the Microsoft Store or as a GitHub installer. Compatibility may be limited with VGA or DVI connections and some USB, Thunderbolt, or Surface docks using HDMI or DisplayPort. Its privacy policy describes collection of settings, operating system, CPU name, app version, user interactions, and estimated location through Google Analytics; users can opt out in Settings.
