ClickMonitorDDC vs m1ddc

ClickMonitorDDC is a free Windows utility for controlling external monitor settings through DDC/CI. Depending on monitor support, it can adjust brightness, contrast, speaker volume, RGB gains, and color temperature. Multiple displays can be controlled independently or have settings synchronized. Controls include tray options, hotkeys, and the mouse wheel; shortcuts switch profiles, while command-line arguments or hotkeys can automate adjustments and profile changes. The listed Windows versions are 7, 8, 10, and 11, and the monitor must have DDC/CI enabled. Some laptop displays may restrict DDC/CI, and some monitors may not support every setting. The download is a portable app that runs without formal installation. The privacy policy says the software runs locally and does not collect, transmit, or store personal data from the computer, monitor, or hardware configuration. It separately says the website may collect browsing data and use cookies. The utility is described as intended for professionals, gamers, and everyday users who want monitor controls.

m1ddc is a free command-line tool for controlling external displays from Apple Silicon Macs. Through DDC/CI, it can set or read luminance, contrast, RGB gain, volume, mute, and input source when a display supports those controls. Supported connections include USB-C, DisplayPort Alt Mode, and compatible built-in HDMI ports. Certain Dell displays also expose PIP, PBP, and KVM configuration. The command-line interface is intended for scripts, and the project links to a Hammerspoon example. A Raycast Display Input Switcher extension is also linked, although it does not cover every m1ddc feature. The tool is available for macOS on Apple Silicon and does not support Intel Macs. Building requires clang from Apple’s Command Line Tools; the README says those tools install automatically if absent. The repository includes an MIT License. Display behavior depends on the connected monitor’s supported controls.
