DDC monitor controls (brightness) for Mac OSX command line

ddcctl: DDC monitor controls for the OSX command line

Adjust your external monitors' built-in controls from the OSX shell:

  • brightness
  • contrast

And possibly (if your monitor firmware is well implemented):

  • input source
  • built-in speaker volume
  • on/off/standby
  • rgb colors
  • color presets
  • reset

Install

make install

For an On-Screen Display using OSDisplay.app:
make CCFLAGS=-DOSD clean ddcctl

Usage

Run ddcctl -h for some options.
ddcctl.sh is a script I use to control two PC monitors plugged into my Mac Mini.
You can point Alfred, ControlPlane, or Karabiner at it to quickly switch presets.
