The defacto app for controlling monitors

Adjust brightness, change volume, switch inputs

macOS app for controlling monitors, with native support for both Intel and Apple Silicon


Support Server


Lunar changes the hardware brightness of the monitor using the DDC protocol.

It doesn't use a software overlay if the monitor supports DDC/CI.

Installation methods


It doesn't interfere at all with the native adaptive brightness that macOS implements for the built-in display.

It works well along Night Shift and True Tone (and f.lux if Gamma dimming is not used).

Tested and known to work with the following types of connections

  • HDMI (1.0 - 2.1)
  • DisplayPort (1.0 - 2.0)
  • Thunderbolt 4 (USB Type-C)
  • Thunderbolt 3 (USB Type-C)
  • Thunderbolt 2 (mini DisplayPort)
  • VGA
  • DVI
  • Adapters that forward DDC messages properly


I'm pausing contributions for the moment as Lunar has paid features and isn't compilable because of missing parts of the source code (Pro features code is encrypted).


Lunar can't be built from this repo as the source code for the paid features is hidden.
