Lunar

The defacto app for controlling monitors. Intelligent adaptive brightness for your internal and external monitors.

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.

Features

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).
