If you got a new monitor for your Mac, you noticed there's no way to control its brightness from the Mac.

Lunar brings back brightness control for monitors, along with volume, contrast, input switching and can even turn off monitors or the built-in display.

Dim the brightness of monitors, wireless displays, iPad Sidecar and AirPlay displays using simple sliders in your menu bar.

Lunar Lite is the lite version of Lunar, an app for controlling every aspect of your external monitors (https://lunar.fyi)
