macOS app for controlling monitors, with native support for both Intel and Apple Silicon
Community
DDC/CI
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
Features
- Native keyboard control and hotkeys for setting brightness, volume and contrast that respect the min/max values per monitor
- 1000-to-1600 nits of brightness for supported XDR and HDR displays
- Dim brightness below 0% for late-night work
- Sensor-based Adaptive Brightness (and contrast) based on an external light sensor
- Sync-based Adaptive Brightness (and contrast) based on the built-in light sensor of the MacBook or iMac
- Location-based Adaptive Brightness (and contrast) based on the sunrise/sunset times in your location
- App Presets if you need more/less brightness for specific activities (watching movies, design work)
- Input switching from a convenient dropdown or using up to 3 input-specific hotkeys
- Screen orientation change from the menu bar or using hotkeys (Ctrl+0/9/8/7 mapped to 0°/90°/180°/270° for the display with the cursor on it)
- Hidden resolutions accessible from a dropdown in the Display Settings menu
- BlackOut: turn off monitors (or the built-in display) selectively while also keeping important functions:
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).
