Lunar - control your monitors, even on M1
Intelligent adaptive brightness for your external display
Note: Lunar changes the actual (physical) brightness and contrast of the monitor.
It doesn't use a software overlay.
Table of Contents
- 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 Exception list if you need more brightness for specific activities (watching movies, design work)
- Individual settings per display
- Manual controls and hotkeys for setting brightness and contrast that respect the min/max values per monitor
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/Software controls are not used).
Tested and known to work with the following types of connections
- HDMI (1.0 - 2.1)
- DisplayPort (1.0 - 2.0)
- Thunderbolt 3 (USB Type-C)
- Thunderbolt 2 (mini DisplayPort)
- Adapters that forward DDC messages properly
Check the FAQ
- Lunar usually doesn't work with monitors connected through USB hubs/docks/adapters because a lot of them don't forward DDC messages properly
- Sync mode doesn't work when the Macbook lid is closed because the light sensor is completely covered
I'm pausing contributions for the moment as Lunar has paid features and isn't compilable because of missing parts of the source code.
Lunar can't be built from this repo yet as the source code for the paid features is hidden. I will try to post stubs for those paid features to at least make it compilable in an only-free-features form.
