What does Lunar do?
Lunar is a macOS application that gives you precise control over your external monitors. Instead of relying on clunky monitor buttons or software overlays that degrade image quality, Lunar uses DDC (Display Data Channel) to send commands directly to your display hardware. This means you can adjust real brightness, change volume levels, and switch inputs like HDMI or DisplayPort—all from your Mac keyboard. It works with most modern monitors and offers special native integration for Apple displays like the Studio Display and Pro Display XDR.
The app stands out by offering multiple control modes. Manual Mode lets you use your standard Mac brightness and volume keys for external displays. Sync Mode automatically matches your external monitor's brightness to your MacBook's built-in display. For specialized needs, it offers XDR Brightness to unlock full display potential on high-end Apple hardware, Sub-zero Dimming for working in dark environments, and Sensor Mode that uses an external light sensor for automatic adjustments. There's even a FaceLight feature that turns your monitor into a video call lighting panel.
Lunar is perfect for Mac users with multi-monitor setups, especially developers, designers, and professionals who work long hours. It helps reduce eye strain by maintaining proper brightness levels throughout the day and enables focus by letting you black out distracting screens. The free version covers basic DDC control, while the Pro version ($23 lifetime) adds advanced features like automatic sync, XDR brightness, and ambient light adaptation.
