DisplayBuddy vs Lunar

DisplayBuddy controls supported external monitor settings from a Mac menu bar or Windows taskbar. Depending on the display, it can adjust brightness, contrast, speaker volume, input source, resolution, and rotation. The Mac app uses DDC for hardware control and can use gamma dimming when a monitor does not respond. The maker says it also controls supported LG webOS and Samsung Tizen smart monitors over Wi-Fi. Users can save presets and synchronize brightness across displays. On Mac, presets can be scheduled by sunrise, sunset, time of day, charger state, or connected display; the app also supports Shortcuts, Siri, a command-line interface, and MCP. The Windows app supports Windows 10 and 11, with presets, hotkeys, input switching, and resolution and refresh-rate controls. Personal costs $24.99, paid once for one Mac, Pro costs $29.99, paid once for up to two Macs, and Family costs $49.99, paid once for up to five Macs; each includes lifetime access. There is no free plan, but a 7-day trial is available. Core controls work offline after internet-based license activation.

Lunar is a macOS app for controlling monitors, including external monitor brightness, volume and input. On compatible monitors it uses DDC to send brightness and input commands directly. Manual Mode provides hotkeys for external-monitor adjustments, while Sync Mode copies the MacBook’s adaptive brightness changes to external displays. Sensor Mode adjusts brightness and contrast using an external ambient light sensor; Location Mode responds to the sun’s position. Clock Mode schedules changes by time or by sunrise, noon or sunset. Pro features include XDR Brightness, sub-zero dimming, Auto BlackOut, BlackOut and FaceLight. Lunar also works with macOS Shortcuts and includes a command-line interface for monitor automation. It supports macOS 11 and later and runs natively on Apple Silicon and Intel. When DDC is unavailable, Gamma can dim a display but cannot change its volume or input. The free version permits 100 Manual Mode adjustments and 100 Shortcuts action calls per day. Lunar Pro costs $23.00 USD as a lifetime license.
