DisplayBuddy3.9.6

Adjust an external monitor’s brightness, contrast, volume, and input from your Mac with DisplayBuddy, instead of using the monitor’s physical controls. Its menu-bar interface brings multiple displays together so you can manage them from one place. DisplayBuddy communicates over DDC to change real hardware brightness, rather than merely applying a software dimming layer, and supports Dell, LG, Samsung, Xiaomi, and other major monitor brands.

Sync mode links displays so one brightness adjustment affects them all, avoiding manual matching between screens. You can save complete arrangements such as a work setup, movie-night configuration, or gaming setup, then restore each one with a single click. Presets can also activate automatically at sunrise, sunset, a chosen time, when your Mac is charging, or when a particular display is connected.

The utility suits Mac users with several external screens, especially those who regularly change work, entertainment, and evening settings. Most compatible monitors respond through DDC, while an unresponsive display can be handled through automatic gamma control instead. LG webOS and Samsung Tizen smart monitors can receive commands over Wi-Fi, extending control beyond cable-based displays.

DisplayBuddy is freeware for macOS, and version 3.9.6 requires macOS 12 Monterey or later. It supports both Intel-based Macs and Apple silicon systems.
