Brisync

Synchronize your external display brightness with built-in display.

How it works

Application reads current brightness of your built-in display and passes it to external displays via DDC interface.

You can adjust brightness by a menu in the system status bar or hotkeys:

  • brightness down: ⇧ + ⌃ + F1,
  • brightness up: ⇧ + ⌃ + F2.

Adjusting brightness in the menu changes internal brightness factor for this display so future brightness updates match your preferences.
