ExternalDisplayBrightness is a small utility which allows you to change the brightness of external displays connected to your Mac using keyboard shortcuts, just as you would change the brightness of the built-in display on a Macbook. By default the application takes over the default brightness keys on a Mac keyboard, which are mapped to F14 and F15, respectively. When pressing the keyboard shortcut in combination with Option + Shift, the brightness changes in smaller increments, just like on a real Mac.
