How to use Brightness Keys on External Displays in macOS Catalina



In this video we cover MonitorControl, a handy utility for Macs that lets you control any display’s brightness using the regular brightness keys on Mac keyboards.

In order to work, your display should support DDC. Most modern monitors do.

This is a crazy setup – I put four additional monitors up to test different displays with this utility. Some are older office displays and don’t work, but most should be fine.
