DisplayBuddy - Control External Monitor Brightness Directly from the Mac Menu Bar

Overview: DisplayBuddy is a macOS-exclusive utility that completely resolves the longstanding issue of Mac users being unable to conveniently adjust external monitor settings via keyboard or system controls. By leveraging the industry-standard DDC/CI protocol, the app enables you to control your external display's settings—just like you would with a built-in MacBook screen—directly from the menu bar, keyboard shortcuts, or even Siri voice commands, eliminating the need to fumble with physical buttons on the back of the monitor.
