Control your external display brightness using the keyboard keys you already have. No software overlay. True hardware-level brightness control.
Features
Brightness Control does one thing and does it exceptionally well — hardware-level brightness control for external displays.
Press F1 and F2 — the brightness keys already on your keyboard — and your external display responds immediately. No extra shortcuts to memorize, everything works as expected.
Communicates directly with your monitor hardware via the DDC/CI protocol — the same method used by professional color calibration tools. The backlight truly dims, color accuracy is fully preserved. No Gamma overlay, no dark filter.
Summon it anytime with a single click. A clean popup panel provides independent sliders for each display. No Dock space taken, no unnecessary windows.
Dual or triple monitor setup? Brightness Control detects all external displays and supports individual adjustment for each one.
Brightness changes are animated at 60fps with a custom easing curve. Every adjustment feels smooth and natural, never abrupt.
Enable "Launch at Login" and forget about it. Every time your Mac starts, Brightness Control is already running in the background.
