DisplayBuddy 3.9.4 for Mac
DisplayBuddy 3.9.4 MacOS
Menu-bar sliders and presets that talk to external monitors over DDC/CI so F1/F2 and software controls adjust hardware brightness instead of only dimming the Mac GPU.
Click the menu-bar item and each connected display gets its own brightness, contrast, and volume strip when the panel supports it. Sync mode ties sliders together so a 27-inch desk monitor and a MacBook screen move in step. Presets store the full stack brightness, contrast, volume, input source, resolution, rotation, HDR, True Tone, Night Shift, and multi-display arrangement and recall it in one click. Schedules attach presets to sunrise, sunset, clock times, charger state, dark mode, or display connect events so a docked work layout can apply before you touch a button. Desktop widgets and Control Center entries can fire the same presets without opening the main window.
