• XDR Extended Brightness — Unlocks brightness above the standard system maximum (100%) on MacBook Pro Liquid Retina XDR and Pro Display XDR displays. A red zone appears on the slider when in the extended range. Enable via an opt-in warning dialog the first time you reach maximum brightness.
• XDR Safety Controls — "Reset to Standard Brightness" and "Disable XDR Extended Brightness" menu items let you quickly return to normal range.
• Brightness sync respects XDR range — When syncing brightness across displays, the target display's maximum (including XDR) is respected.

• Control your display's brightness, volume and contrast!
• Shows native OSD for brightness and volume.
• Supports multiple protocols to adjust brightness: DDC for external displays (brightness, contrast, volume), native Apple protocol for Apple and built-in displays, Gamma table control for software dimming, shade control for AirPlay, Sidecar and Display Link devices and other virtual screens.
• Supports smooth brightness transitions.
• Seamlessly combined hardware and software dimming extends dimming beyond the minimum brightness available on your display.
• Synchronize brightness from built-in and Apple screens - replicate Ambient light sensor and touch bar induced changes to a non-Apple external display!
• Sync up all your displays using a single slider or keyboard shortcuts.
• Allows dimming to full black.
• Support for custom keyboard shortcuts as well as standard brightness and media keys on Apple keyboards.
• Dozens of customization options.
• Simple, unobtrusive UI.
