Could you build this?
Partial The UI wrapper is simple, but reliably controlling third-party external monitor hardware brightness on macOS requires low-level DDC/CI protocol communication and IOKit APIs.
What it would actually take: A native Swift/Objective-C macOS app must interface with macOS DisplayServices and IOKit frameworks, sending I2C/DDC (Display Data Channel Command Interface) packets over HDMI/DisplayPort/USB-C to monitor microcontrollers. The difficult part is dealing with vendor-specific DDC quirks, Apple Silicon hardware limitations, and multi-monitor edge cases where DDC commands are dropped or unsupported without virtual brightness workarounds.
