Could you build this?
No Controlling volume on external HDMI/DisplayPort displays requires low-level DDC/CI hardware protocol communication over macOS I/O Kit and CoreDisplay private APIs, which involves deep hardware and reverse-engineered OS driver programming.
What it would actually take: Built with Swift/Objective-C interacting directly with macOS `IOKit` and undocumented DisplayServices APIs to send I2C DDC/CI commands to the display's micro-controller. The main challenge is hardware compatibility across diverse monitors, USB-C/HDMI dongles, Apple Silicon display controllers, and managing non-standard vendor implementations of VESA DDC/CI specs.
