Could you build this?
Partial A clean desktop wrapper is easy to vibe code, but reliably controlling multi-monitor brightness across diverse hardware vendors requires low-level DDC/CI protocol communication and driver workarounds.
What it would actually take: The app requires low-level C++/Rust or C# integration with the Windows Monitor Configuration API (Dxva2.dll) and raw DDC/CI I2C bus communication. The hard engineering challenges include vendor-specific quirk handling, faulty EDID parsers, slow I2C bus latency, and managing monitors attached via DisplayPort/HDMI converters or docks where DDC/CI packets frequently drop. A competent systems programmer experienced with Windows desktop hardware APIs is needed to ensure compatibility across disparate monitor manufacturers.
