Windows Brightness Helper

@eisland/windows-brightness-helper · v26.0.1

Screen brightness monitoring and control via .NET console EXE (spawnSync/spawn). Supports built-in displays via WMI and external monitors via DDC/CI.

Important

Setting brightness on external monitors requires DDC/CI support. If the monitor does not support DDC/CI, setBrightness will silently fail for that display.
