NativeDisplayBrightness

Control your desktop monitor brightness just like on a MacBook!

This a utility application to control monitor brightness with the F1, F2 keys. It utilizes DDC/CI, but this app doesn't have the freezing issues that similar aplications tend to suffer from.

This app also shows the native system UI when changing brightness! It uses the private BezelServices framework for this.

Needless to say, your monitor needs to support DDC/CI for this app to work.
