Does anyone know a programmatic way of dimming secondary monitors while keeping the primary display screen fully bright? I have investigated some existing software, but most will only dim all monitors (or only the primary one). I feel like this might be a windows registry modification perhaps. (This would be for the Windows 7 platform) Even if someone could point me towards registry entries that can be modified for screen brightness levels. I think this is handled in the OS and not always in the monitor itself.
Any and all help is greatly appreciated!

Use the SetMonitorBrightness API.
