I searched the web wide and far, under Windows there doesn't seem to be a way to control the brightness of a standard DisplayPort desktop monitor from software, even after installing the monitor drivers. My keyboard has brightness keys, the brightness slider pops up and moves, but the screen brightness stays the same.

Did you enable C2I in the monitor settings?
