I have Dell U3818DW hooked to my Radeon 7970 via mDP and was missing the ability to control brightness. After mucking with ddcctl, OSDisplay and bash scripts that i wanted to feed unto Karabiner I found it had all been packaged already!
This thing does multiple monitors, brightness, contract, and audio volume. Audio will need Lilu discussed elsewhere.
