The solution is:

Start -> Control Panel -> Hardware and Sound -> Device Manager.

In the Device Manager window, look for “Monitors”, then right-click your monitor and select “Uninstall”. Be sure to also check the “Remove driver” option. Once removed, click the “Scan for hardware changes” icon.

Voila. “Adjust plan brightness” returns, mystery solved.
