How to get back the missing monitor option in Mountain Lion's menubar? When plugging in an external monitor on every OS X &lt; 10.8 you could set the monitor options to show up on the menu bar. 

How do I get this option on Mountain Lion?

I connect a DVI monitor via the hdmi ouput on a retina MacBook Pro and I am unable to find a way to enable this option.
Display Menu (free) on the Mac App store adds the menu options back for OS X 10.8
