Searched to no avail, so...


I happen to have an extra iMac (21.5) and thought it would look nice as a second monitor for my 27" iMac... The 27 is ML and the 21.5 is SL.


When I plug the mini display cable in, the 27" is always the "slave" to the 21.5.  Regardless of which is plugged in first.  The 27" never "sees" the 21.5 as a potential second monitor per the display preferences tab.


Any thoughts?

iMac, OS X Mountain Lion (10.8.2)
