Looking for help as this has got me stumped and Apple technical didn't offer much help over the telephone.
I am trying to connect external display to my iMac 21.5-inch, Mid 2011 2.7GHz Intel Core i5 using MDP (male) to HDMI (male) cable without any luck, I just get the no signal message even upon trying a few different monitors/TVs.
Can't be a faulty cable as I also have a MacBook Pro 13", Early 2011 2.3 GHz Intel Core i5 which works fine with external displays using this same cable and any of the monitors I have tried.
Both iMac and MacBook are running Mountain Lion 10.8.2
Apple offered very little help over the telephone just advising me to take this to a repair centre not the most convenient thing as this is about an hour away!
Any help would be greatly appreciated.
