[QUOTE="chscag, post: 1302902, member: 46727"] It's not a matter of syncing. It still appears that either the adapter is defective or the cable. Universal Access controls your internal monitor; the adapter and cable are supposed to allow the correct signals to be sent to the external monitor. You can see from your experiment that the signals are being reversed. If you change out the adapter and cable and still have the same problem, it's time to take the iMac to your local Apple store and have it checked out. It might be the Thunderbolt port itself that's bad. [/QUOTE]
