I had a 2010 iMac and had 3 monitors connected. One I had connected with a thunderbolt cable>DVI input. the other I had connected through something I bought called displaylink adapter. It worked perfectly.
On new iMac, it works occasionally, but when I restart, the windows aren't in the right place, sometimes I have to recalibrate the monitors using preferences/display ... Any thoughts???
