Can I connect more than one external monitor with only one thunderbolt port? Mid-2011 iMac 21.5 inch
CPU: Intel(R) Core(TM) i7-2600S CPU @ 2.80GHz
RAM: 8.00 GB

Right now, I connect an external monitor to my iMac using the one thunderbolt port that I have. Is it possible to connect a second external monitor? If so, how?
thunderbolt dock will do it.  get one that adds dvi, hdmi or passthrough thunderbolt.

my caldigit does hdmi + passthrough thunderbolt so i can get 2 displays on there.
