I have a new X1 Carbon Lenovo that I would like to connect to my iMac as external monitor to get a bigger monitor. I understand that if I don't have a laptop with thunderbolt port it won't be possible vi a thunderbolt to thunderbolt connection. The Lenovo has a miniDP port only. My question: is there any other way to use my iMac as external monitor for the Lenovo? MiniDP to thunderbolt converter, Ethernet connection, wifi,...there must be a way, right? Thanks, A Dillock
