I'm going to keep this short and sweet, I don't want to waste any one's time. I have a 2010 Mid-iMac (has miniDisplayPort port) and I just got a Mid-2011 MBA (has Thunderbolt port), and I just reached confusion . If you check out this video, you can obviously tell, that if my iMac was thunderbolt, I would be able to use it as a monitor. But since it's mDP, I cannot. Is there anyway I can connect my Macbook Air into the iMac, being able to use the iMac as a monitor? If so, what wire do I need, to connect the two? Thanks.
