Hi Guys,

My iMac is the 2011 model BEFORE March 7th where the new iMac came. So my iMac does NOT have a Thunderbolt port.

Now i'm sitting here with my new Apple Display 27" ThunderBolt Screen, trying to connect it with my iMac, but nothing happends. I tried to set the ThunberBolt plug into the displayport on my iMac (It's the same type cable) .. But nothing is happening?

Isn't there a way to make my display work on my iMac. Is that ThunderBolt really that important?

Under Requirements from the Apple Thunderbolt page:
Thunderbolt-enabled Mac computer, including MacBook Air, MacBook Pro, Mac mini, and iMac
Sorry, you're outta luck :(

EDIT- What's said two posts above is a little misleading. TB is backwards compatible with MDP, in the sense that a TB cable can carry a MDP video signal. But unfortunately, MDP isn't forwards compatible with TB, in the sense that an MDP cable can provide a signal to a TB display. That would be a little more accurate, I think.

EDIT EDIT- That's also a little confusing. Basically, an MDP-only Mac can only work with an ACD. A TB Mac can also work with an ACD. A TBD will only work with a TB Mac. A TBD will not work with an MDP-only Mac.
