iMac as an exxternal display for MBP?

Yes, but only with the 27" iMacs. Your MBP also has to have a mini display port output. Though I'm sure you can get an adapter if you have an older with DVI.

OK. Good to know. So how does this work? What connects to what?
 
I was actually considering this as well. You do know that your iMac needs to be on, even though you're only using it as a monitor by-pass, right? Seemed like an awful waste. I just ended up getting a 24" ACD.

I am the OP. Here is what I needed: something to connect my older 20" Apple ADC Cinema Display to newer tech. Here is what I got: a MacMini because it has BOTH a mini-DVI and a mini-DisplayPort. With the proper connectors, it works perfectly!

Thanks to all for their suggestions.
 
Quite a bit different solution from what you were initially looking at, but the most important thing is that you found something you're happy with.

Yes. I realized that I just wanted to get a couple more years' usage out of that display. It has pretty good resolution (1650 x 1050) so I hated to get rid of it.
 
And this will ONLY work with the 27"?

I ask because I'm about to get a MBP and wanted to dual-screen with my 24" 2009 imac. Will this not work? :confused:

I don't believe you can do this with a 24" iMac. It was only the latest models (21.5" and 27") that can function as monitors for another computer.

As far as I know the feature is only available on the 27" models introduced in October, NOT the 21.5". Just more incentive to upgrade to the more expensive model.
