    I have a 27" iMac i7 that I would like to hook up an external display to. The problem is, and maybe I just don't understand Macs enough, that I can't find a "video out" port.

    This is what the back of my iMac looks like (the one on the right):

    Audio in, USB, FireWire, Thunderbolt and Ethernet... No mini display port, no mini DVI, no VGA, nothing. I'm reading other forum posts about people doing this, but none mention how they did it! What am I missing?

    the thunderbolt port acts as a mini display port

    So, you're saying that the Thunderbolt PORT accepts a Mini Display PLUG? Well no wonder this is a nightmare to search for. Thanks for your help.

    You are correct. The Thunderbolt port will accept any Mini Displayport plug. Therefore, on a 27" iMac, you can connect not just one, but two displays simultaneously (effectively having 3 monitors), so long as you purchase 2 Mini Displayport adapters.

    For cheaper (but still very high quality) Mini Displayport adapters than what Apple offers, look here. I have dealt with them many times, and they not only ship quickly, but also have great prices and pretty good customer service too.

    it is also daisy chain-able. so you could run more than 3 displays theoretically. im happy to be corrected on that though, i have no experience with more than 2
