    I've got a 27" iMac (Late 2009). I'm building a PC (blasphemous, I know) for gaming and I want to use my iMac's video input functionality, mainly because it's a great display, I want to keep using my iMac for everyday computing (email, web browsing, etc), and it will be a pretty elegant solution.

    My question is, though, can I just use an Apple Mini-DP to DVI adapter to go in reverse, IE: from the DVI output of the PC's video card into the Mini-DP input on the iMac? There are active DVI or HDMI to Mini-DisplayPort boxes, but I'm curious if that's really necessary (they seem geared towards home-theater type use cases and do things like put the audio onto the cable or get the audio out of the cable)

    Pretty sure you can't run those adapters backwards succesfully for what you're trying to do.

    If you're building a new PC, can you just get a card with displayport output? Then a $5 DP -> miniDP cable will do the trick.
