I picked up the new iMac a few months back, a generous 27-inch one that sits proudly on my desk. However, with the upcoming release of Battlefield 4, I've decided to buy myself a PC too that will be used solely for gaming. My question is, quite simply - can I use my iMac as a monitor using any sort of wire? I'm not bothered about having to buy something, I just need to know whether or not I need to splash out on a second monitor to go on my desk. I appreciate there has been some discussion around this topic before, but having seen this: http://www.youtube.com/watch?v=6C3YjHGhm_I - I'm starting to think there may be hope. Apparently he used a Mini Display Port to Mini Display Port wire, from his graphics card on the PC to the back of the iMac - is this true? Cheers!
