Good morning all! I recently got one of the new late 2013 27" iMacs. Anyway, occasionally I use this computer as an external monitor for my MacBook Air. Works great, yay me. (thunderbolt to thunderbolt) The question is... If I had a PC with video card that had a display port, could I use an adapter to mini display port, and then connect it to my iMac via a thunderbolt cable? I love how sharp and crisp this display is, and if I had a decent PC kicking around and I could use the iMac screen that would be great. Otherwise I need to make room for another monitor on this desk. Thanks again!
