I was wondering if an iMac could be used as a monitor for a PC. After reading it seems it can only be used as a monitor for another apple product like a macbook pro etc. However after stumbling across this article , http://jsndev.net/199/custom-gaming-pc-build-with-apple-thunderbolt-display-and-discrete-gpu/ , it seems that it could be possible as it can be done with a thunderbolt display. Would anyone with greater knowledge in the matter/ some one who has accomplished it be able to give any advice on this? Any help would be greatly appreciated!
