Hi, I've googled for quite some time but couldn't really find an answer to this question all information seemed to refer using an imac as a mbp etc. monitor. Now my situation: I have an iMac 27" and a mbp but I also got a quite good acer pc catching dust under my desk. Now the thing is I would love to use my iMac as an monitor for that acer pc. Is this possible (With special hardware, software etc.)?
