Is there a easy cheap way of making a dual monitor setup with my eMac & PC? Please note I only want my eMac to be a dual monitor setup. I could careless about the PC. (PC is only there for the wifes accounting crap) From what I know the dual setup wont work when the PC is up and running, only when the mac is turned on I want a dual setup. I just need to know what kind of cables I need and how to set it up. Hope someone out there has some answers for me.
