I have a Dell PC and a 22" monitor with dual inputs (digital and the other) and I am going to get a Mac shortly. I have dithered a bit but think - well, today at least - it's likely to be an iMac. I would be using Logic mainly. I'd quite like to continue to run the PC for WP, spreadsheets, stuff like that. I don't really have enough desk space to have two monitors. So, can I run the monitor output of the PC into an iMac? Would I need a KVM switch? Do I, indeed, make any sense whatsoever?
