Hi all. I want to know somebody's opinion on that. My computer sitting behind of my synthesizer because I use it to record some music but I want also use it for things like browsing, banking, movie making and it very inconvenient to work like that. So I think to buy a second monitor and install it 15 - 20 feet away (total lengths of the cables) on another desk, connect it with monitor and USB extension cables and keyboard/mouse. Will I be able easy switch between monitors easily? I wonder how 22" external LCD Monitor going to look like connected to 20" iMac. Will resolution of External Monitor be the same as IMac's?
