I have an MB Pro and a Mac Pro. I would like to be able to dock the MB Pro and use the external monitor I have that is currently connected to the Mac Pro. Obviously I don't want to disconnect the DVI cable from the Mac Pro and connect it to the MB Pro every time. I would like a switch that would connect the external monitor to both the Mac Pro and the MB Pro, depending on the setting of the switch. Does anybody have a similar setup? I've tried google but only get results for KVM switches. I just want a monitor switch. Does it exist?
