I have a Mac Pro (2008 eight core 2.8 GHz), a MacBook Air (mid-2011 Core i5 1.7 GHz), and a 30" Apple cinema display (maximum resolution 2560x1600). I have a mini displayport to dual-link DVI adapter for the MacBook Air.
I want to set up the cinema display with a 2-port DVI KVM that fully supports both of these machines, ideally with ports for both DVI and USB.
What are the technical requirements I need to know about to ensure full compatibility with my hardware? Is it possible that some DVI KVM products would not support the maximum resolution of my cinema display?
