<< what the difference between a kvm and a cheapie keyboard /monitor / mouse switch? I have seen the cheapies from 18 -24 dollars while kvm cost 100+ >>
A powered kvm switch like this will allow higher resolutions/picture quality on the monitor, and keep your mouse and keyboard working on both. The cheap switchboxes will lose your mouse on some computers. If you unplug your mouse and plug it back in, and it doesn't work anymore, you would need the more expensive type.
