I need some help over here. I have two Mac Pros, 2009/2010 3.46 5,1 machines. But I only have one monitor. Before I got a new monitor a couple of months ago I used an IOGear KVM switcher. Cheap. Worked great. But the new monitor, Samsung, uses DisplayPort/HDMI. I can't use that because it used DVI. So I got two adaptors - mini-DisplayPort to DisplayPort. But I need a new switcher. I need to share the monitor and keyboard/USB. Any ideas? I don't need 4 ports, just two.
