Where I work we each have to computers. Each computer has its own monitor, but we would like to split the keyboard and mouse between them. We currently just use regular KVM's to do the job, but we need to switch to usb so they are buying new ones. My question is, Do they make a "KVM" that doesnt use a key combo to switch machines. What we want is almost like a dual monitor setup, where we can just move our mouse off the right side of the screen and it switch to the other machine automatically?
