I don’t know of any KVM switch that broadcasts to 2 computers at the same time. I’m sure something like that now exists but not many are going the hardware route these days. I don’t blame them.

Take a look at my hardware guide here. It may help you understand what Vectras are all about. I'd go the software route and save the cash. I started the exact same way your boxing now, using 2 keyboards and mice.
