Looking advice/suggestions on switching between two screens and 2 keyboards on one pc. We have one pc in the fab with a display screen/keyboard and then outside the fab we have a screen and keyboard. We did have a rotary switch kvm thing but its just stopped working. Simple plan would be to replace this but its older than me. Any other ideas or suggestions to switch between the 2 screens without a switching box, don't mind if both screens show the same thing and can be controlled from both sides
