Similar to current Keyboard-Video-Mouse (KVM) switches, this invention has multiple machines plugged into a device with a single keyboard, mouse, and monitor handling IO functions. The difference is that this device would allow multiple monitor outputs to be seen as "Picture-in-Picture" windows on the monitor.

Switching among machines via "hotkeys" would only switch the keyboard and mouse inputs. The video output would be visible for all machines at all times. This will be achieved via software in the device acting as a display manager that combines video outputs from the connected machines into a single video feed to the monitor. This software would listen for input change requests (ie: alt-right-click in a machine's PiP window), and would change the keyboard and mouse inputs to that requested machine. This would eliminate any network requirements or the need for resident software on the attached machines.

This approach is advantageous because it allows an operator to view the output of all connected machines while maintaining keyboard and mouse focus on one machine.
