The three automated controllers from Neets are two almost similar ones called QueBec II and III (2 and 3).
The last model is called QueBec Pro and is more advanced in its detection on HDMI and VGA.
Common for them all is that they register when a user connects their video source, either VGA or HDMI, and the detection will trigger the device to send a command on RS232 or LAN to start the connected equipment, and when they disconnect it will shut down the system again.
So no interaction required other than connecting the cable!
