If you are using a Magewell HDMI capture card, setting it to be black when no video feed will allow HDMI share to automatically turn on when a live HDMI video feed is plugged in, and automatically turn off when unplugged.  For example: walk into a meeting room with a laptop, plug in the laptop HDMI cable, and HDMI Share will automatically pop up.
