Know your gear
The Singlewire InformaCast Fusion hardware appliance (IPTA-IFS) has two HDMI and one DisplayPort video output port. When power is applied to any of these, the other two are disabled. After turning on, you cannot change the video output port. If you want to change the port, connect a cable to the desired port and restart the hardware appliance. If no cables are connected to any of the three video output ports, the HDMI port above the DisplayPort port becomes active by default.
