HDMI Loop Out

There is not any hardware loop-out circuit on Pi-Cast. However, Pi-Cast features both of the two HDMI ports of CM4, allowing you to achieve HDMI loop-out functionality through software means.

If you are using the pre-build images for Pi-Cast, the loop-out service is already installed. All you need to do is just enable and start it. You can follow the below commands to enable the loop-out service.

  1. Enable the loop-out service.
    systemctl enale kvmd-hdmi-loop-out
  2. Start the service
    systemctl start kvmd-hdmi-loop-out
