The Host PC runs a real time operating system that can only support output to a single display device. For desktop Host PCs this would typically be a monitor connected by a VGA or HDMI cable. For laptop Host PCs the display would be the laptop screen. If you want to mirror the Host PC screen please use one of the approaches outlined below:

Desktop Host PCs
  • Use a splitter device / cable (either HDMI or VGA) and relevant cables to both monitors. These devices are inexpensive and readily available.

Laptop Host PCs
  • Laptop Host PCs can either output video to the laptop screen or a monitor connected via HDMI. It is not possible to have both simultaneously.
  • Depending on the laptop Host PC model, simply connecting a monitor via HDMI may be sufficient prior to booting the laptop. If not, shutting the laptop lid during startup will force the HDMI output (but you will need to attach an external keyboard and mouse).
  • If you want the Host PC software to appear on two monitors, use a splitter cable to divide the HDMI out, as above.
