In case your game also doesn’t launch on the main screen you can try setting the monitor to a different position on the virtual canvas:

Sunshine is a open source alternative for the popular Nvidia GameStream Moonlight. It allows you to stream your desktop from one device to another in your local network e.g. your smartphone or TV.
