I am throwing content, why is it not mirroring?

Make sure that you are throwing in the right direction. You need to throw the content in a specific direction as each direction (left/right/up) are different displays
Check Reactiv SUITE settings and make sure that the secondary displays are correctly configured
Make sure that the object you are throwing is properly hitting the border of the screen and bounces back into position. If the object doesn’t properly hit the border of the screen it will not mirror
