iPhone users can use AirPlay for wireless screen mirroring, and Android users can use Google Cast or built-in screen mirroring. Just enable the feature in the projector's settings for first-time setup.
Make sure the projector is powered on and the Roku account has been successfully activated.
The phone and projector must be connected to the same Wi-Fi network. (Note: Same network is required for wireless casting.)
On the projector home screen, go to: “System” > “Screen mirroring” > “Screen mirroring mode”.
Select “Prompt” mode.
