How to Stream Your Mirrored Screen to a Live Platform

 

In professional or advanced production scenarios, built-in streaming tools may not fully support multi-source input, complex scene composition, precise control, or custom output formats.


For cases such as gaming streams, product launches, sports events, multi-location sessions, education, or interviews, you can use 3uAirPlayer to mirror and stream your screen directly to a live platform.

 

Step 1: Mirror your iOS device

 

On your iPhone or iPad, open Control Center, tap Screen Mirroring, and select your computer from the device list.


Once your device screen appears on the computer, the mirroring setup is complete.

Click Start Streaming to begin transmitting your mirrored screen to the live room.
