Hey there Hash461,
Although we wish screen casting was an official feature on Oculus Go, your Oculus Go does not officially have the ability to screen cast to a TV. However, your Oculus Go device does have some other great features that you have access to, such as built in audio, and an ergonomic design!
Even though your Oculus Go might not officially support screen casting, Oculus Quest and Quest 2 do have the casting feature! You can learn more about casting using Oculus Quest or Quest 2 on the pages below:
