Displaying HDMI sources on Apple Vision Pro

While it's possible to stream most content to Apple Vision Pro directly over the internet, having the ability to use Apple Vision Pro as an HDMI display can still be useful.

Since Apple Vision Pro does not support connecting to an HDMI input directly or using an HDMI capture card, we have to be a little creative to make this work. NDI provides the ability to stream HDMI content over a local network with really low latency, and it works great with Apple Vision Pro.

This page shows the setup I’m using.

  func isEqual<T: Equatable>(lhs: T, rhs: Any) -> Bool {
    guard let rhs = rhs as? T else { return false }
    return lhs == rhs
  }
  
  return isEqual(lhs: lhs, rhs: rhs)
}
