Simultaneously stream the same image from the GOPRO

I need to simultaneously stream the same image from the Go-Pro to 2 separate devices at the same time (devices meaning 2 different tablets of any kind) and or small light weight computer monitors with HDMI Input obviously. Has anyone ever done or tried doing something similar? I also subjected to the Go-Pro bc of quality and size. This meaning I am trying my hardest to make this project as mobile as possible. I apologize for the crazy question:)
