Multiple tablets mirroring a third tablet

I have need for a small system that can connect 3 identical android tablets with 1 being a “master” and 2 others mirroring the first. I want to use them for a band application that has the music on the first tablet using a hands free foot pedal to change the sheet music and the other 2 to mirror the first. This will allow 3 people to be on the same page. Can the USB7-HUB7-81x be a charging hub along with sending video to multiple monitors??


No, our hub cannot do this.
