My primary machine would be my laptop (win10)( < 1920x1080). I would have three more machines(desktop extension, 1920x1080), each a Fire TV. Two of the TVs would display the exact same thing(mirror) and the third would display something else. The primary machine would also display something else. The three TVs would display Chrome tabs/windows in fullscreen mode. My primary machine would display a chrome browser as well. So three browser tabs/windows in all, across four machines, two of which are duplicated removed link Is this possible? I'm not exactly sure how to get two of the machines to mirror each other.
