I've installed the ION EOS Software on a Windows 10 system to start training. When I open in Offline mode (or other) it uses both displays on this system. I would like to turn one of them off so that I can read documentation or watch videos on one screen while working on the other. There's a setting for number of displays that I set to '1' but that doesn't seem to have any impact. And I can't just close a window. Is there a way to limit EOS to one display?
