How to use Surface hub with multiple displays

I just dealt with a similar issue with the Surface Hub 3 50inch at the university I work at.  I needed to duplicate the screen of the surface hub to a separate display capture card to create documentation but as you may already know, you cannot natively alter how the displays are presented on the surface hub.

My trick was to locate the skype folder under Task Scheduler when in the admin account of the device.  From there you will want to create a scheduled task copying the address for powershell from the logon task that is initiated by the skype user logging in.  Then you will want to set the parameters to:

displayswitch.exe /clone

And make sure you set the task to be run by the Skype user, otherwise this trick won't work.

Additionally, you'll need to set a 1 minute delay to the task after logon to ensure that the task launches after the teams room launcher has done its changes to the system config.

After that, every time you login to the skype user on the Surface Hub 3, the displays will automatically go into duplicate mode after 1 minute allowing for your meeting contents to be projected to multiple displays within the meeting room.

This might not be precisely what you are looking for, and being able to expand the work space of the teams room to multiple other devices would be greatly appreciated, but this is a small win.
