It works.. I didn’t have to disable the IPv6. It turns out that when I had installed the viewer on the ipad, i must not have allowed it access to something. I uninstalled and reinstalled the viewer app this time allowing. It works with the ipad connected via Ethernet adapter/cable to the LAN.
Now the next step is to figure out how to duplicate one of the 3 displays on the PC onto the Ipad display. I presume I must do this on the PC Display controls?
When I duplicate, do the resolution of the PC display have to match the display setting on the Ipad?
I will check if the documentation has guidance on this.
Thanks for your help
