Hi @sethmtraut,
For clarifications, you have five hardwired monitors + two iPads (spacedesk) as monitors. two of the five monitors are touchscreen capable, is that right?
„will only recognize one at a time as a touch screen“
-could you try connecting iPad #1 together with the two touchscreens if the touchscreen is working? then disconnect and try iPad #2 if it is also working.
– in case one of them is not working, please try checking the input settings of the iOS viewer if the touch screen is enabled. just go to the gear icon below -> Input devices
„When I go to tablet PC settings and try to tell it which ones are touch screens it faults out before getting to all monitors“
-During the Tablet PC Settings, does it close when it’s time for the iPad monitor? Could you please try going through the iPad screen first?
-Also, could you try excluding some monitors, or even the other two touchscreens before doing the Tablet PC Settings?
– rebooting your iPads may also help
