Display setting not retaining in windows 10

Question

Hi,

Our System runs Windows 10 IOT (LTSC 1809) 64 bit. It has the configurations–

Integrated system (all-in-one) configuration with an integrated display and 2 display ports.
The display ports are labelled OuterPort and InnerPort. We require that

any display connected to InnerPort should extend the display.
any display connected to OuterPort should clone the display.
We configure the displays to match the above requirement using windows display setting screen. When displays are connected to both the ports, the system works as intended.

Problem: When a display is connected to just one of the ports, it always acts as if the display is connected to OuterPort i.e Clone. Even if we configure the display as required, it reverts back to this erroneous behaviour once we restart the system or unplug the display and plug it back.
