Hello,
This is not something I have heard about before.
Monitor layout and resolutions is stored centrally by Windows based on all monitor serial numbers connected at a particular time regardless of what they are connected through.
May be the display persistence keys in Windows are corrupted.
Would you please try the following instructions to force monitor rediscovery?

You will have to set it when you reconnect the displays after deleting the registry keys, but, if that works, it should be the last time.
Kind regards,
Alban
