Official LineageOS 20 FP4

Hello, I am using lineageos 20 on my fairphone 4 and I’m very happy with it.
But I bought the Fairphone 4, because of the HDMI USB C port.
Now I bought the ViewSonic TD1655 portable display with touch.
When I connect my phone with the monitor, the touch function is rotated 90°. So when I swipe left to right, it swipes top to bottom.
If I choose desktop mode in developer options it works fine. However, I think the standard environment is perfect for me. maybe that can be changed?

Thank you for your help
