I now have it staying in 1080P mode when switching by these steps:
1. configure the display to 1080P
2. In the Advanced setting referred to in the link above,  create a profile
for the display.
3. Turn On the 2 connecting display options.

When I switch away from the PC to another HDMI input it is working now. But
I'll switch away again and go get more coffee and see what it does when I
come back
