Hi,can anybody explain the following ground pi behaviour. The ground pi is running on Pi3B+. I flashed the latest OpenHD release 2.0.8 Buster, connected an official Raspberry PI 7" LCD screen and everything worked fine. Then I disconnected the screen and connected goggles over HDMI and in the first boot it also worked.
Then I switched back to LCD screen and have got no image, just black screen. The same black screen over HDMI.
When I use PI4 as Ground PI I can switch between LCD screen and HDMI without any problem.
What is wrong with using PI3B+ on OpenHD ???
