Unable to rotate dislay desktop on that configuration. Have tryied for 2 days and I’m tired !!!
Have installed according to what is explained in https://github.com/pimoroni/hyperpixel4
All is OK except that the desktop is diplayed in portait mode.
Impossible to rotate in landscape, Did Pimoroni bot have any driver simple to install ? I am not a programmer and ahouold avoid to compile a c programm !
Any help is welcome


There are a couple of threads on the go with that same issue. I don’t think anybody has found a solution yet.
Maybe Phil @gadgetoid can help sort it out.
