I tested my display with a RPI 3B, 3B+ and a Zero W. All of them had the same issue. Btw i used this display the last years for testing the Raspberry Pi. After that i connected the RPI 3B to my TV screen and it works with the patch applied. > > I will try more hardware combinations tomorrow to see, this issue is > more board or display related. > > Best regards > Stefan > >
