I have old raspi 3 for a year and just start raspi 4.
Now I am running my server on raspi 3. I want to move my server to raspi 4.
I just insert my microSD card of raspi 3 into raspi 4.
But it shows only black screen.
by the way, raspi 4 works on new raspbian buster. but I have to set it up as server from scratch.
my very basic questions:
1 does raspbian stretch run on raspi 4?
2 what wrong and how to fix black screen trouble when raspbian stretch boots on raspi 4?
please give me some hints on this.
