From where may I download the earliest Raspbian version that will boot a RPi-4 .
The reason being that I just remembered that when I first got a Pi 4 it booted
( from the image on the downloads page) just fine. No work with config txt needed.
Since then something has changed in the OS that is incompatible with my monitors.
I can configure to make them work, but I want to be able to boot and view off of the
download image. I figure if I work back to an image that works, someone here will
know what change fouled my fun , and perhaps be able to amend the present image
so it will work for me.
