Beginners • Re: Screen not showing on boot.

assuming you are running bookworm.
(dont know about PI1, oldest i have is PI4)

you can set the resolution manually:
in /boot/cmdline.txt (add to the front/end of the line, NOT a new line)
-- IMPORTANT NOTE: for Bookworm, the file is at /boot/firmware/cmdline.txt !!
video=HDMI-A-1:1024x768@60D
(or whatever resolution you want)

Note: the current KMS video driver ignores Config.txt, setting a mode there will have no effect.
you must set it in cmdline.txt
