OMG, something actually worked!!
however, 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)
edited /boot/cmdline.txt as you suggested, and all seems to be ok

Many Thanks for your help
