This is an old Neewer display (around 2017) connected to a RPi 4B+ 4Gb ram with a fresh install of Bookworm 64bits on 64Gb Micro SD card.
From bootloader it hasn't EDID info.
Steps I performed after first time boot:ThenAdded at the end of the line: video=HDMI-A-1:1280x720M@60D
Reboot -> No signal
What else do you suggest to try?
Thank you
