RPi4 on Bookworm not working #3

How do you get this to work on the latest Bookworm? The config.txt doesn't seem to work. Thanks.

HI, please refer to: https://github.com/eleclab-rpi/Display_Firmw! are Guide: ElecLab Display Firmware Update Guide.pdf Firmware: HDMI_0736_1280x400_RPI5_Bookworm.hex

Bookworm does not need to configure config.txt and cmdline.txt, because it will automatically detect HDMI EDID and then output HDMI signals with specified timing. Best wishes!

Actually just figured it out for Raspberry Pi 4. Thanks

sudo nano /boot/firmware/cmdline.txt Add video=HDMI-A-1:1280x400M@60D

Mark it, great, you could use dmesg to check the hdmi edid information.

I am having same issues. I do not see any edid detection, and config and cmdline did nothing. Screen defaults to 1

hyperlocal@pi0:~ $ xrandr --verbose | grep -I edid

hyperlocal@pi0:~ $ dmesg | grep -I edid

hyperlocal@pi0:~ $ cat /etc/os-release
