Use keyboard and screen

The first HDMI is close to the USB-C connector.

If it boots up into a black screen, then it might be an issue with Extended Display Identification Data (EDID) of the monitor and video driver.

If so, add the video mode to /boot/cmdline.txt

console=serial0,115200 console=tty1 \
root=PARTUUID=37c8e4ff-02 rootfstype=ext4 \
video=HDMI-A-1:1920x1080@60D rootwait


/boot/config.txt uncomment hdmi_safe=1 if no booting text appears.
