1. Enable Device Tree Overlays
You need to enable both the HDMI and LVDS overlays. On TorizonCore or Toradex Reference Images, do this by editing the overlays.txt file on the /boot partition:
# Backup the current overlays.txt (optional)
cp /boot/overlays.txt ~/overlays_backup.txt
# Add overlays for HDMI and LVDS
echo "fdt_overlays=verdin-imx8mp_hdmi_overlay.dtbo verdin-imx8mp_lvds_overlay.dtbo" > /boot/overlays.txt
sync
reboot
