DFR0698 - 12.5" 4K IPS Touch Display with LattePanda 3 Delta

Hi there,
i wanna use the Lattepanda 3 Delta only wired by one usb-c cable to the monitor.
i use the usb-c cables delivered with the monitor but it only delivers power to the
lattepanda. the only way to get a picture on the screen is to use the mini-hdmi-to-hdmi cable.
there are pictures on the product page that say it shall work.
i have searched the bios but there are no options to change the video output.
anybody has succes with this setup?
