Using the eDP Port

I want to print out the screen with the DP port at the beginning of JETSON NANO. If you connect the HDMI, the screen is output, but if you connect only the DP port, the screen is not output. What is the reason?

Please provide more information what does that mean.
Have you device been flashed with newer SW? which JetPack?

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

You mean you plugged a DP monitor but there is no output?
