Currently, I connect my Drive Orin target device with a monitor DP cable and I tried to use the openwfd_nvsci_sample, but i got the error of initializing the OpenWFD immediately.

$ ./openwfd_nvsci_sample --sample 1 --display 0 --mode 1920x1080@60

Dear @rlu1 ,
Could you share syslog. Also,Could you check disconnecting monitor and use VNC and test application if it works?
