Jetson Nano is stuct at Nvidia icon then I lost the display at all when nano is connected to m2key converter(it is plugged to the m2key port) with a PCI video capture card. I use same setup on Jetson TX2 and it works fine. M2 key part is working because I tried it with a wifi module.
By the way Nvidia icon appears with low resolution. I used both power options power jack and micro USB with MaxN power mode. It does not work.
Thanks for your helps.
