Could you help me. I have a Custom Board and a Nano Module. Everything is ok and the Nano is able to display a bright HP display via HDMI. When I switch the HDMI cable to the target screen, Newhaven display a 10.2 "screen of snow. When I reboot the system, the NVIDIA logo appear on the home screen and then Linux starts normally. At boot time, Newhaven display becoming on the snow. Where’s the bug?
