I was wondering if anyone else out there has shared in my frustration with M4 model of NanoPi and it's issue displaying through the HDMI port. I have tried multiple distros as well as HDMI displays, I have tested the HDMI cable (all good). The unit is receiving proper power, I am using a 5V 3A wall outlet supply though a USB type C. The microSD is inserted and seated properly (I've also tested with the eMMc flash addon). The M4 powers on, first, both green and red LEDs flash. The red LED stays lit while the green is off and that's it. Nothing else.
