Hello everyone - new to this forum and new to openplotter on pi.
I have a cm4 module on a waveshare minibase A board and I am trying to run both HDMI screens - 1 for a cockpit monitor and 1 at the chart table.
I cannot get the second HDMI - the one with a FFC connector) to work properly. The best I have got is a hazy flickering output on HDMI 2. It will only come up when I replug the hdmi cable, not on boot. I am wondering if this is a hardware problem with the CM4 board. I have changed the waveshare baseboard and it made no difference. I have tested the cables and monitors and it all works fine using a different computer.
Does anyone have any idea where I start to troubleshoot this?
Thank you.
