Well, what happens to your HDMI output in general when you power your netPI? I mean independent of the container ... from the beginning. I want to make sure that your HDMI port is working in general. Because netPI is printing out some logging messages on HDMI during boot sequence.
You need also to make sure that the HDMI port is connected to netPI from the beginning. Also most important is not to use any adapters like DVI to HDMI converters. netPI graphic CPU is only able to detect an HDMI output monitor and its signals. This is done during the first 1-2 seconds after power on. If no monitor was detected during this time, the HDMI output will remain black to whole rest of the time until you reset netPI.
Then you said you have used the docker container "HDMI output". What is the status of this container when you use the Docker Web UI. Also each container started writes some loging information into an internal log file ... which you can make visible in the Docker Web UI icons that you can click on the "container overview" list. What does the container log output say?
Thx
