Will not use Rasppberry different models- I have 3 Pi zeros that all work with the display. I have a Pi3a+ and no matter where I place the display for it it does not display at all. I've tried every position.

Before filing a bug report

Replicate your issue on Raspbian Lite Raspbian Lite is the preferred target OS for this system. I will not address bugs that can only be replicated on 'nix with a graphical user interface.

Ensure your operating system is up-to-date ...and that you can replicate the problem with an up-to-date (and rebooted) system. To ensure all is update, run the following in a terminal, sudo apt-get update && sudo apt-get dist-upgrade -y && sudo apt-get auto-remove -y && sudo apt-get autoclean

If you do the above two things and can still replicate the issue, then...

FWIW, I've run this system on RPis from a B+, several model 2s, many, many model 3Bs, 3B+s, and at least one model 4. Never any display issues. I would toy with omxplayer interactively to figure out display parameters. They all start at 0x0, FWIW.
