At the moment getting the hdmi to work is very hit and miss. So keep plugging away. I can't give you any hints because I haven't found any pattern yet.
I wrote a long detailed post but the format keeps getting messed up. So, here is a trimmed short version.

This post provided me information on being able to use both the Pinephone screen and external screen at the same time. Assumed hardware fix and anx firmware has been flashed. Install wlr-randr. Connect dock, cables, keyboard, etc.

Have Pinephone screen on, then "wlr-randr --output HDMI-A-1 --on", "wlr-randr --output HDMI-A-1 --mode 1280x720@50Hz". If there are noticeable graphical issues restart Phosh "sudo systemctl restart phosh.service", then set the external resolution again ""wlr-randr --output HDMI-A-1 --mode 1280x720@50Hz".
