The ANX7688 IC inside the phone converts the A64's HDMI output to AltDP, which goes through the Type-C port and out of the phone, and the AltDP-to-HDMI bridge chip inside the official dock converts AltDP back to HDMI. This entire path is pretty much invisible to the A64 SoC or the software running on the PinePhone.
Also, the official PinePhone dock should be fully functional even with no charger connected to the dock. It would take quite a lot of power from the phone if you use the dock's HDMI port, so connecting a charger to the dock is highly recommended.
Any chance that the PP/bridge would require HDMI2?
My TV screen is HDMI1. When I connect the PP to it, it displays a message: " Searching for signal ..." and then about 5 sec later "No signal found." I can easily connect my laptop to it via HDMI (also running bullseye). I realize there are likely many hardware and software differences between the two devices. For example, I'm using the PP bridge with the PP, but the laptop has a built-in HDMI output.
