Some PinePhones (my PinePhone Beta Edition for example) have a hardware bug that causes video output to not work. Maybe that's why it isn't working for you. The good news is that one of the devs says he fixed it in software, so maybe we will get this change in our distros soon. You can find more info in this thread (it's one of many): https://forum.pine64.org/showthread.php?tid=14634.
