tried to boot in to safe mode but it still got stuck at the black screen.
Since you can do that you could use Command mode to investigate what your symptom means. E.g. if it is a driver crashing it may show up in the logs. But you may be lucky and find that it is only showing you the second screen of an extended display in which
case you would try changing that, e.g. press Win-P, CursorUp, Enter (as if you could see the Second Screen dialog come up and use it that way <w>).
Good luck
