I just tried some other resolutions because the graphics where still very wrong(I was getting extra blur on higher resolutions except 4k etc.) , it was just that last thing I did before I quit that version of the game.
You seem to be having a different issue then, and the settings I messed around with wouldn't matter.
When you have the black screen you could try just going in/out of full screen mode with Alt+Enter to see if something happens (more than the black box being full-screen or smaller/windowed).
