I bought a new ps4 game black border doesn't go away?

Hey guys I recently bought the new piratewarriors 4 for the ps4 and my question to you is I have a black border around the screen now someone knows how to get away I'm desperate

If it is only in the game, then the game has a friction resolution.

Either change the edge in the game settings or maybe it is normal in the game

The answer was unhelpful now

That's not why. Then the picture would still be stretched

Then it would be helpful to tell me whether it's just in the game or not.
