How do I get rid of the black void and zoom in on my game?

Hi, I'm having an issue I never had before. I started a new project and when I preview the layout/game the game is zoomed out and there are black borders surrounding my game. How do I fix this?

Maybe you set something in the properties bar so that the game runs in a certain display mode? Go to your layout > click anywhere > Left pane > Project properties > click View. There in the Display section you can fiddle with the different display modes, and check if there's anything out of the ordinary.

You've likely selected "Letterbox integer" scale mode in project properties. Change it to "Letterbox scale"
