Well the problem is that i have 2k screen (so pretty big), but you haven't enabled fullscreen button and setted viewport dimensions too small. Look in your project edit page. Search for "Viewport dimensions" and "Frame options". It's an easy fix
You're welcome. An by the way. I recommend setting in godot settings in: "project settings -> display -> window -> stretch mode" from disabled to canvas items. This will stretch or squish camera, so it will show the same content on any resolution.
