You should be aware that when they say a 1920x1080 resolution is recommended, they mean the game basically doesn't work at other resolutions. At other resolutions, various parts of the interface will be off the screen and inaccessible, which makes various game features inaccessible entirely. Different resolutions make different things inaccessible. While the game can be windowed, it fills the full monitor space, so you can't just run it in a 1920x1080 window on a larger monitor, either.
