I don't have the biggest monitor but it is large, there are certain resolutions that will actually fit your monitor (hopefully) my normal resolutions that I use are 3840x2160, 2048x1152, 1920x1080. You might be able to switch to a different resolution that could fit your screen, but the game defaulted me to 2048x1536 and I can't change the resolution because the screen fitting won't let me click the apply button, if I try to click the apply button it clicks out of the game. Just wish their was a way to change the resolution without clicking the apply button, maybe the Enter key.
