Is there a command line option to make it run on a specified monitor?

The one the game is picking isn't my center one. There doesn't seem to be an option to choose it in settings.

Hey rrusell,

Unfortunately, there is not an option in the game to change that. The game starts on the PC main monitor. I know that it is not ideal but currently the only way to change the monitor is to put the one you want as the main one from Windows settings.
