Launch the game. Minimize the game. Go to Windows screen resolution settings - Display and change the monitor screen resolution settings there. Close the game and restart. It should help. This helped me set up windowed mode 1290x720 on an old 1280x1024 monitor.
sorry for asking on an old post but ive tried everything i can to fix this on mac since im using whiskey to run this game and it seems like you might be able to help
