I can only play FM20 using my laptop(gtx1050) using a small screen. If I start in fullscreen (either using commands like -fullscreen -no_exclusive_fullscreen, or with the game option), change to fullscreen or change or maximise the window the screen goes black. Alt-enter back to the small screen works and allows me to play again.
Curious thing is that when I plug a second screen in to my laptop the game does start fullscreen on the other monitor.
Anyone have an idea what I can do to get this to work?
