i am using the left monitor as my main and that's where the game runs.
The black screen happens when I try to exit the game or when I disable the full-screen mode in-game (1920x1080 resolution - native).
If I run it in windowed mode it's fine.
The weird thing is that it doesn't always happen when I disable the fullscreen mode ether.
I don't have a good explanation for it. I am using an nvidia card with latest drivers but I don't use the surround mode.
Not sure if it helps but I use HDMI for my left and right monitor and the middle one uses an VGA cable.
I will do some further testing today but it's painful to restart the pc everytime it happens.
Is there something like a log that gets created or a way to enable it?
