Tried to setup a dual-screen eyefinity virtual screen for coop, and while it is working, the aspect ratio and resolution is all wrong even in borderless window mode.
Instead of using 7680x2160 the game seems to use just 3840x2160p and stretches the picture to fit the two screens.
I would assume that setting 32:9 aspect ratio would fix that issue or being able to set the correct display resolution, but no luck with that as there is nothing in the menu. I am only getting offered 16:9 and a few other less wide aspect ratios, but not 32:9

Is there a way to fix that? Either some ini files to manually set the resolution or force 32:9? Or do I need to prepare my eyefinity setup in a special way for the game to recognize it? Anyone has the game running like that?
