I run 3x27" monitors at 5760 x 1080, the game tries to launch, but ends up minimized and I can't maximize it or run it any size, I guess it doesn't like the large screen.

Can I force it in Window mode so I can play it ?

otherwise it was a waste of a purchase.

I have not been able to test this kind of setting but the unity engine I am using support that. Take a look at this thread:
http://forum.unity3d.com/threads/127117 ... igurations

I am sure it may run full screen somehow, but I don't want it to run full screen, I am trying to get it to run windowed...

I am able to do so, but it has it's quirks.

Once I launch the game, it is minimized. Then I can press Alt-Enter and it pops up windowed on a single monitor. I can then adjust the Windowed size.

So far so good

but any time I have to click the option to go to the main menu... it resets the video, and I presume tries to go to full screen, and thus ends up minimized again. So I press Alt-Enter to get it back windowed on one monitor again. But it's back to 1980 x 1025 on that monitor, so I have to resize it again etc.

pain, but it works.

This recurrent problem when entering the main menu seems to be happening because the game consider you are in full screen mode and try to set it every time like when loading for the first time. Fortunately this issue is easy to solve, we will include it in a patch to be published shortly (next week I guess)

I will also try to keep the current resolution set in a text file that overrides the initial maximised start if present.

Yes

I was looking for an INI or other text file that might hold the screen parameters so I could manually set them for Windowed and then set the resolution for the window and/or location of the window.
