Full Screen mode displayed on wrong monitor [Solved]

[Xero42]

I run Windows 8.1 with a dual monitor (extended displays) setup attached to a Radeon HD 7870. Normally (100% of all other games I play) when I choose full screen on a game, it is displayed on the monitor that has been set as the primary display. Factorio on the other hand chooses my other display. As a test, I set my secondary display as primary and it still chose that display, which led me to believe that the game engine is favoring the physical display connection on the video card instead of honoring the windows setting. I tested this by physically switching the monitors over, but it is still behaving in exactly the same way. My primary display is at 1920x1080 resolution while the secondary is a little smaller and runs at 1680x1050 which is why it matters to me which screen it is on.

Is there a setting anywhere that can fix this?

P.S.
Out of interest, how does Factorio decide which display to use? From my own experience messing with graphics rendering in Win32 / OpenGL the primary display is always selected by default when creating a full screen window (by passing null as the parent handle) and you'd have to be going out of your way to make it choose anything else. Is it just an idiosyncrasy of the cross platform display handler that is being used?

Yup thanks, I'd just seen this and it works a treat. ( did search before posting btw, but I guess my terms weren't general enough )

I was just coming back to edit my post when I saw that you beat me to it

Thanks again.
