DA, thank you. I just like to help and have the resources to do some of the testing needed.
Quote: "maximise on two monitors at once(not mirrored)"
I have three computers with dual monitors (I like a lot of real estate to open editors, browsers, and lots of stuff at one time).
Unless you plan your graphics for working in a dual width type space like that, a full screen spanning two monitors might not look or play right.
And, I for one, really don't want any one program taking up both of my monitors like that. It is sort of one of the reasons I have multiple monitors.
