So my wife has recently lavished me with a 2nd 24 inch wide screen 1080p monitor...for which I am utterly grateful. Now I am trying to make the most of it. I'm looking for a free software tool that will allow me to stretch desktop wallpaper and manage my dual setup.

I see Display Fusion is pretty popular, but it's not entirely free and I'd have to go pro. Does anyone have an alternative that is reliable? Is the non-pro version sufficient or should I really go pro?

2nd question...What are you all currently doing with your dual setup? I'm currently running wow and games in full screen windowed and browsing on the other monitor. Is it even feasible to stretch the display across in a 2 monitor setup?

Just looking for tips of the trade really.
