Has anyone used SoftTH v2 with Unity?

I am trying to set up a multi-screen display with Unity, spanning over 4 desktops. (2x2 - 3840 X 2400) SoftTH seems to be the logical option, but I am not sure how to get it to work with a Unity application to maximize the output over all 4 screens. Could anyone shed some light on the matter or explain how to do it?

Simply copying the dll file into the complied root seems to work after all. I was trying to use the 64bit instead of the 32bit driver.

I hope this helps someone.
