For some really awful reason my second monitor doesn't appear to be displaying anything at all. I entered all of the settings (e.g. span desktop over two monitors, etc.) and there still seems to be no result. What should I do? By the way, if you need to know I'm using the Windows Vista Home Premium operating system, my graphics card is the NVIDIA GeForce 8400M GS (brand-spankin new) and my processor is the Intel Pentium Dual-Core (@ 1.60 GHz each).

Was it displaying anything beofer you installed displayfusion? It sounds as if you are relying on DF to use the monitor.... DF was not built for that. You need to use windows to configure the second monitor for use, then DF is used to control the wallpapers.

I had the entire thing connected and set-up including options and preferences, but it still wouldn't display anything on the second monitor.
