I have 3 Dell 21" Widescreen monitors and 2 Nvidia GeForce 8800 GTS 512 video cards(SLI disabled)
Vista Ultimate 32-bit
All 3 monitors work properly and I have had this set up many times I just finally decided I wanted one big image across all three screens instead of the same image repeated.
I would like to span a single image across all 3 screens.
Tried using the background option in Vista but it would just put the same image on each screen not span across all 3.
In the following links are 2 ways to do this but the desktopfusion cost money and has very large memory usage issues on vista at least that is what I have found.
and the other way says to use the background utility in vista and select the titled option in the background utility which failed to work and do what I wanted.
Also the instructions are only for 2 monitors not 3
