Finally managed to complete the setup of 3 monitors on my desktop along with an SVGA output to a 42″ plasma screen. Using 3 Dell 24 LCD Monitors – 2407WFPb.
The setup is on a PC and uses 2 video cards. I combined a GeForce 6200 256MB PCI card along with a GeForce 6800 XTreme 256MB PCIe to get the 4 display output. Will do a detailed post for those curious to see how a setup like this can work.
