I need to connect 3 (maybe 4th in the future) monitors to one pc. Monitors should display 3 applications, each application on different monitor. Applications are displaying cameras from video surveillance (remotely). These applications have a FullScreen mode, so in this setup each application should go fullscreen on its monitor, not the others. Basically I need 3 separate desktops.
I know of 3 solutions to achieve multi-monitor environment, but I don't know if they will work in my situation. I will sort them per price, from cheapest one:
1) 2 graphic cards
How good solution is this one? Should there be any difficulties during setup (other than usual ones)? Which models would you suggest? Ati or NVidia?
2) USB monitors
I read that models like Asus VW223B can connect up to 6 monitors, using EzLink application, but I am not sure how well this application will handle what I need (mentioned at the beginning of post)?
3) video card with 3/4 monitor outputs, like some Matrox models (hard to find and pretty expensive).
The price between 1st and 2nd option is not big, and if Asus monitors and EzLink can provide what I need, I would probably go with this solution, because of the easy expansion in the future. I need some acknowledgment that someone has done this, or seen it done.
