1) I have the Diamond BVU 195 installed.
2) I have two Samsung Syncmaster 2443BW monitors.
3) Both are set up as DVI monitors.
4) The Macbook Pro sees one monitor connected through the Diamond BVU.
5) The MacBook Pro does not see the monitor that is plugged into the built-in external display port.
6) Systems preferences see two monitors and the laptop screen, but does not allow for making changes.
7) Is the problem because Diamond (Displaylink software) is not for 64 bit snow leopard?
8) Is the problem because both external monitors are the same make and model?
9) Is the problem because both external monitors are DVI?

Any help would be appreciated.
