Yes, that is the correct setup for the this system (we have the Vizwall ourselves). > My question is more about the graphics card > required for that, do we need any special card for that?

You need an Nvidia Quadro or ATI FireGL card that has the QUAD_BUFFER support and has also the special mini DIN 3-pin synchronization connector. The cable from that goes into the xpo boxes, without the sync you will not get stable stereo. The consumer cards (GeForce/Radeon) do not support neither the QUAD_BUFFER mode nor have the required hardware for the synchronization. Regards, Jan
