Frustration reaching critical mass 5 monitor set up!

Have been trying now for a while to get my 5 monitor set up to work. Running 2x Nvidea 780 cards, a Matrox Triple Head to Go digital edition, but I cannot for the life of me get the two 19" monitors to work no matter what I do..... Have the 3head2go on the first card, and 3 Acer monitors set up on it - this works fine....the two 19" (where I am planning on displaying cockpit instruments) on mated to the second card in the DVI slots (leaving a vacant DVI slot on card one for a touch screen overhead I am waiting on plus the HDMI outputs where I am debating another touchscreen for pedestal/ radios.

Tried SLI, no joy... 3d nothing... Disactivate SLI... Nichts......Tried activate all displays.... They come up green, but when you apply settings... NADA .... Had to walk out this afternoon for fear of taking a ball bat to the whole kit!!! Any help appreciated..

Can send screen shots and a pic of my set up to anyone who thinks they can help me sort the gremlins out!!
