David, will the F4V3 have the same 680 pixels per port, or have you been able to increase.

Help me with the Differential Expansion units. Starting with a F4V3 and a Differential Expansion, and then add (2) 4-String Differential Receiver Board netting a 4-4-4 port arrangement what would be a typical pixel assignment? Assuming 680 is still the limit, then 340 - 170 -170 would be one option yes? Is 680 still the limit?

What about this: (still assuming 680 pixel per port)

Port # - - - base board . . . . 1st expansion . . . . 2nd expansion

1 . . . . . . . 100. . . . . . . . . . 500 . . . . . . . . . . .100
