Dual port video card help needed

[Ops]

I have a client that has a machine with a dual port video card.  The
"display names" (as shown in the properties/configuration window of the
video card) are \\\display\u1 and \\\display\u2.  My app needs 2 stacks, a
"control" stack and a "display" stack.  I would like to have the "control"
stack display on the \\\display\u1 monitor and the "display" stack display
on \\\display\u2.  Anyone ever accomplish this or know how I can accomplish
this task?  THANKS!!
