Tom,
  I'm happy to help you get VMD up and running on your tiled display
and to get the best performance your tiled display can achieve. If you
can tell us more about your tiled display system, that would be helpful.
The key question is what software they are using to drive the system,
and next question is how many display tiles your system has, and what
kind of network they are using to drive it. Once I know the answers to
those questions I can give you various suggestions to make good use of it.

Cheers,
  John Stone
