General public sees these kinds of tiled video displays at best
buy and think this is easy ...
Ability to show and interact with a single application /
visualization across the entire surface
Ability to show and interact with multiple heterogeneous
applications / visualizations on the surface
Treating the wall like a big single desktop using a typical
Running one copy of an application on a master node and
distributing the graphics across all the screens
Running one copy of an application on each node and have them
synchronize with each other
Running a custom desktop manager on each node that synchronize
with each other as middleware
Issue for the tiled display versions - Do you
take the borders into account and hide the imagery 'behind'
them? usually answer is yes, but not always
