[Paraview] About Tiled Display

[Nancy]

Hi,all,

Our lab will buy a SGI machine with three graphic pipeline and build a display wall(1x3) for large scale visualization.
We have test the tiled display function of paraview on three PCs, and we find that there is no overlap region between
the three images on those three PCs' displays. 

But,the technical engineer of display wall told us that there needs overlap image region between the three projecting region
to smoothing the color and shape of every two neighbour displays.

Who can tell me whether this is a problem when we use paraview on our new display wall in the future?
And what should we do for it?

Thanks

Nancy
