Hi Paul

What is the 'eVigilant' products???

You can do this with 2 servers and 6 HD outputs... Just frame lock them together...

But 1920x1080 may not be the best resolution to use in this scenario... You may need more of a 4:3 ratio for this work... ?

Curved work Is always difficult to get right especially at the top - since the image can be highly 'squashed' depending how far up you blend.
blending a top 7th projector is almost impossible
(anyone else do comment...)

Since you mentioned a 7 th projector - I assume this would point vertically up?
Cant you just use a wide angle fx lense on a single projector (like the puffers sphere) to do the entire job?
Just a thought
