There is plenty of off-the-shelf equipment for video walls.  The
medium is becoming quite popular with multi-image presentation firms.
The pricing and reliability are becoming quite competitive with the
multi-projector slide shows which have been a staple for conventions,
museums, etc.  (Although I still prefer the much better image you can
quite with slides.)
