Are you trying to do a videowall? That technique above is used on a
lot of high end scan converters. Some have RGB input and depending on
the brand/model have up to 4 wide and 4 high RGB outs (tres tres
dispendieux, mon ami). Cheaper would be to use 2x PCI express cards
with dual out.

You could also use non standard resolutions, depending if you are
driving analog or lcd screen or even projector (digital need to be
driven at native resolution for a decent image quality).

 BTW, the logical next step is a 360 setup. Like Disney use(d) at
Epcot center, or at Expo 86 (Vancouver) and before that Expo 67
(Montreal). But all of these were using film cameras and film
projectors (would be pretty easy to do this with computers and
projectors).
