The document discusses and compares short throw and long throw projectors. It notes that short throw projectors are used to create less space between the projector and projection, while long throw projectors can project images to further distances, such as in a theater to cover a larger space. It also mentions that a Matrox allows one image to be projected by three separate projectors so each projector can be assigned different aspects of the image.

3. If I needed to create
less space between a
projector and the
projection, I would
use a short throw
projector over a long
throw projector. This
is because a long
throw projector could
be used for further
distances, and a short
throw projector could
do the job of creating
less space between a
projection and the
projector.
4. If in a theatre I
needed a projector in
a rig to cover a larger
space I would use a
long throw projector
over a short throw
projector. This is
because a short
throw projector
wouldn’t cover the
area and wouldn’t
throw the image far
enough, whereas a
long throw projector
would.
6. A matrox allows 1
image to be
projected by 3
separate projectors.
Each projector can be
assigned to different
things so each
projector/output
device aren’t the
same.
1 matrox has 2
outputs.
More than one
matrox can be used.
