The document discusses and compares long throw and short throw projectors. A long throw projector is suitable for projecting images over larger distances but results in a less defined image further away, while a short throw projector creates less space between the projector and projection and is used when a compact setup is needed. It also notes that a Matrox device can be used to split one image across multiple projectors, allowing each projector to display a different portion of the overall image or video.

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. The Matrox
can also play multiple
images or videos at the
same time.
 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.
