@Edward M, Ed Greshko: It's completely generic, the projector doesn't have
a brand, doesn't has a model.
My computer it's a laptop with VGA port, the only cables I have are the
ones I show in the following images:

http://bit.ly/HrV0KV
http://bit.ly/Hs3qS1

(Same as above)

So, Quick idea: As the USB port is not capable to stream video, I was
wondering if
with this cable:

http://bit.ly/I9GS7K

Maybe it will be possible to connect the projector to the VGA port of the
PC and then select
it as an output instead of the laptop screen resulting that in a projection
from the computer
to the projector?? O.o, In a "Diagram" My idea is:

This to the projector: (As it only has AV IN port exactly for this cable):

http://bit.ly/HrV0KV

Then This to that cable:

http://bit.ly/I9GS7K

And Finally the VGA end from that last cable to the VGA port of the Laptop,
then maybe run the
command issued above:

"xrandr --output VGA"

And as far as I understand it should result in projection from the laptop
computer to
the projector as it were a VGA monitor right??

What do you think? :)
