If you do keep the projector, you should try projecting 2 movies at once on the same wall...maybe there will be some demonic result to start an internet rumor about.
this is a common technique to make projector screens in stadiums etc brighter... no demons so far.
and in regard to the rest of what you posted... whatever
i seriously don't understand the attitude "I'm a customer so you have to treat me like royalty, kiss the ground I walk on and suck my cock while you're at it"

I think one of the main things to consider here should be how many projectorless walls you have in your house. If it's more than one, giverrrrrrrrrrrrrrrrrrrrrrrrrrrrrr .
