After purchasing a home theater projector, unless it is a portable projector and a portable screen, it is necessary to mount the projector and screen so that the picture can be properly transposed onto the theater projector screen. Hopefully, by this point in time, the relevant factors for setting up a home theater system have been well planned but that is not always the case. Maybe the home theater was received as a gift, or maybe a spouse or friend purchased the projector without considering how it was going to be used.
