I am new to the Home Theater world. However, I am diving in head first. I am currently finishing my basement. I need a lot of advice. Here is what I do know. I have purchased the Sanyo PLV-Z2 projector. My seating will be about 16 feet away from my screen. My screen will be mounted to the wall. I want a screen that is approx 100 inches wide. How far away from the screen should I mount the projector? How do I calculate the exact dimensions of the screen I need? What brand screen would you recommend? Any suggestions from those who have been through the process would be appreciated. Thanks.
