Ok, so if my screen is 84" wide, then at 2.35:1 my height will be about 35.75". This then becomes the height for all picture formats, correct? In this case that means my 16:9 will be 63.5" wide at that height. SO, what ever projector I purchase in the future must be able to do 63.5"x35.75" (16:9) at what ever distance the projector is mounted from the screen.

Currently I have the cables run at about 14 to 14.5 feet back from the screen (this is not yet cast in stone). Seating distance is planned for about about 10.5' back.

If I plan on the Z4, provided I read the Projector Central info correctly, my projector should be mounted at 14.8' from the screen. Is that correct?
