Not sure if this has anything to do with zoom ratio, but can I use the X1 projection calculator (from projectorcentral.com) to gauge the 4805's screen size also? Are the same screen size ranges applicable from a given distance?
This will be my first projector and I have some questions.
I have 11 feet from lens (ceiling mount) to wall (leaving 6" from back of PJ to boxed air return). With a 4805 and these given throw ratios, what will the height, width and drop of my picture be?
My calculations show an image @ 85" diagonal. Is this correct? Could someone confirm? I have plenty of display wall and would like as large a image as practical.
I could mount PJ on the boxed in air return itself, dropping PJ down 10" and as much as 5 feet further back (getting a larger picture), though this puts projector directly over my head in the seating area.
