I'm about to get my first projector and the 1070 is on the top of my list. I have a bit of a problem though, as I would like to place the projector on a shelf on a wall facing the screen. The room is about 3600mm deep, and if I understood correctly the throw on this is only 1.5, which would mean that the minimum width for the screen is 3600mm/1.5=2,4m. Thats way too big. I'm looking for about 84" screen so the maximum width would be somewhere in the 1850mm range.
Other option is to put it on a ceiling mount and bring it closer to the sceen. I used BenQs throwing distance calculator ( http://www.benq.com/microsite/projector/throwratiocalculator/
, btw, it shows no lens shift for the W1070 here?) to see how it would bit. Can some of you guys help me a bit. If I choose the following settings: ceiling/wall mount, set the distance from the screen to a 2.8 meters and set the diagonal screen size to 85", projector (not screen) distance from the ceiling to 0,35 meters (I don't want it hanging too low) and ceiling height to 2.5 meters. Now it seems to work.
Problem is though, that now the projected image (or screen) is way too high, at 1,05 meters from the floor. I would like the low end of the image to be somewhere at 0.6-0.8 meters from the floor. How much I can lower it with the lens shift on the W1070?
