Hi - I'm in process of mounting my projector screen an realized I'm about .75-1" off center in my room (room is 15Wx17L); this drives me nuts since it was preventable. My screen is a Stewart 133" cine-w.
At any rate - I have my projector mounted essentially dead center on the other side of the room @ 14'2" therow (which will probably be more like 14" now that the screen is mounted on the wall).
I also have a Schneider 1.33x M lens that will be installed. However, I've read that horizontal shift should be more/less avoided when using lenses as they exacerbate these geometry issues (not sure if this is specific to prism vs cylindrical lenses or not...).
So I forseeably will need to shift my image accordingly (horizontally) about 1" (maybe 1.5" to account for some fluff). Do you guys see this as insignificant when paired with my lens? Or do you think I should bite the bullet and reposition everything (by shifting over both mounts .5")?
