    I am about to order a ceiling mount but need help to work out the length of the mount.I have a 92"draper motorised screen,approx 14'lounge,2.4m ceiling height,where should the viewing area start in relation to ceiling?what is the optimum length for the mount to be?

    Thanks in advance

    Well the general opinion seems to be the the image will be 4" (ish) BELOW the lens centreline if the projector is the right way up.

    To be totally honest if I were you. The only way to get it 100% correct would be to create a temporary platform, even wood and a step ladder, or something to do a dummy test, even if it's not 100% correct you can then get your tape measure out and see how much it's wrong by and go from there....

    I used the calculation charts but would not use them as gospel really.

    This is where lens shift is invaluable. I approximated the length of the mount, added a few inches for leeway, then lens shifted the image up till it was perfect. :) I also didn't need to get the lateral positioning perfect when sticking the mount on the ceiling. A lot of people underestimate lens shift till they try to mount the pj.

    It might be better for you to error on the short side a few mm as you can lengthen the mount by using slightly longer screws with longer spacers.

    Trail and error with step ladder , good idea
    dont drill till your sure , maesure twice drill once as they say
    this all helped with my AE100
    mounted on wall on TV bracket
    easy to do as i lay machine upside down as its flat
    but 200 has curved top i think , so not as easy !!
