Can someone explain this part of the review, in English:
"However, if you wish to ceiling mount, you can shift the lens such that, once the projector is inverted, the top edge of the image is below the centerline by about 25% of the picture height. So for example, if you are projecting a 120" diagonal image, the picture height will be 59", and the maximum gap between the top of the image and the centerline will be 14.25". In practical terms, after adding a few inches for the ceiling mount itself, if you have an 8 foot ceiling, the 120" image will appear on the wall about where you want it. If you are going for a smaller image, say 100" diagonal, or if you have a much higher ceiling, the range of the lens shift will not be able to compensate for such a radical offset. In these cases, you may wish to use an extension tube with the mount to keep the image from appearing too high on the wall."
I'm looking to ceiling mount a projector where the ceiling is 7' 8". I am going with a minimum of a 110 inch (diag) screen and a maximum of possibly 118 inch (diag) screen (1.78 -- HDTV screen format).
So where will the bottom of my screen be (in relation to the floor) with this projector? Will I need a long pole for the ceiling mount or what?
And where exactly is "where you want it" -- when the review says "... the 120" image will appear on the wall about where you want it."
Where do YOU want it?
