The vertical offset is the offset in which the image is projected from the lens. The 4805 has a 27.8% offset. This means the image is projected at 27.8% of the height of the image from the lens. For example, a 92″ diagonal image will have a width of 80″ and a 45″ width. 27.8 x 45 = 12.51″ offset So in a table mount situation, the bottom of the image will be 12.51″ from the center of the lens.
