Lens shifting range
This projector is equipped with a lens shift function (→ page 23) for adjusting the image position
using dials. Lens shifting is possible within the range shown below.
NOTE:
• In case lens shifted volume exceeds the below illustrated range, blur and shade may appear around ends of projected image.
Legend: V “Vertical” refers to the screen height and H “Horizontal” refers to the screen width. The
lens shift range is expressed as a ratio of height and width, respectively.
Lens shifting range:
Vertical direction: +60%, −0%
Horizontal direction: ±29%

(Example) When using to project on a 150" screen
According to the “Table of screen sizes and dimensions” (→ page 126), H = 127.2"/323.1 cm, V =
79.5"/201.9 cm.
Adjustment range in the vertical direction: the projected image can be moved upwards 0.60 ×
79.5"/201.9 cm ≈ 47.7"/121 cm (when the lens is at the center position).
Adjustment range in the horizontal direction: the projected image can be moved to the left 0.29 ×
127.2"/323.1 cm ≈ 36.9"/94 cm, to the right approximately 36.9"/94 cm.
* Figures dier by several % because the calculation is approximate.
