Lens shifting range
This projector is equipped with a lens shift function for adjusting the position of the projected image by using the LENS
SHIFT buttons (
→ page
). The lens can be shifted within the range shown below.
NOTE: 
•  Please do not use the lens shift function when projecting portrait images. Please use it with the lens in the center.
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.

*  The lens shift range is the same for ceiling installation.
(Example) When using to project on a 150" screen
According to the “Table of screen sizes and dimensions” (
→ page
), 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  0.5  ×  79.5"/201.9  cm
≈ 
39.8"/101 cm, downwards approximately 39.8"/101 cm (when the lens is at the center position). Adjustment range in
the horizontal direction: the projected image can be moved to the left 0.15 × 127.2"/323.1 cm
≈ 19.1"/48 cm, to the
right approximately 19.1"/48 cm.
*  Figures differ by several % because the calculation is approximate.
