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 21). The lens can be shifted within the range shown below.
NOTE:
• Please do not use the lens shift function when projecting portrait images.
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.

(Example) When using to project on a 150" screen
According to the “Table of screen sizes and dimensions” (→ page 74), H = 130.7"/331.9 cm, V = 73.6"/187.0 cm.
Adjustment range in the vertical direction: the projected image can be moved upwards 0.5 × 73.6"/187.0 cm ≈ 36.8"/93.5

(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 × 130.7"/331.9 cm ≈
19.6"/49.8 cm, to the right approximately 0.15 × 130.7"/331.9 cm ≈ 19.6"/49.8 cm.
