• 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.

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 differ by several % because the calculation is approximate.
