Lens Shifting Range - NEC PH1202HL User Manual

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 22). 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 calculation) If projecting on a 300 inch screen using an NP-9LS13ZM1 lens unit
According to the "Table of screen sizes and dimensions" (→ page 157), H = 261.5"/664.1 cm, V = 147.1"/373.6 cm.
Adjustment range in the vertical direction: the projected image can be moved upwards 0.5 × 147.1"/373.6 cm ≈
73.6"/187 cm, downwards approximately 73.6"/187 cm (when the lens is at the center position). Adjustment range in
the horizontal direction: the projected image can be moved to the left 0.11 × 261.5"/664.1 cm ≈ 28.7"/73 cm, to the
right approximately 28.7"/73 cm.
* Figures differ by several % because the calculation is approximate.
