NEC PA1004UL-W User Manual page 200

Example: When projecting on a 150" screen using the NP40ZL lens:
According to the "Tables of screen sizes and dimensions" (→ page 174), H (screen width) = 323.1
cm and V (screen height) = 201.9 cm
Adjustment range in the vertical direction: The projected image can be moved upward 0.50 ×
201.9 cm ≈ 111 cm and downward 0.1 × 201.9 cm ≈ 20 cm (when the lens is at the center position).
Adjustment range in the horizontal direction: The projected image can be moved to the left 0.20 ×
323.1 cm ≈ 65 cm, and this applies to the right direction which means approx. 65 cm.
* Your calculated figure has a few percent margin of error because the calculation formula is approximate.
NOTE:
• Use NP11FL at the home position. If necessary, fine-adjust the position of the projected image using the lens shift function.
• The NP44ML must be fixed to the projector using the separately sold support kit (NP02LK). Loosen the screws of the support bracket,
you can fine-adjustment of the lens shift.
