9. Appendix 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. The lens can be shifted within the range shown below. Description of symbols: V indicates vertical (height of the projected image), H indicates horizontal (width of the projected image). NOTE: The lens shift function cannot be used when using the NP16FL (PX750U) and NP06FL (PX700W/PX800X) lens. Desk/front projection Width of projected image 0.5V 1V Height of projected image 0.1H 1H 0.1H Ceiling/front projector 0.1H 1H 0.1H Height of projected image 1V 0.5V Width of projected image Ex.: When using the PX750U to project on a 150" screen According to the tables of screen sizes and dimensions for 16:10 (→ page 204), H = 323.1 cm, V = 201.9 cm. Adjustment range in the vertical direction: The projected image can be moved upwards 0.5 × 201.9 cm ≈ 101 cm, (when the lens is at the center position). For a ceiling/front installation, the above figures are inverted. Adjustment range in the horizontal direction: The projected image can be moved to the left 0.1 × 323.1 cm ≈ 32 cm, to the right 0.1 × 323.1 cm ≈ 32 cm. * Figures differ by several % because the calculation is approximate. 208
