* For WUXGA Type, the shift range in the horizontal direction is up to 15% H when using the lens unit “NP13ZL” to project a screen
exceeding Model 150.
Ex.: When projecting on a 150" screen
The explanation is for a XGA Type projector (4:3 panel) with a NP12ZL lens fitted.
• Please replace the screen dimensions and maximum shift value in the calculations for the WXGA Type and WUXGA
Type projectors (16:10 panel) as well.
According to the tables of screen sizes and dimensions (
→
), H=120" (304.8cm), V=90" (228.6cm).
Adjustment range in the vertical direction: The projected image can be moved upwards 0.5×90" (228.6cm) = 45"
(114cm),, downwards 0.1×90" (228.6cm) = 9" (22cm) (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 0.3×120" (304.8cm) = 36"
(91cm), to the right 0.3×120" (304.8cm) = 36" (91cm).
* Figures differ by several % because the calculation is approximate.
