* For WUXGA Type, the shift range in the horizontal direction is up to 15% H when using the lens unit “Replacement Lens Type8” 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 Replacement Lens Type2
lens
fitted.
• Please replace the screen dimensions and maximum shift value in the calculations for the WXGA Type and WUXGA Type projec-
tors (16:10 panel) as well.
According to the tables of screen sizes and dimensions (
→
), H = 304.8 cm, V = 228.6 cm.
Adjustment range in the vertical direction: The projected image can be moved upwards 0.5 × 228.6 cm = 114 cm, downwards
0.1 × 228.6 cm = 22 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 0.3 × 304.8 cm = 91 cm, to the right
0.3 × 304.8 cm = 91 cm.
* Figures differ by several % because the calculation is approximate.
