Ex.: When projecting on a 150" screen
This section is illustrated in the example for PA600X/PA500X
• The following description can apply to the PA550W and PA500U (16:10). To calculate, use screen sizes and the
maximum value for the lens shift for PA550W and PA500U.
According to the tables of screen sizes and dimensions (→ page 204), H = 323.1 cm, V = 201.9 cm.
Adjustment range in the vertical direction: The projected image can be moved upwards 0.6 × 201.9 cm = 121 cm,
downwards 0.1 × 201.9 cm = 20 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 × 323.1 cm = 97 cm,
to the right 0.3 × 323.1 cm = 97 cm.
* Figures differ by several % because the calculation is approximate.
