(Example calculation) If projecting on a 300 inch screen using an L4K-15ZM lens unit
According to the “Table of screen sizes and dimensions” (
→ page 149 ), H = 261.5"/664.1 cm, V = 147.1"/373.6 cm.
Adjustment range in the vertical direction: the projected image can be moved upwards 0.55 × 147.1"/373.6 cm ≈
81"/205 cm, downwards approximately 81"/205 cm (when the lens is at the center position). Adjustment range in the
horizontal direction: the projected image can be moved to the left 0.22 × 261.5"/664.1 cm
≈ 58"/146 cm, to the right
approximately 58"/146 cm.
* Figures differ by several % because the calculation is approximate.
