Before Setting Up Your Projector (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 9), 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. 11
