(Example) When using to project on a 150" screen
According to the “Table of screen sizes and dimensions” (→ page 124), H = 120.0''/304.8 cm, V =
90.0''/228.6 cm.
Adjustment range in the vertical direction: the projected image can be moved upwards 0.50 ×
90.0''/228.6 cm ≈ 45.0''/114 cm (when the lens is at the center position).
Adjustment range in the horizontal direction: the projected image can be moved to the left 0.28 ×
120.0''/304.8 cm ≈ 33.6''/85 cm, to the right approximately 33.6''/85 cm.
* Figures dier by several % because the calculation is approximate.
