(Example) When using to project on a 150" screen
According to the "Table of screen sizes and dimensions" (→ page 67) , H = 127.2"/323.1 cm, V = 79.5"/201.9 cm.
Adjustment range in the vertical direction: the projected image can be moved upwards 0.60 × 79.5"/201.9 cm ≈
47.7"/121 cm (when the lens is at the center position).
Adjustment range in the horizontal direction: the projected image can be moved to the left 0.29 × 127.2"/323.1 cm
≈ 36.9"/94 cm, to the right approximately 36.9"/94 cm.
