Example: When projecting on a 16:10 150" screen using the NP54ZL lens:
According to the "Lens types and throw distance (Aspect ratio 16:10)" (

page 000), H (screen width)
= 323.1 cm and V (screen height) = 201.9 cm
Adjustment range in the vertical direction: Upper and lower directions of 0.65 × 201.9 cm ≈ 131 cm
possible movement of the projected screen (when the lens is at the center position).
Adjustment range in the horizontal direction: Right and left directions of 0.25 × 323.1 cm ≈ 81 cm
possible movement of the projected screen.
* Your calculated figure has a few percent margin of error because the calculation formula is ap-
proximate.
