Desk/front projection
Ceiling/front projector
Ex.: When projecting on a 150" screen
According to the tables of screen sizes and dimensions for 16:10 (→ page 206), H = 323.1 cm, V = 201.9 cm.
Adjustment range in the vertical direction: The projected image can be moved upwards 0.5 × 201.9 cm ≈ 101 cm,
(when the lens is at the center position). For a ceiling/front installation, the above figures are inverted.
Adjustment range in the horizontal direction: The projected image can be moved to the left 0.1 × 323.1 cm ≈ 32 cm,
to the right 0.1 × 323.1 cm ≈ 32 cm.
* Figures differ by several % because the calculation is approximate.
