Projection Distance Formula
D: Projection image size (")
Example) Enter 80 in D for the 80" projection image size.
Unit: m (inches)
| Projection distance L (minimal length) | Projection distance L (maximal length) |
|---|---|
| L = 0.030347 × D − 0.0478 (L = 1.194766 × D − 1.8818) |
L = 0.063337 × D − 0.0448 (L = 2.493567 × D − 1.7646) |
Lens Shift Range
X: 36
Y: 85
VS+ = 85 − 2.361 × (HS+ or HS−) [%]
VS− = −85 + 2.361 × (HS+ or HS−) [%]
HS+ = HS− = 36 − 0.424 × (VS+) [%]
HS+ = HS− = 36 + 0.424 × (VS−) [%]
