J Calculation methods for screen dimensions
You can calculate more detailed screen dimensions from the screen diagonal.
16:9 size 2.35:1 size
Screen height (SH) = SD (m) × 0.490 = SD (m) × 0.392
Screen width (SW) = SD (m) × 0.872 = SD (m) × 0.920
Minimum distance (LW) = SD (m) × 1.189 − 0.04 = SD (m) × 1.256 − 0.04
Maximum distance (LT) = SD (m) × 2.378 − 0.05 = SD (m) × 1.899 − 0.05
NOTE:
You can tilt the projector body less than approximately ±30 ° vertically and ±10 ° horizontally. •
Overtilting may result in shortening the component’s life.
Do not cover the air exhaust/intake ports or place anything within 50 cm (19 5/8") of them. •
