Setting up
You can adjust the projection size with 2.0x zoom lens. Calculate and define the throw distance as follows.
All measurements and the calculation results bellow are approximate and may differ from the actual measurements.

Calculation methods for screen dimensions
You can calculate more detailed screen dimension from the screen diagonal.
16 : 9 size
Screen width (SW) and screen height (SH)
SW (m)= SD (m) x 0.872
SH (m) = SD (m) x 0.490
Minimum distance (LW) and maximum distance (LT)
LW (m) = SD (m) x 1.189 - 0.04
LT (m) = SD (m) x 2.378 - 0.05
2.35 : 1 size
Screen width (SW) and screen height (SH)
SW (m)= SD (m) x 0.920
SH (m) = SD (m) x 0.392
Minimum distance (LW) and maximum distance (LT)
LW (m) = SD (m) x 1.256 - 0.04
LT (m) = SD (m) x 2.512 - 0.05

NOTE:
• Do not use the projector at a raised or a horizontally tilted position as it may cause
malfunction of the projector.
• Make sure the projector lens surface is parallel with the screen. You can tilt the projector
body less than approximately ± 30° vertically. Overtilting may result in shortening the
component’s life.
• For the best quality of the projection image, install a screen where sun light or room light
does not shine directly onto the screen. Close window shades or curtains to block the lights.
