Calculation methods

SW (m) = SD (") x 0.0215

SH (m) = SD (") x 0.0135

LW (m) = 0.0311 x SD (") - 0.040

LT (m) = 0.0372 x SD (") - 0.044

NOTE:

See “Screen size and throw distance for 16:9/4:3 aspect ratio” on page 54.

• Do not use the projector at a raised or a horizontally tilted position as it may cause malfunction of the projector.

• You can tilt the projector body 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.
