Getting Started

NGLISH - 15

Setting up

You can adjust the projection size with 1.2x zoom lens. Calculate and define the throw distance as follows.

* All measurements above are approximate and may differ slightly from the actual measurements.

J Calculation methods for screen dimensions

You can calculate more detailed screen dimension from the screen diagonal.
Screen width (SW) and screen height (SH)

SW (m) = SD (") x 0.0203

SH (m) = SD (") x 0.0152

Minimum distance (LW) and maximum distance (LT)

PT-LB80NTU: LW (m) = 0.0296 x SD (") - 0.039

LT (m) = 0.0358 x SD (") - 0.047

PT-LB75NTU: LW (m) = 0.0292 x SD (") - 0.036

LT (m) = 0.0351 x SD (") - 0.044

* The results above are approximate and may differ slightly from the actual measurements.

NOTE:

• See “Screen size and throw distance for 16:9 aspect ratio” on page 47.
• 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.
