Panasonic PT-LB80U User Manual

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.

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.
