Setting up
You can adjust the projection size with 2.0x 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.
