* 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.
