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-LB80NTE: LW (m) = 0.0296 x SD (") - 0.039

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

PT-LB75NTE: 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 49.

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.
