Setting Up; Screen Size And Throw Distance - Panasonic PT-LB51SE Operating Instructions Manual

Setting up

Screen size and throw distance

You can adjust the projection size with 1.2x zoom lens. Calculate and define the throw distance as follows.
Projected image
Projection size (4 : 3)
Screen Screen height
diagonal (SD)
33" (0.84 m) 0.50 m (1'7")
40" (1.02 m) 0.61 m (2')
50" (1.27 m) 0.76 m (2'5")
60" (1.52 m) 0.91 m (2'11")
70" (1.78 m) 1.07 m (3'06")
80" (2.03 m) 1.22 m (4')
90" (2.29 m) 1.37 m (4'5")
100" (2.54 m) 1.52 m (4'11")
120" (3.05 m) 1.83 m (6')
150" (3.81 m) 2.29 m (7'6")
200" (5.08 m) 3.05 m (10')
250" (6.35 m) 3.81 m (12'6")
300" (7.62 m) 4.57 m (14'11")
* 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. (Unit: m)
Projection size(4:3)
SH = SD X 0.0152
SW = SD X 0.0203
LW = 0.0307 X SD - 0.031
LT = 0.0371 X SD - 0.029
* The results above are approximate and may differ slightly from the actual measurements.
NOTE:
• Do not use the projector at a raised or a horizontally tilted position as it may cause
malfunction of the projector.
• Make sure the projector lens surface is parallel with the screen. 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.
