Calculation methods for screen dimensions
You can calculate more detailed screen dimension from the screen diagonal. (Unit: m)
PT-LB51NTU/PT-LB51U
PT-LB51SU
* The results above are approximate and may differ slightly from the actual measurements.
Projection size(4:3)
Projection size(16:9)
SH
= SD X 0.0152
SH
= SD X 0.0125
SW
= SD X 0.0203
SW
= SD X 0.0221
LW
= 0.0307 X SD - 0.031
LW
= 0.0335 X SD - 0.0315
LT
= 0.0371 X SD - 0.029
LT
= 0.0405 X SD - 0.0365

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.
