J Calculation methods for screen dimensions
You can calculate more detailed screen dimension from the screen diagonal. (Unit: m)
PT-LB51NTU/PT-LB51U
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
PT-LB51SU
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 = 0.0304 X SD - 0.029 LW = 0.0332 X SD - 0.032
LT = 0.0368 X SD - 0.041 LT = 0.0401 X SD - 0.038
* 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.

Connections
Before connection to the projector
Read and follow the operating and connecting instructions of each peripheral device.
The peripheral devices must be turned off.
Use cables that match each peripheral device to be connected.
If the input signal is affected by signal jitter, the projected image may have poor image quality and timebase
correction is effective.
Confirm the type of video signals. See “List of compatible signals” on page 44.
Only one audio system circuit is available for each of the COMPUTER AUDIO IN and AUDIO IN L-R
connectors, so if you change the audio input source, you will need to remove and insert the appropriate
plugs.
If the signal cables are disconnected or if the power supply for the computer or video deck is turned off while
“DIGITAL ZOOM” or “INDEX-WINDOW” is being used, these functions will be canceled.
See “Enlarging the centered area” on page 26.
Getting Started
See “Projecting an image in INDEX-WINDOW mode” on page 25.
