*1 The “i” appearing after the resolution indicates an interlaced signal. *2 The following symbols are used to indicate picture quality.

AA Maximum picture quality can be obtained.

ASignals are converted by the image processing circuit before picture is projected

BSome loss of data occurs to make projection easier.

*3 Signals with “OK” in the Resizing column can be set using the RESIZING command in the POSITION menu. (Refer to page 40.)

*4 Signals that are compatible with the FRAME LOCK function. (page 40.)

Pin + is spare.

Pins &–*, ,and - are for earth.

Pins . and 1 functions are only valid when supported by the computer

Projection dimensions calculation methods

If the screen size (diagonal) is SD (m), then the following formula is used to calculate the projection distance for the wide lens position (LW) and the projection distance for the telephoto lens position (LT).

		4:3
	SH
	H1
LW/LT			SW
PT-LC80E	PT-LC76E / PT-LC56E

LW=0.030xSD/0.0254-0.037 LW=0.031xSD/0.0254-0.038

LT=0.036xSD/0.0254-0.037 LT=0.037xSD/0.0254-0.038

For 16:9 aspect ratios, the following formula can be used to calculate the projection distance.

PT-LC80E	PT-LC76E / PT-LC56E
LW=0.032xSD/0.0254-0.037	LW=0.033xSD/0.0254-0.038
LT=0.039xSD/0.0254-0.037	LT=0.040xSD/0.0254-0.038
