*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	Others
Minimum Projection Distance	LW=0.031xSD/0.0254-0.038
Maximum Projection Distance	LT=0.037xSD/0.0254-0.038
For 16:9 aspect ratios, the following formula can be used to calculate the
projection distance.
Minimum Projection Distance	LW=0.033xSD/0.0254-0.038
Maximum Projection Distance	LT=0.040xSD/0.0254-0.038
