Installing the Projector (Cont.)

Projection Distances and Screen Sizes

Lenses that can be used are a 3 : 1 ~ 7 : 1 zoom lens and a 1.5 : 1 fixed-focus lens. With a zoom lens used, you have a wider latitude in selecting projection distance and installation space than with a fixed lens.

For how to install the lens, consult the dealer who installed and adjusted your projector or service center.

Relationship of screen width vs. projection distance

	600							WIDE 3:1
	500
Screen Size	400
		Fixed-Focus Lens
(inch)	300		1.5 : 1
									TELE 7:1
	200							Zoom Lens
	100
										Projection
									40	Distance (m)
	0	5	10	15	20	25	30	35		45

In the shaded areas in the above graph, the projected image may be partially distorted or missed out depending on the distance between the projector and the screen. To project an image with no image distortion or missing, we recommend you to use the projector in the areas defined with solid lines in the graph.

Adjustable range of the lens

Lens		Screen Size (Type)		Projection Distance (m)		Remarks
GL-M4023SZ zoom lens		80	– 300	5.06	– 18.65	3:1 wide
		(80	– 600)	(5.06	– 37.19)
		60	– 200	8.65	– 28.56	7:1 tele
		(60	– 300)	(8.65	– 42.79)
GL-M4015S fixed-focus lens		69	– 208	2.09 – 6.50		––––––––
		(65	– 250)	(1.97 – 7.83)
The numbers in (	) represent the minimum to maximum adjustable range.

Connecting to Various Devices

*Before connection, be sure to turn off the projector and connected devices.

*Read the manual which comes with each device thoroughly.

Signals that Can Be Input to the Projector

The following signals can be input to the projector:

■Video signals

(1) Response to color systems

Color system	NTSC 480i	NTSC4.43	PAL	SECAM
Input terminal
VIDEO*3	‡	‡	‡	‡
Y/C*3	‡	‡*1	‡	- - - - -
Y, PB/B-Y, PR/R-Y	‡*2	‡*2	‡*2	‡*2
G, B, R, H/CS, V	‡*2	‡*2	‡*2	‡*2

*1 : Responds if Y/C output is available.

*2 : Signifies that component signals (“Y, PB, PR ” / “ Y, B-Y, R-Y” / “G, B, R, H/CS, V”) conform to the signal timing (synchroniza- tion and video period) of each color system. The color systems are used for convenience only.

*3 : To use these terminals, a video board (separately sold) is required.

(2) Response to double density (*1), high-vision signals

Input terminal	NTSC*2	PAL*3	High-vision signal
Y, PB/B-Y, PR/R-Y	‡	‡	‡
G, B, R, H/CS, V	‡	‡	‡

*1 : Signals whose density of scanning lines/field is twice as high.

*2 : Responds to signals whose horizontal scanning frequency is 31.5 kHz. NTSC can be made twice as dense by a line doubler (separately available: recommended article). Also, possible to respond to fully-specified, decoded 525P progressive sig- nals.

*3 : Responds to signals whose horizontal scanning frequency is 33.5 kHz. PAL can be made twice as dense by a line doubler (separately available: recommended article).

Notes

•DTV-format signals (480i, 480p, 720p, 1080i) can be input into this unit (Y, PB/B-Y, PR/R-Y input terminals). For details about DTV-format signals (480i, 480p, 720p, 1080i) compatible with this unit, refer to page 66.

■Computer signals

•Signals with the following resolutions can be input to the input terminal of RGB IN-1 (PC) or RGB IN-2 (G, B, R, H/Cs, V). (The following signals are preset.)

Screen resolution (standard name)			Horizontal frequency	Vertical frequency	Scanning method
640	⋅ 400 (PC-9801)		24.8kHz	56.4Hz	Non-interlace
640	⋅ 350 (VGA1)		31.5kHz	70.1Hz	Non-interlace
640	⋅ 480 (VGA3)		31.5kHz	59.9Hz	Non-interlace
640	⋅ 480 (Macintosh 13”)		35.0kHz	66.7Hz	Non-interlace
640	⋅ 480 (VGA VESA)		37.5kHz	75.0Hz	Non-interlace
800	⋅ 600 (SVGA1)		37.9kHz	60.3Hz	Non-interlace
800	⋅ 600 (SVGA2)		48.1kHz	72.2Hz	Non-interlace
832	⋅ 624 (Macintosh16”)		49.7kHz	74.6Hz	Non-interlace
1024		⋅ 768 (XGA1)	48.4kHz	60.0Hz	Non-interlace
1024		⋅ 768 (XGA2)	56.5kHz	70.1Hz	Non-interlace
1024		⋅ 768 (Macintosh 19”)	60.2kHz	74.9Hz	Non-interlace
1152 ⋅ 870 (Macintosh 21”)			68.7kHz	75.0Hz	Non-interlace
1280		⋅ 1024 (SXGA1)	64.0kHz	60.0Hz	Non-interlace
1280		⋅ 1024 (SXGA2)	70.8kHz	67.0Hz	Non-interlace
1360		⋅ 1024 (SXGA3: Mac Board)	80.0kHz	75.1Hz	Non-interlace

Notes

• Interlace signals are not handled.

• Some signals other than listed above can be displayed. But they require adjustment. Even some of the signals listed above may require adjustment depending on the video board used.

• When a signal other than listed above is input, the screen could be partially erased or an unneeded fold-over screen could appear.

• Even signals in the frequency range that can be input may not be displayed normally depending on the type of the signal.

• Composite sync.(Cs) and G on sync. signals can not handled depending on the devices connected.
