Cautions	when	using	a	DVI	signal
•	 When	the	computer	 has	a	DVI	 output	 connector,	 use	a	commercially	 available	converter	 cable	to	connect	 the	
computer	 to	the	 projector’s	 HDMI	1	or	 HDMI	 2	input	 connector	 (only	digital	 video	signals	 can	be	input). 	Also,	 con-
nect	the	computer’s	 audio	output	 to	the	 projector’s	 BNC	audio	 input	connector. 	In	 this	 case,	 switch	 the	HDMI1	 or	
HDMI2	setting	at	on-screen	menu’s	audio	selection	on	the	projector	to	[BNC]. 	(→	page	112)
	 To	connect	 the	computer’s	 DVI	output	 connector	 to	the	 projector’s	 DisplayPort	 input	connector,	 use	a	commercially	
available	converter.

NOTE:	When	Viewing	a	DVI	Digital	Signal
•	 Turn	off	the	power	of	the	computer	and	projector	before	connecting.
•	 Lower	the 	computer’s 	volume 	setting 	before 	connecting 	an 	audio 	cable 	to 	the 	headphones 	connector. 	When 	using 	with 	a 	computer	
connected to the projector, adjust the volume of both the projector and computer to set the approp\
riate volume level.
•	 If	the	computer	has	a	mini-jack	type	audio	output	connector,	we	recommend	connecting	the	audio	cable	to	that	connector.
•	 When	 a	video	 deck	is	connected	 via	a	scan	 converter,	 etc.,	the	display	 may	not	be	correct	 during	fast-forwarding	 and	rewind-
ing.
•	 Use	 a	DVI-to-HDMI	 cable	compliant	 with	DDWG	 (Digital	 Display	 Working	 Group)	DVI	(Digital	 Visual	Interface)	 revision	1.0	stan-
dard.	The	cable	should	be	within	197"/5	m	long.
•	 Turn	off	the	projector	and	the	PC	before	connecting	the	DVI-to-HDMI	cable.
•	 To	project	a	DVI	digital	signal:	Connect	the	cables,	turn	the	projector	on,	then	select	the	HDMI	input.	Finally,	turn	on	your	PC.
	 Failure	 to	do	 so	may	 not	activate	 the	digital	 output	 of	the	 graphics	 card	resulting	 in	no	 picture	 being	displayed.	 Should	this	happen,	
restart	your	PC.
•	 Some	 graphics	 cards	have	both	analog	 RGB	(15-pin	 D-Sub)	and	DVI	 (or	DFP)	 outputs.	 Use	of	the	 15-pin	 D-Sub	connector	 may	
result in no picture being displayed from the digital output of the grap\
hics card.
•	 Do	not	disconnect	 the	DVI-to-HDMI	 cable	while	 the	projector	 is	running.	 If	the	 signal	 cable	has	been	 disconnected	 and	then	
reconnected,	an	image	may	not	be	correctly	displayed.	Should	this	happen,	restart	your	PC.
•	 The	 COMPUTER	 video	input	connectors	 support	Windows	 Plug	and	Play.	 The	BNC	 video	 input	connector	 does	not	support	 Win-
dows Plug and Play.
•	 A	Mac	signal	adapter	(commercially	available)	may	be	required	to	connect	a	Mac	computer.
	 To	 connect	 a	Mac	 computer	 equipped	with	a	Mini	 DisplayPort	 to	the	 projector,	 use	a	commercially	 available	Mini	DisplayPort	→ 
DisplayPort	converter	cable.

6. Installation and Connections
Portrait projection (vertical orientation)
Portrait	screens	 from	a	computer	 can	be	projected	 by	installing	 the	projec-
tor	in	a	vertical	 orientation. 	All	 the	 screens	 such	as	the	 on-screen	 menu	
will	be	rotated	in	an	counter-clockwise	direction.
The	projector	 is	equipped 	with	 a	sensor 	to	 automatically 	detect 	the	 instal-
lation	state.
When	 the	projector	 is	installed	 in	a	portrait	 configuration	 for	the	 first	 time	
with	 the	lamp	 lit	up,	 a	caution	 message	 to	indicate	 that	the	operating	 time	
of	the	lamp	may	be	shortened	will	be	displayed.
This	message	 will	automatically	 disappear	when	the	installation	 state	of	
the	projector	is	returned	to	the	original	state.
 Precautions during installation
•	 Please	 do	not	 install	 the	projector	 in	a	vertical	 orientation	 on	top	 of	the	 floor	 or	table	 on	its	own. 	The	 air	inlet	 may	
be	obstructed,	resulting	in	the	projector	getting	warm	and	the	possibility	of	fire	and	malfunction	occurring.
•	 For	 vertical	 installation,	 install	the	projector	 with	the	air	inlet	 (filter)	 facing	 downwards. 	A	 stand	 for	supporting	
the	 projector	 needs	to	be	 made	 for	this	 purpose. 	In	 this	 case,	 the	stand	 must	be	designed	 such	that	the	center	
of	gravity	 of	the	 projector	 is	located	 well	within	 the	legs	 of	the	 stand. 	If	 not,	 the	projector	 may	fall	over	 and	result	
in	injury,	damage	and	malfunction.
•	 Do	 not	use	 the	lens	 shift	function	 when	performing	 portrait	projection. 	Use	 the	position	 of	the	 lens	 shift	mecha-
nism	in	the	center	(lens	center).
NOTE:
•	 The	lamp	replacement	time	(as	a	guide)*	is	about	2000	hours	for	portrait	projection.
*	 Replacement	time	is	not	guaranteed.
•	 When	 installing	 in	a	portrait	 configuration	 for	the	 first	 time,	 portrait	 projection	 cannot	be	used	 when	 the	number	 of	lamp	 hours	
used	shown	under	[INFO.]	→	[USAGE	TIME]	→	[LAMP	HOURS	USED]	in	the	on-screen	menu	exceeds	1900	hours.
•	 When	the	[FAN	MODE]	is	set	to	a	mode	other	than	[AUTO],	portrait	projection	cannot	be	used.
Design and manufacturing conditions for the stand
Please	 engage	 an	installation	 service	provider	 for	the	 design	 and	manufacture	 of	the	 customized	 stand	to	be	 used	 for	
portrait	projection. 	Please	ensure	that	the	following	are	complied	with	when	designing	the	stand.
1.	 Maintain	an	opening	of	at	least	310	×	170	mm	so	as	not	to	obstruct	the	air	inlet	/	filter	of	the	projector.
2.	 Maintain	a	distance	 of	at	least	 130	mm	between	 the	projector	 air	inlet	 and	the	floor	 (for	the	opening	 of	the	 filter	
cover).
3.	 Use	the	four	screw	holes	at	the	back	of	the	projector	to	secure	it	to	the	stand.
	 Screw	hole	center	dimension: 	200	×	250	mm
	 Screw	hole	dimension	on	the	projector: 	M4	with	a	maximum	depth	of	8	mm.
*	 Please	design	the	stand	 such	that	the	rear	 legs	 at	the	 back	 of	the	 projector	 do	not	 contact	 the	stand. 	The	 front	
legs	can	be	turned	and	removed.
4.	 Horizontal	adjustment	mechanism	(for	example,	bolts	and	nuts	in	four	locations)
5.	 Please	design	the	stand	such	that	it	does	not	topple	over	easily.
