Things to note when installing projectors
•	 Leave	60	cm/23.6"	or	over	space	between	the	projectors	when	projectors	are	installed	side	by	side,	so	that	the	
intake	vents	of	the	projectors	are	not	obstructed.	In	addition,	leav e	a	space	of	at	least	30	cm/11.8"	between	the	
intake	vent	and	the	wall	and	at	least	70	cm/27.6"	between	the	exhaust	vent	and	the	wall.	When	the	air	intake	and	
discharge	outlet	are	obstructed,	the	temperature	inside	the	projector	will	rise	and	this	may	result	in	a	malfunction.
60	cm/23.6"	or	greater
•	 Do	not	directly	stack	projector	units.
 WARNINGProjectors	stacked	directly	could	fall	and	cause	injury .	The	projector(s)	could	also	become	
damaged	or	broken.
•	 Example	of	multiple	projectors	installed	together
	 When	using	multiple	projectors	together	for	multi	screen	projection,	be	sure	to	set	them	up	in	a	specialized	projector	
cabinet	like	the	one	that	follows.

 WARNING
Please	request	the	dealer	for	special	installation	services	such	as	when	mounting	the	projector	to	the	ceiling.	Nev er	
carry	out	the	installation	by	yourself.	The	projector	may	fall	down	and	result	in	injury .	Please	use	a	sturdy	cabinet	
that	can	withstand	the	weight	of	the	projector	for	the	installation.	Please	do	not	pile	up	the	projectors	directly	on	
top	of	one	another.
NOTE:
•	 For	the	range	of	the	projection	distance,	please	refer	to	the	Appendix	“Throw	distance	and	screen	size”.	(→ page 156)

❷ Displaying Two Pictures at the Same Time
The	projector	has	a	feature	that	allows	you	to	view	two	different	signals	simultaneously.	You	hav e	two	modes:	picture	
in	picture	(PIP)	mode	and	picture	by	picture	(PICTURE	BY	PICTURE)	mode.
The	projection	video	in	the	first	screen	display	is	known	as	the	main	display	while	the	projection	video	that	is	called	
out	subsequently	is	known	as	the	sub-display.
Select	the	projection	function	under	[DISPLAY]	→	[PIP/PICTURE	BY	PICTURE]	→	[MODE]	in	the	on-screen	menu	
(the	default	factory	setting	when	shipped	is	PIP).	(→	page	92)
•	 A	single	screen	is	projected	when	power	is	turned	on.

A	small	sub-display	is	displayed	inside	the	main	display.
The	sub-display	can	be	set	up	and	adjusted	as	follows.	(→	page	93)
•	 Select	whether	to	display	the	sub-display	at	the	top	right,	top	left,	bottom	right	
or	bottom	left	of	the	screen	(the	size	of	the	sub-display	can	be	selected	and	
the	position	can	be	fine-tuned)

❸ Displaying a Picture Using [EDGE BLENDING]
A	high	resolution	video	can	be	projected	on	an	even	bigger	screen	by	combining	multiple	projectors	on	the	left,	right,	
top	and	bottom.
This	projector	is	equipped	with	an	“EDGE	BLENDING	Function”	that	makes	the	edges	(boundaries)	of	the	projection	
screen	indistinguishable.
NOTE:
•	 For	projector	throw	distances,	refer	to	“Throw	distance	and	screen	size”	on	page	156.
•	 Before	performing	the	Edge	Blending	function,	place	the	projector	in	the	correct	position	so	that	the	image	becomes	square	in	
the	appropriate	size,	and	then	make	optical	adjustments	(lens	shift,	focus,	and	zoom).
•	 Adjust	the	brightness	of	each	projector	using	[ADJUST]	under	[LIGHT	MODE].	After	adjusting	the	brightness,	you	can	keep	the	
set	brightness	level	by	turning	ON	the	[CONSTANT	BRIGHTNESS]	mode.	In	addition,	use	[REF.	WHITE	BALANCE]	to	adjust	the	
[CONTRAST]	and	[BRIGHTNESS].
Before	explaining	use	of	the	Edge	Blending	function
This	section	explains	the	case	for	“Example:	Placing	two	projectors	side	by	side”.	As	shown,	the	projected	image	on	
the	left	is	referred	to	as	“Projector	A”	and	the	projected	image	on	the	right	is	referred	to	“Projector	B”.	Unless	otherwise	
specified	hereinafter,	the	“projector”	is	used	to	mean	both	A	and	B .

Preparation:
•	 Turn	on	the	projector	and	display	a	signal.
•	 When	performing	settings	or	adjustments	using	the	remote	control,	enable	the	[CONTROL	ID]	so	as	not	to	activate	
the	other	projectors.	(→	page	113)
Setting the overlap of projection screens
①
	Enable	[EDGE	BLENDING].
1. Press the MENU button.
	 The	menu	will	be	displayed.

5.	 Select	[CONTROL]	→	[ON]	and	press	the	ENTER	button.
	 Each	[TOP],	[BOTTOM],	[LEFT],	[RIGHT],	and	[BLACK	LEVEL]	has	its	own	[CONTROL],	[MARKER],	[RANGE],	
and	[POSITION].
•	 For	Projector	A,	set	the	[CONTROL]	for	the	[TOP],	[LEFT]	and[BOTT OM]	to	[OFF].	Similarly	for	Projector	B,	set	
the	[CONTROL]	for	the	[TOP],	[RIGHT]	and	[BOTTOM]	to	[OFF].
②	Adjust	[RANGE]	and	[POSITION]	to	determine	an	area	of	overlapped	edges	of	images	
projected from each projector.
Turning	on	[MARKER]	will	display	markers	in	magenta	and	green.
The	magenta	marker	is	used	for	[RANGE]	and	green	one	for	[POSITION].

	 Use	the	◀	or	▶	button	to	adjust	the	overlapped	area.
TIP:
•	 Adjust	to	overlap	one	projector’	marker	with	the	other	projector’s	marker.
2	 Adjust	[POSITION].
	 Use	the	◀	or	▶	button	to	align	one	edge	with	the	other	edge	of	overlapped	images.
TIP:
•	 When	displaying	a	signal	with	a	different	resolution,	perform	the	Edge	Blending	function	from	the	start.	
•	 Setting	of	[MARKER]	will	not	be	saved	and	return	to	[OFF]	when	the	projector	is	turned	off.	
•	 To	display	or	hide	the	marker	while	the	projector	is	running,	turn	on	or	off	[MARKER]	from	the	menu.
