4. Multi-Screen Projection
❶ Things that can be done using multi-screen projection
This	projector	can	be	used	singly	or	arranged	in	multiple	units	for	multi-screen	projection.
We	will	introduce	an	example	using	two	projection	screens	here.
Case 1
Using	a	single	projector	to	project	two	types	of	videos	at	the	same	time
[PIP/PICTURE	BY	PICTURE]
Case 2
Using	four	projectors	(resolution:	WUXGA)	 to 	 project 	 video 	 with 	 a 	 resolution 	 of 	 2560 	 × 	 1600 	 pixels

Things to note when installing projectors
•	 Leave	1	m 	or 	o ver 	space 	betw een 	the 	projectors 	when 	projectors 	are 	installed 	side 	b y 	side , 	so 	that 	the 	intak e 	and 	
exhaust	vents	of 	the 	projectors 	are 	not 	obstr ucted.	In 	addition, 	lea ve 	a 	space 	of 	at 	least 	30 	cm 	betw een 	the 	intak e/
exhaust	vent	and 	the 	w all.	When 	the 	air 	intak e 	and 	discharge 	outlet 	are 	obstr ucted, 	the 	temper ature 	inside 	the 	
projector	will	rise	and	this	may	result	in	a	malfunction.
1	m	or	greater
•	 Two	projectors	can 	be 	stac ked 	on 	top 	of 	each 	other 	(ST ACK 	setting).	(→	page	138)	Do	not 	attempt 	to 	directly 	stac k 	
three	or	more 	projectors .	When 	the 	projectors 	are 	piled 	up 	on 	top 	of 	one 	another , 	the y 	ma y 	f all 	do wn, 	resulting 	in 	
damage	and	failure.
•	 Installation	example	when	using	3	or	more	projectors
	 The	following	installation 	is 	recommended 	when 	installing 	a 	combination 	of 	3 	or 	more 	projectors 	f or 	m ulti-screen

❸ Displaying a Picture Using [EDGE BLENDING]
A	high	resolution 	video 	can 	be 	projected 	on 	an 	e ven 	bigger 	screen 	b y 	combining 	m ultiple 	projectors 	on 	the 	left, 	r ight, 	
top	and	bottom.
This	projector	is 	equipped 	with 	an 	“EDGE 	BLENDING 	Function”	that 	mak es 	the 	edges 	(boundar ies) 	of 	the 	projection 	
screen	indistinguishable.
NOTE:
•	 For	projector	throw	distances,	refer	to	“Throw	distance	and	screen	size”	on	page	153.
•	 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 	[CONST ANT 	BRIGHTNESS] 	mode. 	In 	addition, 	use 	[REF . 	WHITE 	BALANCE] 	to 	adjust 	the 	
[CONTRAST]	and	[BRIGHTNESS].
Before	explaining	use	of	the	Edge	Blending	function
This	section	e xplains 	the 	case 	f or 	“Example:	Placing 	tw o 	projectors 	side 	b y 	side”.	As 	sho wn, 	the 	projected 	image 	on 	
the	left	is 	ref erred 	to 	as 	“Projector 	A”	and 	the 	projected 	image 	on 	the 	r ight 	is 	ref erred 	to 	“Projector 	B”.	Unless 	otherwise 	
specified	hereinafter,	the	“projector”	is 	 used 	 to 	 mean 	 both 	 A 	 and 	 B.
