Troubleshooting on viewing 3D images
If	images	will 	not 	be 	displayed 	in 	3D 	or 	3D 	images 	appear 	as 	2D, 	check 	the 	following 	table. 	Also 	refer 	to 	the 	user's 	
manual	accompanied	with	your	3D	content	or	LCD	shutter	eyeglasses.
Possible causesSolutions•	 The	content	you	are	playing	back	is	not	compatible	with	3D.•	 Play	back	a	content	compatible	with	3D.
•	 The	3D	mode	was	turned	off	for	the	selected	source.•	 Use	the	projector's 	menu 	to 	turn 	on 	3D 	mode 	for 	the 	selected 	source. (→	page	61)•	 You	are	not 	using 	our 	recommend ed 	LCD 	shutter 	eyeglasses.•	 Use	our	recommended	LCD	shutter	eyeglasses.	(→	page	39)•	 If	the	shutter 	of 	your 	LCD 	shutter 	eyeglasses 	cannot 	synchronize	with	the	currently 	projected 	source, 	the 	following 	are 	possible 	causes:-	 Your	LCD	shutter	eyeglasses	are	not	switched	on.•	 Switch	on	your	LCD	shutter	eyeglasses.-	 The	battery	in	the	LCD	shutter	eyeglasses	ran	down.•	 Recharge	the	battery	or	replace	it.
-	 The	correct	eyeglass	method	is	not	selected.	•	 Change	the	eyeglass 	method 	for 	3D 	by 	using 	the 	menu.. 	(→ page	61)
-	 The	viewing	distance 	between 	the 	viewer 	and 	the 	screen 	is 	too	far.
•	 Move	closer	to	the	screen	until	the	viewer	gets	3D	images.	•	 Or	use	the 	projector's 	menu 	to 	select 	[NON-INVERT] 	for 	[L/R 	INVERT].	
-	 There	are	brigh t 	light 	sources 	or 	other 	projectors 	near 	the 	viewer.
•	 Keep	light	sources	or	other	projectors	away	from	the	viewer.•	 Do	not	look	toward	a	bright	light	source.•	 Or	use	the 	projector's 	menu 	to 	select 	[NON-INVERT] 	for 	[L/R 	INVERT].	•	 If	your	computer 	is 	not 	set 	for 	3D 	viewing, 	the 	following 	are 	possible	causes:-	 Your	computer	does 	not 	meet 	the 	requirements 	for 	3D	viewing.•	 Check	to	see 	if 	your 	comput er 	meets 	the 	requirements 	provided	in	your	user's	manual	included	with	your	3D	content.-	 Your	computer	is	not	set	for	3D	output.•	 Set	your	computer	for	3D	output.-	 The	resolution	of	output	signal	is	out	of	range.•	 Select	the	resolution	of	output	signal	supporting	3D.	-	 The	refresh	rate	of	output	signal	is	out	of	range.•	 Change	the	refresh	rate	to	120Hz.

Adjusting Horizontal/Vertical Position [HORIZONTAL/VERTICAL]
Adjusts	the	image	location	horizontally	and	vertically.
-	 An	image	can	be 	 distorted 	 during 	 the 	 adjustment 	 of 	 [CLOCK] 	 and 	 [PHASE]. 	 This 	 is 	 not 	 a 	 malfunction.
-	 Your	manual	adjustments 	for 	[CLOCK], 	[PHASE], 	[HORIZONT AL], 	and 	[VERTICAL] 	will 	be 	stored 	in 	memory 	
for	the	current 	signal. 	The 	next 	time 	you 	project 	the 	signal 	with 	the 	same 	resolution, 	horizontal 	and 	vertical

Selecting Aspect Ratio [ASPECT RATIO]
The	term	“aspect	ratio”	refers	to	the	ratio	of	width	to	height	of	a	projected	image.
The	projector	automatically	determines	the	incoming	signal	and	displays	it	in	its	appropriate	aspect	ratio.
