Adjusting	Clock	and	Phase	[CLOCK/PHASE]
This	allows	you	to	manually	adjust	CLOCK	and	PHASE.
CLOCK �������������������Use this item to fine tune the computer image or to remove any vertical banding that might appear � This 
function adjusts the clock frequencies that eliminate the horizontal ban\
ding in the image�
This adjustment may be necessary when you connect your computer for the first time�
PHASE �������������������Use  this  item  to  adjust  the  clock  phase  or  to  reduce  video  noise,  dot  interference  or  cross  talk�  (This  is 
evident when part of your image appears to be shimmering�)
Use [PHASE] only after the [CLOCK] is complete�
NOTE:	The	[CLOCK]	and	[PHASE]	items	are	available	for	RGB	signals	only.

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	malfunction.
•	 The	 adjustments	 for	[CLOCK],	 [PHASE],	[HORIZONTAL],	 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	 frequency,	
its	adjustments	will	be	called	up	and	applied.
	 To	delete	 adjustments	 stored	in	memory,	 from	the	menu,	 you	select	 [RESET]	→	[CURRENT	 SIGNAL]	and	reset	
the	adjustments.
[BLANKING]
Adjusts	the	display	range	(blanking)	at	the	top,	bottom,	left	and	right	edges	of	the	input	signal.
Selecting	Overscan	Percentage	[OVERSCAN]
Select	overscan	percentage	(Auto,	0%,	5%	and	10%)	for	signal.

AUTO
The	projector	will	automatically	determine	the	incoming	signal	and	display	it	in	its	aspect	ratio. 	The	projector	may	erroneously	determine	the	aspect	ratio	depending	on	its	signal.	If	this	occurs,	select	the	appropriate	aspect	ratio	from	the	following.

NATIVE
The	projector	displays	the	current	image	in	its	true	resolution	when	the	incoming	computer	signal	has	a	lower	or	higher	resolution	than	the	projector’s	native	resolution. 	(→	page	2)When	the	incoming	computer	signal	has	a	higher	resolution	than	the	projector's	native	resolution,	the	center	of	an	image	will	be	displayed.
LETTER	BOXThe	image	of	a	letterbox	signal	(16:9)	is	stretched	equally	in	the	horizontal	and	vertical	directions	to	fit	the	screen.
WIDE	SCREENThe	image	of	a	squeeze	signal(16:9)	is	stretched	left	and	right	in	16:9.
ZOOMThe	image	of	a	squeeze	signal	(16:9)	is	stretched	left	and	right	in	4:3.Parts	of	the	displayed	image	are	cropped	at	the	left	and	right	edges	and	therefore	not	visible.

TIP:
•	 Image	position	can	be	adjusted	vertically	using	[POSITION]	when	the	[16:9],	[15:9],	or	[16:10]	aspect	ratios	are	selected.
•	 The	term	“letterbox”	 refers	to	a	more	 landscape-oriented	 image	when	compared	 to	a	4:3	 image,	 which	is	the	 standard	 aspect	
ratio for a vide source.
	 The	letterbox	signal	has	aspect	ratios	with	the	vista	size	“1.85:1”	or	cinema	scope	size	“2.35:1”	for	movie	film.
•	 The	term	“squeeze”	refers	to	the	compressed	image	of	which	aspect	ratio	is	converted	from	16:9	to	4:3.
[INPUT RESOLUTION]
The	resolution	 is	assigned	 automatically	 when	the	resolution	 of	the	 input	 signal	 from	the	computer	 video	input	terminal	
or	BNC	video	input	terminal	(analog	RGB)	cannot	be	distinguished.

Using Noise Reduction [NOISE REDUCTION]
When	projecting	 a	video 	image, 	you 	can 	use 	the 	[NOISE 	REDUCTION]	 function	to 	reduce 	the 	screen 	noise 	(roughness	
and	 distortion). 	This	 device	 is	equipped	 with	three	 types	 of	noise	 reduction	 functions.	Select	 the	function	 according	 to	
the	type	 of	noise. 	Depending	 on	the	 noise	 level,	the	noise	 reduction	 effect	can	be	set	 to	[OFF],	 [LOW],	 [MEDIUM]	 or	
[HIGH].	[NOISE	REDUCTION]	can	be	selected	for	SDTV,	HDTV	signal	and	component	signal	input.

This	function	allows	you	to	select	an	interlaced-to-progressive	conversion	process	for	video	signals.
NORMAL ����������������Automatically distinguishes a moving image from a static image to create a distinct image� Please select 
[MOVIE] if there are any obvious jitter and noises�
