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.
NOTE:	The	[HORIZONTAL]	and	[VERTICAL]	items	are	not	available	for	VIDEO,	S-VIDEO,	HDMI,	VIEWER,	NETWORK,	and	USB	
DISPLAY.
-	 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]	or	[ALL	
DATA]	and	reset	the	adjustments.

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.
•	This	table	shows	typical	resolutions	and	aspect	ratios	that	most	computers	support.

OptionsFunction
AUTO
The	 projector	 will	automatically	 determine	the	incoming	 signal	and	display	 it	in	 its	 aspect	
ratio. 	(→ next	page)
The	projector	 may	erroneously	 determine	the	aspect	 ratio	depending	 on	its	signal. 	If	 this	
occurs,	select	the	appropriate	aspect	ratio	from	the	following.4:3The	image	is	displayed	in	4:3	aspect	ratio.16:9The	image	is	displayed	in	16:9	aspect	ratio.15:9The	image	is	displayed	in	15:9	aspect	ratio.16:10The	image	is	displayed	in	16:10	aspect	ratio.WIDE	ZOOM
(P420X/P350X)
The	image	is	stretched	left	and	right. 	
Parts	of	the	 displayed	 image	are	cropped	 at	the	 left	and	 right	 edges	 and	therefore	 not	
visible.
LETTERBOX
(P350W)The	 image	 of	a	letterbox 	signal 	is	 stretched 	equally 	in	 the	 horizontal 	and	 vertical 	directions	
to	 fit	the	 screen. 	Parts	 of	the	 displayed	 image	are	cropped	 at	the	 top	and	 bottom	 edges	
and	therefore	not	visible.NATIVEThe	projector	 displays	the	current	 image	in	its	 true	 resolution	 when	the	incoming	 computer	
signal	has	a	lower	resolution	than	the	projector’s	native	resolution.
[Example 1]	When	 the	incoming	 sig-
nal	with	 the	resolution	 of	800	 ×	600	 is	
displayed	on	the	P420X/P350X:
[Example 2]	When	 the	incoming	 sig-
nal	with	 the	resolution	 of	800	 ×	600	 is	
displayed	on	the	P350W:
NOTE:
•	 When	a	non-computer	signal	is	displayed,	the	[NATIVE]	is	not	available.
•	 When	 a	signal 	with	 a	higher 	resolution 	than	 the	projector’s 	native 	resolution 	is	 displayed, 	[NATIVE]	
is	not	available.

•	 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.
Adjusting the Vertical Position of Image [POSITION] (not available on P350W)
