has	a	lower	or	higher	resolution	than	the	projector’s	native	resolution.	(→	page	2, 224)
When	the	incoming 	computer 	signal 	has 	a 	higher 	resolution 	than 	the 	projector's 	nativ e 	resolution, 	
the	center	of	an	image	will	be	displayed.
LETTER	BOXThe	image	of 	a 	letterbo x 	signal 	(16:9) 	is 	stretched 	equally 	in 	the 	hor izontal 	and 	v ertical 	directions 	
to	fit	the	screen.

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.
