❹ Projecting an Image from an Angle (Geometric Correction 
Tool in Image Express Utility Lite) (not supported by PE501X)
 
The	Geometric	 Correction	Tool	(GCT)	 function	 allows	you	to	correct	 distortion	 of	images	 projected	 even	from	an	
angle. 	
What you can do with GCT
•	 The	GCT	feature	includes	the	following	three	functions
•	4-point	 Correction:	You 	can 	fit 	a 	projected 	image 	within 	the 	border 	of 	the 	screen 	easily 	by 	align 	the 	four 	corners	
of	an	image	to	the	ones	of	the	screen.
•	Multi-point	 Correction:	You	 can	correct	 a	distorted	 image	on	the	 corner	 of	a	wall	 or	irregular	 shaped	screen	
by	using	many	separated	screens	to	correct	the	image	as	well	as	4-point	Correction.
•	Parameters Correction:	You	 can	correct	 a	distorted	 image	by	using	 a	combination	 of	transformational	 rules	
prepared	in	advance.
This	section	will	show	an	example	for	use	with	4-point	Correction.
For	information	 about	“Multi-point	 Correction”	and	 “Parameters	 Correction”,	see	the	help	 file	of	Image	 Express	
Utility	Lite. 	(→	page	177, 179)	
•	 Your	correction	data	can	be	stored	in	the	projector	or	your	computer	which	can	be	restored	when	necessary.
•	 The	GCT	function	is	available	with	a	USB	cable,	wired	or	wireless	LAN	connection,	and	video	cable. 	
Projecting an Image from an Angle (GCT)
This	section	 will	show	 an	example	 for	use	 with	 USB	 Display	 (using	a	USB	 cable	 to	connect	 a	computer	 and	the	pro-
jector).
•	 The	USB	Display	function	will	automatically	display	the	control	window	
•	 For	 a	video	 cable	or	LAN	 connection,	 install	and	start	 Image	 Express	 Utility	Lite	in	your	 computer	 beforehand. 	(→ 
page	173)
Preparation: 	Adjust	the	projector	position	or	the	zoom	so	that	the	projected	image	can	cover	the	whole	screen	area.
1.	 Click	the	 “		”	(Picture)	icon	and	then	the	 “		”	button.
	 The	 “4-point	Correction” 	window	will	be	displayed.
2.	 Click	the	“Start	Correction” 	button	and	then	“Start	4-point	Correction” 	button.
 A green frame and a mouse pointer (  ) will be displayed.
•	 Four	[	•	]	marks	will	be	appeared	at	four	corners	of	the	green	frame

3.	 Use	the	mouse	to	click	the	[	•	]	mark	of	which	corner	you	wish	to	move.
 The currently selected [ •	]	mark	will	turn	red.
(In	the	above	example,	 Windows	screens	are	omitted	for	clarification.)
4.	 Drag	the	selected	[	•	]	mark	to	the	point	you	wish	to	correct	and	drop	it.
•	 When	you	click	 somewhere	 within	the	project	 image	area,	the	nearest	 [	•	]	 mark	 will	go	to	the	 position	 where	
the mouse cursor is.
5.	 Repeat	Step	3	and	4	to	correct	the	distortion	of	the	projected	image.
6.	 After	completing, 	right-click	the	mouse.
 The green frame and the mouse pointer will disappear from the projected image area. This will complete the cor-
rection.
7.	 Click	the	 “X”	(close)	button	on	the	 “4-point	Correction”	window.
	 The	“4-point	Correction” 	window	will	disappear	and	the	4-point	correction	will	take	effect.
8.	 Click	the	“		”	button	on	the	control	window	to	exit	the	GCT.
TIP:
•	 After	 performing	 the	4-point	 correction,	 you	can	save	 the	4-point	 correction	 data	to	the	 projector	 by	clicking	 “File”	→	“Export	 to	
the	projector…”	on	the	“4-point	Correction”	window.
•	 See	the	Help	 of	Image	 Express	 Utility	Lite	for	operating	 “4-point	Correction”	 window	and	other	 functions	 than	GCT.	 (→	page	177,

❺ Projecting Images from the Projector over a LAN (Image 
Express Utility 2.0) (not supported by PE501X)
What you can do with Image Express Utility 2.0
•	 Using	Image	Express	 Utility	2.0	allows	 you	to	send	 the	screens	 of	your	 computers	 to	the	 projector	 via	wired/wire-
less	LAN.
	 The	 difference	 from	Image	 Express	 Utility	Lite	is	that	 projected	 images	can	be	sent	 from	 a	computer	 to	not	 only	
one	projector	but	also	to	two	or	more	projectors	at	the	same	time.
	 When	 “Meeting	Mode” 	is	used,	projected	images	can	be	sent	and	received	between	two	or	more	computers.
•	 High-speed, 	high-quality	image	transmissions	based	on	NEC’s	original	compression	algorithm
	 NEC’s	original	compression	 algorithm	allows	high-quality	 images	to	be	 sent	 over	 the	network	 at	high	 speed,	 from	
your	computer	to	the	projector.
•	 Simultaneous	projection	by	multiple	projectors
	 Images	 can	be	sent	 from	 a	computer	 to	not	 only	 one	projector	 but	also	 to	two	 or	more	 projectors	 at	the	 same	
time.
•	 “Easy	Connection” 	function	for	connecting	wireless	LAN
	 By	using	“Easy	Connection” 	function*1,	the	complicated	setting	of	wireless	LAN	can	be	simplified.
*1	 This	function	 can	be	used	 when	 Windows	 XP	is	used	 as	the	 OS	 and	 when	 you	have	 a	“Computer	 Adminis-
trator”	privilege. 	If	 the	 OS	 is	Windows	 7/Windows	 Vista,	input	of	logon	 password	 as	“Administrator” 	may	 be	
prompted.

•	 Projected	images	can	be	transferred	and	saved	to	computers.
	 When	“Meeting	Mode”	is	 used,	 projected	 images	can	be	sent	 to	the	 computers	 of	all	 the	 participants	 (attendants)	
of	a	“Meeting”. 	The	received	images	can	be	saved	to	your	computer	with	a	memo	(text	data)	attached.

	 When	
switching	to	another	 presenter	 during	the	conference,	 the	participants	 (attendants)	 can	simply	 click	a	button	
to	switch	over	to	the	new	presenter.
•	 Central	management	of	the	projecting	computer
	 Using	 the	Training	 Mode	allows	 you	to	use	 a	single	 computer	 (Manager)	 to	manage	 which	computer	 (Attendant)	
projects.	Possible	 operation	 includes	switching	 projecting	 computers	 to	project	 from,	as	well	 as	temporarily	 termi-
nating	communication	with	the	projector.
