 Projecting an Image from an Angle (Geometric Correction Tool 
in Image Express Utility Lite)
 
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	171)	
•	 Your	correction	data	can	be	stored	in	the	projector	or	your	computer	which	can	be	restored	when	necessary.
•	Geometric	correction	can	be	used	when	connected	to	the	network	(by	wired	or	wireless	LAN)	or	by	video	cable.
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.

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.

  Using  the  Projector  to  Operate  Your  Computer  over  a  LAN 
(Desktop Control Utility 1.0)
Using	Desktop	 Control	Utility	1.0	allows	 you	to	remotely	 operate	your	computer	 placed	at	a	distance	 from	the	projector	
over	a	network	(wired	LAN	or	wireless	LAN).
What you can do with Desktop Control Utility 1.0
•	 A	commercially	available	USB	mouse	is	connected	to	the	projector	to	operate	the	computer.
•	 Suppose,	 for	example,	 a	PowerPoint	 file	to	be	 presented	 in	a	conference	 is	saved	 to	a	computer	 in	your	 office. 	
If	this	 computer	 is	connected	 to	the	 projector	 in	the	 conference	 room	with	LAN	 when	 the	conference	 is	held,	 the	
desktop	 screen	of	the	 computer	 in	your	 office	 (Windows	 7/Windows	 Vista/Windows	 XP)	can	be	projected	 and	the	
Power-Point	 file	can	 be	presented	 by	operating	 the	projector. 	In	 other	 words	 the	computer	 does	not	need	 to	be	
brought	into	the	conference	room.
IMPORTANT:
•	 You	 can	use	the	Desktop	 Control	Utility	1.0	to	operate	 a	computer	 located	in	a	separate	 room	from	the	projector	 over	a	network.	
Therefore,	 care	must	 be	exercised	 to	prevent	 any	third	 party	 from	viewing	 the	screen	 of	your	 computer	 (important	 documents),	
copying	files,	or	turning	off	the	power.
	 NEC	assumes	 no	liability	 for	any	 loss	 or	damages	 arising	from	information	 leak	or	system	 failure	while	you	are	using	 Desktop	
Control	Utility	1.0.
•	 This	 will	disconnect	 LAN	connection	 when	the	computer	 goes	in	the	 standby	 mode	while	the	Desktop	 Control	Utility	1.0	is	being	
used.
	 In	 the	Windows	 7/Windows	 Vista,	select	 [Control	 Panel]	→	[Hardware	 and	Sound]	→	[Power	 Options].	 Set	[Change	 when	the	
computer	sleeps]	to	[Never].	
	 In	the	Windows	 XP,	click	 [Control	 Panel]	→	[Performance	 and	Maintenance]	→	[Power	 Options]	→	[System	 Standby]	→	
[Never].
•	 The	screen	saver	function	is	off	while	Desktop	Control	Utility	1.0	is	running.
Connecting the projector to a LAN
Connect	 the	projector	 to	the	 LAN	 by	following	 the	instructions	 in	“Connecting	 to	a	Wired	 LAN”	(→	page	150),	 “Con-
necting	to	a	 Wireless	LAN” 	(→	page	151)	and	“9	Application	Menus	-	NETWORK	SETTINGS” 	(→	page	120)

Using the projector to operate your computer’s desktop screen
IMPORTANT:
•	 In	case	of	Windows	7/Windows	Vista,	disable	the	user	account	control	before	using	Desktop	Control	Utility	1.0.	
	 Windows	Vista	has	“User	 Account	 Control”	 function	to	protect	 the	computer.	 The	user	 account	 confirmation	 window	may	be	
displayed.	
	 Since	 Desktop	Control	 Utility	1.0	 cannot	 transfer	 the	user 	account 	confirmation 	window,	 this	window	 makes	the	 operation 	unavail-
able.	 Before	 using	Desktop	 Control	Utility	1.0,	it	is	 necessary	 to	disable	 the	user	 account	 control	of	Windows	 7/Windows	 Vista.	
After	logging	on	with	the	administrator	account,	follow	the	procedure	below	to	change	the	setting:
[Change Procedure]

1	 Click	[Control	Panel]	from	the	Start	Manu.
2	 Click	[User	Accounts	and	Family	Safety].
3	 Click	[User	Accounts].
4	 Click	[Change	User	Account	Control	settings].
5	 Change	[Choose	when	to	be	notified	about	changes	to	your	computer]	to	[Never	notify]	and	click	[OK].
•	 If	restarting	is	requested,	click	[Restart	now].

1	 Click	[Control	Panel]	from	the	Start	Menu. 	
2	 Click	[User	Accounts	and	Family	Safety].	
3	 Click	[User	Account].	
4	 Click	[Enable/Disable	User	Account	Control]. 	
5	 Remove	the 	checkmark 	for 	[Use 	User 	Account 	Control 	(UAC) 	to 	Help 	Computer 	Protection] 	and 	click	
[OK]. 	
•	 If	rebooting	is	requested,	click	[Reboot	Now]. 	
Upon	completion	of	Desktop	Control	Utility,	it	is	recommended	to	enable	the	user	account	control.
