1. INTRODUCTION
Introduction to the VT650 Projector
This section introduces you to your new VT650 Projector and
describes the features and controls.
Congratulations on Your Purchase of The VT650 Projector
The VT650 is one of the very best projectors available today.
The VT650 enables you to project precise images up to 300 inches
across (measured diagonally) from your PC or Macintosh com-
puter (desktop or notebook), VCR, DVD player, document cam-
era, or even a laser disc player.
You can use the projector on a tabletop or cart, you can use the
projector to project images from behind the screen, and the pro-
jector can be permanently mounted on a ceiling*
1. The remote
control can be used wirelessly.
Features you’ll enjoy:
•Simple set up and operation.
•A high-performance 160 watt (130 watt in Eco mode) NSH
lamp.
•The lamp life can be extended up to 3000 hours by using
the Eco mode.
•The supplied wireless remote control that operates the pro-
jector from any angle.
•Manual zoom control enables you to adjust the image be-
tween 25 (0.63 m) and 300 inches (7.6 m) (measured di-
agonally).
•Keystone correction allows you to correct trapezoidal dis-
tortion so that the image is square.
•Color Management feature includes Gamma Correction,
White Balance, and Color Correction that provides natural
and true color reproduction.
•An image can be projected from in front or behind a screen,
and the projector can even be installed on the ceiling.
•NEC Technologies’ exclusive Advanced AccuBlend intel-
ligent pixel blending technology - an extremely accurate
image compression technology - offers a crisp image with
UXGA (1600 
 1200) resolution*
2.
•Supports most IBM VGA, SVGA, XGA, SXGA*2,
UXGA*2, Macintosh, component signal (YCbCr / YPbPr)
or any other RGB signals within a horizontal frequency
range of 15 to 100 kHz and a vertical frequency range of 50
to 120 Hz. This includes NTSC, PAL, PAL-M, PAL-N,
PAL60, SECAM and NTSC4.43 standard video signals.
NOTE: Composite video standards are as follows:
NTSC: U.S. TV standard for video in U.S. and Canada.
PAL: TV standard used in Western Europe.
PAL-M: TV standard used in Brazil.
PAL-N: TV standard used in Argentina, Paraguay and Uruguay.
PAL60: TV standard used for NTSC playback on PAL TVs.
SECAM: TV standard used in France and Eastern Europe.
NTSC4.43: TV standard used in Middle East countries.•You can use the supplied wireless remote control and re-
mote mouse receiver to operate your PC mouse wirelessly
from across the room.
The remote mouse receiver supports almost any PC using a
USB connection or the supplied USB-to-PS/2 adapter.
•You can control the projector with a PC using the PC Con-
trol port.
•The contemporary cabinet design is light, compact, easy to
carry, and complements any office, boardroom or audito-
rium.
*1Do not attempt to mount the projector on a ceiling your-
self.  The projector must be installed by qualified techni-
cians in order to ensure proper operation and reduce the risk
of bodily injury.  In addition, the ceiling must be strong
enough to support the projector and the installation must be
in accordance with any local building codes.  Please consult
your dealer for more information.
*2 An SXGA image (1280
1024) and a UXGA (1600
1200)
image are converted into an 1024
768 crisp image with
NEC technology’s Advanced AccuBlend.
Getting Started
The fastest way to get started is to take your time and do every-
thing right the first time. Take a few minutes now to review the
user’s manual. This may save you time later on. At the begin-
ning of each section of the manual you’ll find an overview. If the
section doesn’t apply, you can skip it.
