greatly. The projector must be used at temperatures
between 32°F (0°C) and 95°F (35°C).
•Do not expose the projector to moisture, dust, or
smoke. This will harm the screen image.

•Ensure that you have adequate ventilation around your
projector so heat can dissipate. Do not cover the vents
on the side of the projector.
Reflecting the Image
Using a mirror to reflect your projectors image enables
you to enjoy a much larger image. Contact your NEC
dealer if you need a mirror. If youre using a mirror and
your image is inverted, use the MENU and SELECT
buttons on your projector cabinet or your remote control
to correct the orientation. See page 86.

2. Installation and Connections
 Making Connections
NOTE: When using with a notebook PC, be sure to connect between the projector and the notebook PC before turning on the
power to the notebook PC. In most cases signal cannot be output from RGB output unless the notebook PC is turned on after
connecting with the projector.
*If the screen goes blank while using your remote control, it may be the result of the computers screen-saver or power
management software.
*If you accidentally hit the POWER button on the remote control, wait 60 seconds and then press the POWER button again to
resume.

IBM VGA or Compatibles (Notebook
type) or Macintosh (Notebook type)
Connecting your PC or Macintosh computer to your projector will enable you to project your computers screen image
for an impressive presentation.
To connect to a PC or Macintosh, simply:
1. Turn off the power to your projector and computer.
2. Use the supplied signal cable to connect your PC or Macintosh to the projector.
3. Connect the supplied power cable. See page 28.
4. Turn on the projector and the computer.
5. If the projector goes blank after a period of inactivity, it may be caused by a screen saver installed on the computer
youve connected to the projector.
NOTE: The COMPUTER 1 connector
supports Plug & Play (DDC2).
Enabling the computer’s external display
Displaying an image on the notebook PC’s screen does not necessarily mean it outputs a signal to the projector.
When using a PC compatible laptop, a combination of function keys will enable/disable the external display.
Usually, the combination of the ‘Fn” key along with one of the 12 function keys gets the external display to come on
or off. For example, NEC laptops use Fn + F3, while Dell laptops use Fn + F8 key combinations to toggle through
external display selections. 
						

							24
NOTE: The 8768 is not compatible with video decoded outputs of  sp eci al ISS-6020 and ISS-6010 switchers.
NOTE: An image may not be displayed correctly when a Video or S-Video so\
ur ce is played back via a commercially available scan
converter .
This is because the projector will process a video signal as a computer \
signal at the default setting. In that case, do the fol lowing.
* When an image is displayed with the lower and upper black portion of the\
 screen or a dark image is not displayed correctly:
Project an image to fill the screen and then press the AUTO ADJ button o\
n the remote control or the AUTO ADJUST button onthe projector cabinet.
* When noise appears on the sides of the screen:
Use the Overscan featur e to display the image correctly .
Be sur e to change the Overscan to 0% before pr essing the AUTO ADJ or AUTO ADJUST button, other wise an image may be
displayed with its sides cut off.
