 Use  this  port  to  connect  your  PC  or  control  system 
to  control  your  projector  via  a  serial  cable.  This 
enables  you  to  control  the  projector  using  serial 
communication  protocol.  A  commercially  available 
RS232C cross cable is required to use this port. You 
can  also  control  the  projector  by  using  PC  Control 
Utility  3.0  contained  on  the  supplied  User  Support-
ware  5  CD-ROM.  To  do  so  you  must  first  have  PC 
Control  Utility  3.0  installed  on  your  PC.  If  you  are 
writing  your  own  program,  typical  PC  control  codes 
are on page 141.

2. Installation and Connections
 Making Connections
Connecting Your PC or Macintosh Computer
NOTE: When using with a notebook PC, be sure to connect the projector and notebook PC while the projector is in standby mode 
and before turning on the power to the notebook PC.
In most cases the output signal from the notebook PC is not turned on un\
less connected to the projector before being powered up.
*  If the screen goes blank while using your remote control, it may be the result of the computer’s screen-saver or power manage-
ment software.
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 e\
nable/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.
iBM V ga  or Compatibles ( n otebook 
type) or Macintosh ( n otebook type)
NOTE: The COMPUTER 1 IN and COMPUTER 2 
IN connectors support Plug & Play (DDC2B).
NOTE:  For  older  Macintosh,  use  a  commercially 
available  pin  adapter  (not  supplied)  to  connect  to 
your Mac’s video port.
•  First turn off the computer and the projector before making connections.\
•   Turn  down  the  volume  on  the  computer  before  connecting  an  audio  cable  to  the  headphone  jack  of  the  com
-
puter.  After  connecting  the  computer  to  the  projector,  you  can  adjust  the  sound  level  on  the  computer  and  the 
projector to your preference.
•
 
You are recommended to connect an audio cable to an audio out connector \
(mini jack type) if any.
NOTE: The NP905/NP901W is not compatible with video decoded outputs of either \
the NEC ISS-6020 or ISS-6010 switchers.

2. Installation and Connections
NOTE: An image may not be displayed correctly when a Video or S-Video source 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 following.
*
  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 on the remote control or the AUTO ADJUST button on 
the projector cabinet.
•
  If  you  have  a  PC  with  a  DVI  output,  use  a  commercially  available  DVI-to-HDMI  cable  to  connect  the  PC  to  the 
HDMI  IN  connector  of  the  projector.  Only  the  digital  signal  is  available.  Connect  the  AUDIO  output  of  the  PC 
to  the  COMPUTER/COMPONENT  2  AUDIO  IN  stereo  mini  jack,  and  in  the  menu  select  [HDMI  SETTINGS] → 
[AUDIO SELECT] → [COMPUTER 2]. (→ page 116)

pen, restart your PC.
•
 
Some  graphics  cards  have  both  analog  RGB  (15-pin  D-Sub)  and  DVI(or  DFP  outputs.  Use  of  the  15-pin  D-Sub  connector  may 
result in no picture being displayed from the digital output of the grap\
hics card. 
•
 
Do not disconnect the DVI-to-HDMI cable while the projector is running. If the signal cable has been disconnected and then re
-
connected, an image may not be correctly displayed. Should this happen, \
restart your PC.
•
 
The HDMI IN connector accepts VGA (640 x 480), SVGA (800 x 600), XGA (1024 x 768), 1152 x 864, SXGA (1280 x 1024 @ up

2. Installation and Connections
Connecting an External Monitor
You can connect a separate, external monitor to your projector to simultaneously view on a monitor the RGB analog 
or component image you’re projecting.
NOTE:
•  Daisy chain connection is not possible.
•
  The MONITOR OUT connector will not output video and sound (Digital sign\
al) via the HDMI IN connector.
•
  When audio equipment is connected, the projector speaker is disabled.
•
  When [NORMAL] is selected from [STANDBY MODE], the MONITOR OUT connector outputs the last displayed video signal and 
the AUDIO OUT jack outputs the last audio signal. The sound level remain\
s the same as the last one.
•
 
Selecting  [POWER-SAVING]  in  [STANDBY  MODE]  stops  outputting  a  video  signal  from  the  MONITOR  OUT  connector  during 
standby mode. This causes the AUDIO OUT jack to stop outputting sound.

What is  h DC p / h DC p  technology?
HDCP  is  an  acronym  for  High-bandwidth  Digital  Content  Protection.  High  bandwidth  Digital  Content  Protection 
(HDCP) is a system for preventing illegal copying of video data sent o\
ver a Digital Visual Interface (DVI).
If you are unable to view material via the HDMI input, this does not necessarily mean the projector is not functioning 
properly.  With  the  implementation  of  HDCP,  there  may  be  cases  in  which  certain  content  is  protected  with  HDCP 
and might not be displayed due to the decision/intention of the HDCP com\
munity (Digital Content Protection, LLC).
