Cautions when using a DVI signal
• When the computer has a DVI output connector, use a commercially available converter cable to connect the computer to 
the projector’s HDMI 1 or HDMI 2 input connector (only digital video signa\
ls can be input). Also, connect the computer’s audio 
output to the projector’s BNC audio input connector. In this case, switch the HDMI1 o\
r HDMI2 setting at on-screen menu’s 
audio selection on the projector to [BNC]. (→ page 125)
  To connect the computer’s DVI output connector to the projector’s DisplayPort input connector, use a commercially available 
converter.

NOTE: When Viewing a DVI Digital Signal
•  Turn off the power of the computer and projector before connecting.
•  Lower the computer’s volume setting before connecting an audio cable to the headphones connector. When using with a computer connected to the projector, adjust 
the volume of both the projector and computer to set the appropriate volume level.
•  If the computer has a mini-jack type audio output connector, we recommend connecting the audio cable to that connector.
•  When a video deck is connected via a scan converter, etc., the display may not be correct during fast-forwarding and rewinding.
•  Use a DVI-to-HDMI cable compliant with DDWG (Digital Display Working Group) DVI (Digital Visual Interface) revision 1.0 standard. The cable should be within 197"/5 
m long.
•  Turn off the projector and the PC before connecting the DVI-to-HDMI cable.
•  To project a DVI digital signal: Connect the cables, turn the projector on, then select the HDMI input. Finally, turn on your PC.
  Failure to do so may not activate the digital output of the graphics card resulting in no picture being displayed. Should this happen, 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 graphics card.
•  Do not disconnect the DVI-to-HDMI cable while the projector is running. If the signal cable has been disconnected and then reconnected, an image may not be correctly 
displayed. Should this happen, restart your PC.
•  The COMPUTER video input connectors support Windows Plug and Play. The BNC video input connector does not support Windows Plug and Play.
•  A Mac signal adapter (commercially available) may be required to connect a Mac computer.
  To connect a Mac computer equipped with a Mini DisplayPort to the projector, use a commercially available Mini DisplayPort → DisplayPort converter cable.

Connecting an External Monitor
You can connect a separate, external monitor to your projector to simultaneously view on a monitor the computer analog image 
you’re projecting.
• Please refer to Page 65 when displaying the [PIP/PICTURE BY PICTURE] screen.
NOTE:
•  When outputting HDMI signals, turn on the power of the video device on the output side and keep it connected before inputting video signals into this device. The 
HDMI output terminals of the projector are equipped with repeater functions. When a device is connected to the HDMI output terminal, the resolution of the output 
signal is limited by the resolution supported by the connected device.
•  Connecting and disconnecting an HDMI cable or selecting another input source on the second and subsequent projectors will disable the HDMI repeater function.
•  In the case of the HDMI output terminal of the projector, the theoretical number of units that can be connected in a series is seven. The maximum number of units 
that can be connected may be reduced by the external environment and quality of the signal and cable, etc. The number of units that can be connected may differ 
depending on the HDCP version, restriction on the number of HDCP repeaters in the source device and the quality of the cable. The overall system needs to be checked 
in advance when building a system.
•  When audio equipment is connected, the projector speaker is disabled.
•  To output audio from the audio output terminal when the input terminal is neither “COMPUTER IN” nor “BNC IN”, select [BNC] under [AUDIO SELECT] of the on-screen 
menu.
•  When the [STANDBY MODE] is set to [NORMAL], video and audio will not be output when the projector is set to the standby mode. Set the standby mode to [NETWORK 
STANDBY] .
•  Both the composite video signal from each input connector as the computer, BNC, and BNC (CV), and the S-video signal from the BNC (Y/C) Input connector are not 
output from HDMI OUT Connector of this projector.

Portrait projection (vertical orientation)
Portrait screens from a computer can be projected by installing the projector in 
a vertical orientation. All the screens such as the on-screen menu will be rotated 
in an counter-clockwise direction.
The projector is equipped with a sensor to automatically detect the installati\
on 
state.
When the projector is installed in a portrait configuration for the first time with 
the lamp lit up, a caution message to indicate that the operating time o\
f the 
lamp may be shortened will be displayed.
This message will automatically disappear when the installation state of the 
projector is returned to the original state.
 Precautions during installation
• Please do not install the projector in a vertical orientation on top of the floor or table on its own. The intake ve\
nt may be 
obstructed, resulting in the projector getting warm and the possibility of fire and malfunction occurring.
•  For vertical installation, install the projector with the intake vent (filter) facing downwards. A stand for supporting the 
projector needs to be made for this purpose. In this case, the stand must be designed such that the center of gravity of 
the projector is located well within the legs of the stand. If not, the projector may fall over and result in injury, damage 
and malfunction.
•  Do not use the lens shift function when performing portrait projection. Use the position of the lens shift mechanism in 
the center (lens center).
NOTE:
•  The lamp replacement time (as a guide)* is about 2000 hours for portrait projection.
* Replacement time is not guaranteed.
•  When installing in a portrait configuration for the first time, portrait projection cannot be used when the number of lamp hours used shown under [INFO.] → [USAGE 
TIME] → [LAMP HOURS USED] in the on-screen menu exceeds 1900 hours.
•  When the [FAN MODE] is set to a mode other than [AUTO], portrait projection cannot be used.
Design and manufacturing conditions for the stand
Please engage an installation service provider for the design and manufacture of the customized stand to be used for portrait 
projection. Please ensure that the following are complied with when designing the stand.
1.  Maintain an opening of at least 310 × 170 mm so as not to obstruct th\
e intake vent / filter of the projector.
2.  Maintain a distance of at least 130 mm between the projector intake vent and the floor (for the opening of the filter cover).
3.  Use the four screw holes at the back of the projector to secure it to the stand.
  Screw hole center dimension: 200 × 250 mm
  Screw hole dimension on the projector: M4 with a maximum depth of 8 mm.
* Please design the stand such that the rear legs at the back of the projector do not contact the stand. The front legs can 
be turned and removed.
4.  Horizontal adjustment mechanism (for example, bolts and nuts in four locations)
5.  Please design the stand such that it does not topple over easily.
