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 IN or HDMI 2 IN connector (only digital video
signals can be input). Also, connect the computer's audio output to the projector's audio input
connector. In this case, switch the HDMI1 or HDMI2 setting at on-screen menu's audio selection
on the projector to [COMPUTER]. (→ page 150)
To connect the computer's DVI output connector to the projector's DisplayPort input connector,
use a commercially available converter.
NOTE:
• Turn off the power of the computer and projector before connecting.
• When connecting the headphone terminal of the computer to the audio input terminal of the projector with an audio cable, set
the computer volume to a low level before connecting. Then adjust the volume of the projector and the volume of the computer
alternately to set the volume to a suitable 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 recon-
nected, an image may not be correctly displayed. Should this happen, restart your PC.
• The COMPUTER IN video input connectors 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.
