Connecting
Before connecting
f Before connecting, carefully read the operating instructions for the external device to be connected.
f Turn off the power of all devices before connecting cables.
f Connect cables taking care of the following descriptions. Failure to do so may result in malfunctions.
g When connecting a cable to a device connected to the projector or the projector itself, touch any nearby
metallic objects to eliminate static electricity from your body before performing work.
g Do not use unnecessarily long cables to connect a device to the projector or to the projector body. The longer
the cable, the more susceptible to noise it becomes. Since using a cable while it is wound makes it act like an
antenna, it is more susceptible to noise.
g When connecting cables, connect GND first, then insert the connecting terminal of the connecting device in a
straight manner.
f Acquire any connection cable necessary to connect the external device to the system that is neither supplied
with the device nor available as an option.
f If synchronization signals output from computers or video equipment are disrupted due to changes in the video
output setting or other reasons, colors of projected images may be temporarily disrupted.
f For the connection when linking multiple projectors and using the contrast synchronization function and the
shutter synchronization function, refer to "Connecting example when using the contrast synchronization function/
shutter synchronization function" (x page 51).
f Some computer models or graphic cards are not compatible with the projector.
f Connect using an extension device, etc., when installing the projector away from the video equipment. The
projector may not display the image properly when it is connected directly using a long cable.
f For details of the types of image signals that can be used with the projector, refer to "List of compatible signals"
(x page 268).
Connecting example: AV equipment
For <HDMI IN 1>/<HDMI IN 2> terminals
Note
f Switching of the setting in the [DISPLAY OPTION] menu → [HDMI IN] → [HDMI1] / [HDMI2] → [EDID SELECT] may be required depending
on the connected external device when HDMI signal is input.
f For the HDMI cable, use an HDMI High Speed cable that conforms to the HDMI standards. However, when the following 4K image signal
exceeding the supported transmission speed of the HDMI High Speed cable is to be input, use the HDMI cable supporting the high speed
transmission of 18 Gbps such as the one with Premium HDMI cable authentication.
g An image signal with high specification color depth and gradation such as 3840 x 2160/60p 4:2:2/36-bit or 3840 x 2160/60p 4:4:4/24-bit
Images may be disrupted or may not be projected when an image signal exceeding the supported transmission speed of the HDMI cable is
input.
f The <HDMI IN 1> / <HDMI IN 2> terminals of the projector can be connected to an external device equipped with a DVI-D terminal using an
HDMI/DVI conversion cable. However, this may not function properly for some external devices, and images may not be projected.
