Note: To connect a Mac that includes only a Mini DisplayPort, Thunderbolt port, or Mini-DVI port for
video output, you need to obtain an adapter that allows you to connect to the projector's HDMI port.
Contact Apple for compatible adapter options. Older Mac computers (2009 and earlier) may not support
audio through the
HDMI port.
1. Connect the HDMI cable to your computer's HDMI output port.
2. Connect the other end to one of the projector's HDMI ports.
Note: The projector converts the digital audio signal sent from your computer into a mono analog signal
for the internal speaker or a stereo analog signal if you are connecting to external speakers. (Make sure
the HDMI audio playback device on your computer's audio settings is set to
EPSON PJ .)
Note: If you have problems hearing audio through the HDMI connection, you can use one of the
projector's audio ports instead to play sound. Connect one end of an optional 3.5 mm stereo mini-jack
audio cable to one of the projector's audio ports and the other end to your computer's audio out port.
Then select the audio port you connected to as the
HDMI1 Audio Output , HDMI2 Audio Output or
HDMI3 Audio Output setting in the Signal I/O menu.
