Using Basic Projector Features
If your computer has an HDMI port, you can connect it to the projector using an HDMI cable and send the computer's audio with the projected image.
To connect a Mac that does not have an HDMI port, you need 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.
Connect the HDMI cable to your computer's HDMI output port.
Connect the other end to the projector's HDMI port.
If you have problems hearing audio through the HDMI connection, connect one end of a commercially available 3.5 mm stereo mini-jack audio cable to the projector's Audio port and the other end to your computer's audio out port. Select the audio input port you connected to in the projector's Extended menu. (PowerLite 994F)
