How do I play sound through my product?
If your computer or video equipment is connected to the projector's Computer or Video port, you will need to connect a separate cable to the Audio port to play sound. See Connecting to a Computer for Sound or Connecting to a Video Source for Sound for details.
If you connect using an HDMI cable (PowerLite 1750/1760W/1770W/1775W only) or use the USB Display function, the video and sound are both transferred and you won't need to connect any additional cables for audio.
