Connecting to a Computer for Sound

If your computer presentation includes sound and you did not connect it to the projector's USB TypeB or HDMI port, you can still play sound through the projector's speaker system. Just connect an optional 3.5 mm stereo mini-jack audio cable as described here.
  1. Connect the audio cable to your laptop's headphone or audio-out jack, or your desktop's speaker or audio-out port.
  2. Connect the other end to the Audio port that corresponds to the Computer port you are using.
