Connecting to a Computer for Sound

If your computer presentation includes sound and you did not connect it to the projector's USB-B 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.
