Connecting to a Computer for Sound

If your computer presentation includes sound and you did not connect it using the projector's HDMI port, you can still play sound through the projector's speaker system. Connect an optional stereo mini-jack adapter cable (with one 3.5 mm mini-plug and two RCA plugs).
  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 projector's Audio ports.
