Connecting to a Computer for Sound

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