Connecting to a Computer for Sound

If your computer presentation includes sound and you did not connect it to the projector's HDMI port, you can still play sound through the projector's speaker system (Pro L1100U/L1200U/L1300U). Just connect an optional 3.5 mm stereo mini-jack audio cable as described here.
Note: If your projector does not have an internal speaker system (Pro L1405U/L1500U/L1505U), you can play sound by connecting external speakers to the projector.
  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 or BNC port you are using.
    Note: If you are projecting video through the projector's DVI-D port, connect the end of your audio cable to the Audio3 port.
