Audio speaker mounting in portrait orientation (optional)
When the IDS display is mounted in portrait mode, relocate the top-right side speaker to the lower-left side to have better natural stereo

1. Remove the mounting screw of the speaker and slide the speaker downward to disengage the mounting hooks. Pull the
speaker downward enough so the cable connector is exposed and disengage the connector.
