If
your external speakers or A/V receiver are HDMI ARC-compatible, you
can connect them to the projector's HDMI2 (ARC) port using an optional HDMI
cable.
In the projector's Settings menu, make sure the HDMI CEC setting is enabled and then enable HDMI2 ARC. In the projector's Sound menu, set Sound Output as ARC/Optical (PCM) or ARC/Optical (Auto) in Other Than HDMI3 (Game).
Note: The
projector's speakers are disabled when audio is output to a device
connected to the HDMI2 (ARC)
port. If you want to output higher quality audio, set Sound Output as ARC/Optical (Auto) in the projector's Sound
menu.
- Remove the projector's side cover, if necessary.
- Connect the HDMI cable to
the ARC-compatible HDMI port on your external speakers or A/V
receiver.
Note: To display signals in the 18 Gbps transmission band, such as from a 4K 60 fps source, use a cable rated for HDMI 2.0 or higher or you may have trouble displaying an image.
- Connect the other end to the HDMI2 (ARC) port on the rear of the projector.
- Select any HDMI control settings on the connected speakers or receiver, as necessary. See your device's documentation for more information.
- Carefully replace the
projector's side cover.
Note: The projector's side cover can be split into two parts to allow more space for connected streaming devices and cables. See the link below.
Note: The
audio format that is output from the projector's HDMI2 (ARC) port varies depending on the
input source. When the input source is HDMI, audio is output up to
5.1 ch (AC-3 or DTS). When playing Android TV content, audio is
output in 2 ch (PCM). You cannot output sound from the HDMI2 (ARC) port when the input source is
HDMI3 (Game).
