What sources play Dolby Atmos
content?
The sound bar is in a room with a
vaulted ceiling. Will I hear all the
sounds properly?
The system information say the
audio type is Dolby Atmos-Dolby
Digital Plus or Dolby Atmos-TrueHD.
How do I get one or the other?
•
Dolby Atmos content can be found on select streaming apps, on 4K UHD Blu-Ray discs, and on
some gaming systems and streaming sticks. To play Atmos content from these devices, connect
the device directly to the HDMI in port of the sound bar.
•
Dolby Atmos supported streaming apps built into to connected TVs may also be played on the
HDMI ARC port.
•
SmartCast Mobile App, Bluetooth, USB, Aux, Optical and Digital Coax inputs do not support Dolby
Atmos.
•
To clearly hear all Atmos has to offer, you will need a flat ceiling that is between 2.2 and 3.6
meters high. This allows the height speakers to reflect off the ceiling providing the sounds that
would come from above.
•
Vaulted ceilings or ceilings with acoustic treatments or tiles will diminish the effect. From the
remote control select Height --> Virtual for a virtualized height experience. Dolby Atmos content
will be played in Dolby Digital Plus format in this mode.
•
Dolby Atmos-TrueHD typically comes from a UHD Blu-Ray player or console that is plugged into
the sound bar’s HDMI IN port. Dolby Atmos-Dolby Digital Plus is typically sent from supported
apps being played from a smart TV that is plugged into the sound bar's HDMI ARC port.
How do I know if I'm playing Dolby
Atmos content?
•
You can verify content via the SmartCast Mobile App. Download the SmartCast Mobile App and
sync your sound bar. Go to Settings >System Information to see what type of audio is being
played. Visit VIZIO.com/Setup for more on the SmartCast Mobile App.
•
When Dolby Atmos content is detected the audio format LED on the bar will briefly appear green.
•
From the remote control, choose the Info menu option and press the Play/Pause key. The sound
bar will announce the current input and audio format being played.
