I am looking to buy a new sounder for use with my Samsung Frame 2019, Model: QE55LS03RAUXXU. As far as I can tell I will need to connect the sounder to the TV using an HDMI cable into the HDMI(ARC) port. however from what I have found on the internet for this the only connection in the One Connect box for this is an HDMI IN 3 (ARC).
Does this mean that there is no output for Dolby Atmos from this model?
@Rosseroony: I've had a look into this for you, and the QE55LS03RAUXXU is compatible with Dolby Digital+ with Atmos content, although it is only available via HDMI (ARC) for external devices that support the format. The HDMI IN 3 (ARC) port will meet your needs, however please ensure that your chosen soundbar supports Atmos.
