Yes sound bar has one HDMI input and one HDMI output. I have a shield and TiVo Edge, both which are atmos capable. My TV is old does not have CEC nor Arc. I was going to plug TiVo directly into Soundbar hdmi in and Soundbar HDMI out of Soundbar into TV to get picture.your 1080p tv may not be atmos capable. you could probably stick an atmos capable streaming stick into your soundbar and go from there. im assuming the soundbar has hdmi inputs.
i was about to post exactly the same comments, while they may be very good sounding soundbars, and they may contain reflecting Atmos (which IMNSHO is barely noticeable as an improvement to discrete channels) their Atmos implementation isn't worth worrying about, especially in the 1080p world.While it may be better than nothing, soundbars and headphones can not deliver true immersive audio. Whether it is a question of Dolby Atmos, DTS:X, or Auro3D, you can not hope to achieve the desired three-dimensional effect without overhead speakers. Even the specially designed Dolby Atmos Enabled (DAE) speakers that "bounce" sound off the ceiling are a compromise that can only work well in limited circumstances.
I would set my expectations low regarding Atmos reproduction from that soundbar and would not base my purchase on that one feature.
