I just bought a BENQ HT3550 and need to hook up my Marantz Atmos rcvr. I have an ARC output on my Marantz but my new projector just has two 2.1 hdmi hdcp 2.2 ports. If I connect a high speed optical hdmi to one of these and use t,he other for my Fire Tv Cube will I get Atmos sound? Do I still connect to the ARC output hdmi monitor 1 output or to monitor 2 hdmi output or do I have to run two high speed hdmi cables and bring one back from the projector to an hdmi input on the rcvr? This is driving me crazy trying to find an answer as I currently have an 11.2 Atmos setup with ceiling speakers and it’s awesome so I want to make Atmos work on my new projector. Thanks a bunch if someone can help!
