In trying to answer your question . . .we do use the apps on our Samsumg smart TV, that is Netflix, Prime, You Tube, etc. Not sure if it supports eARC, but there is an HDMI cable that goes from the cable box to the TV. When watching these same apps on our projector, I would suppose they come from our Sony Blu-ray player! As I have said before, the TV and the projector are in the same room with the screen coming down from above by remote over and in front of the TV and using the same BOSE 321 speaker system for both TV and projector. We have no other room or speakers for utilizing a zone 2 HDMI from a possible new AV receiver, but if I did get one, I would need 2 HDMI outs for the TV and projector and hoping the same new SVS speakers would work for both! Hope this helps? Thanks!
