I just installed the new Fios+ services, including the VMS 4100 ATV and two new setup boxes. Really no trouble with the installation, found it very easy. My question: will my streaming apps - Netflix, Prime, etc. show my content in 4K? I have a 4K TV and pay extra for the Netflix 4K service for example. I'm curious whether what I'm watching will be in 4K or not (haven't spent any time looking at it yet). One other question - I was sent one extra set top box and remote which I don't need. Should I return that? I don't think I'm being charged for it.
