A proper lossless 4k/Atmos stream is 85 Mb/s - 128 Mb/s, which is 85 - 128mbps.
100mbps doesn't fit the bill, to stream 4k you need a 1gbps Ethernet connection.
I have already spoke to Samsung about this, even their latest and most expensive TV models only have a 100mbps connection yet they deliver 4k TV's, Atmos/DTS:X speaker sets.
They advised me to purchase their Samsung UBD-M9500 or UBD-M9700 player to fix this problem because they should have a 1gbps, turns out even these players have a 100mbps connection.
Sony and LG are doing the same as Samsung.
Why sell 4k TV's and Atmos/DTS:X speaker sets without offering a product that can actually play the content without inserting a disc, now I have to start researching 3rd party products to be able to make use of these features.
