A lot of folks with new 4k HDTVs forget about this step. Only the ‘premium’ level can receive 4K.
I have a new 55 inch Roku TCL 4k HDR TV that is wired directly via ethernet. My isp is Comcast and I have 175mbps down and 11mbps up speeds at 10 miliseconds. A direct speed test at the point my ethernet cable enters the port on the TV is 175mbps +. However I canceled my Netflix 4k programming because I was still only receiving 1080 p.
I have updated my tv software, reset the tv, set Netflix streaming to " High"...My "secret menu" TCL internet speeds are set to automatic. I have even reinstalled the Netflix app. All Netflix connection tests consistently return varied results from 14 to 18 mbps and are usually accompanied by varied "nw" codes. I have spent over an hour with Netflix CS doing all the little silly things they read off of the little index cards in front of them. They have not been able to help in any way.
Speed test results from my other apps ( Amazon etc ) all reflect 150 to 170mbps results and the 4k programming is stunning while of course Netflix is terrible. Comcast has verified my speeds and has indicated that the Netflix servers are the problem... Again, Netflix does not have a clue.. I suspect that Netflix 4k is nothing more than a scam in which they hope the 4k upconverting feature of our tvs will pass for 4k.. Can anyone offer any insight as to this problem ? I am at a loss...even my laptop wireless speeds are breaking 160mbps..... direct or wireless seems to make no difference what so ever...
