I have a Samsung 65" TU700d. Besides when I change channels (DirecTV Streaming), the picture takes anywhere from 30 seconds to a couple of minutes to clear up, sometimes never. When I go to the 'watch now' section I click on about 4 then it starts over when there's about 10 to see. I have an expander on the North side of the living room, the TV is hard wired to it, the expander is hard wired to the router on the South side of the living room and it is hard wired to the ATT modem. I have fiber optic at 1 gb. Never had a problem with my Toshiba Fire tv or my Vizio. Everything is up to date. Any suggestions appreciated.
