I started a thread related to this a few months ago. Often, when I go to Netflix, I will get the big Logo on the screen for several seconds, then my TV tells me the HDMI signal has been lost. Remembering what Bobby told me then, I disconnected then reconnected the Hopper HDMI cable and everything goes back to normal. A bit ago, following that, I selected a movie and watched the percentage circle increase, get to 99%, then start back to 0. After a few rounds of that, the No HDMI signal came back on, requiring playing with the cable again. It's a fairly new cable, so I doubt it's the problem. So far, my history with H3 Netflix has been frustrating. I just go back to my Roku. Any ideas? Also, does the H3 Netflix interface show groups of 4K shows on the main menu like on Roku?. I could not find anything.
