They don’t. My Hisense doesn’t nag me at all. I just use my Apple TV and 4k player and PS5 without issue. It’s not nearly as hard as all the comments here have made it out to be.
Maybe it’s more of a factor for people who watch over the air broadcasts or use cable TV. I haven’t used either in years.
Similarly, my Hisense TV never gets a chance to show the VIDAA interface. It just displays the HDMI input and I switch that between Kodi running on a Raspberry Pi and a VirginMedia TV box.
