I find that most of those reset to some nonsense occasionally or whenever the power goes out. I make sure they have no internet connectuon, but I usually have to dig up the remote to get back to hdmi1 so my device interface will come back up. I accept the annoyance because I accepted the discount that they give to have all of the spyware crap on there that I am blocking. I wish they could sell something cheaper that is just a display, buy product managers will be product managers.
