I noticed after the most recent TVOS update (11.2, I believe, which allows the automatic video switching), my TV screen goes black for 2-3 seconds when transitioning from an app back to the home screen and sometimes when going from video in an app back to that app's menu. I'm assuming that the resolution is changing or something. I'm using SDR, since my 4k TV is a couple of years old. Anyone else experiencing this?
