Just wanted to bring this back up in case there’s a solution, thanks!I use an Apple TV 4K to watch ATV+, Netflix, Amazon Prime and Spectrum cable. The ATV is set to automatically detect video formats.
What I find annoying is that the TV blanks out when switching to HDR. The TV launches into Netflix and others fine, but then when I select to start the movie or show I get about a 2 second blank screen before the content starts. Is there a way to prevent this, or is it just the nature of the beast?
