I have always had the "Auto-adjust display refresh rate" turned off on my 2nd gen Ultra (4660x). I have never noticed any stuttering on content filmed at 24fps or any other frame rate. Am I one of the lucky ones who's not sensitive to this mismatch? Or am I just not paying attention? I watch a lot of English and European shows on the PBS app, Korean shows on Netflix, as well as movies and TV on Apple, Amazon, Max, Hulu and Peacock. I think I have noticed it on Thursday night football on Amazon but I didn't know what the cause was.
FWIW, the Roku feeds a Denon AVR which goes to a 2017 Samsung KS8000.
