for example, if I am watching something on ROKU chan and then go watch something on Prime app, and come back to watch the thing on ROKU chan, in is now jerky, unless I exit to roku settings display and change them again to 4k HDR 30fps.
I have seen a lot of posts on this but no solution unless drop roku and try something else (like was just using the built-in on my Vizio V-436-G1 - works but seems cumbersome. Or maybe I'm just not used to it.
Thanks! ROKU 4662X HDMI high end cables, etc etc etc 4K.
I actually had been bouncing between display=auto and manually defining it as 4k HDR 30, since it won't change anything if I use the same method and frame rate prob continues. So I bounce between the 2.
Problem occurs either way. auto picks 30 so I assume it is not 60 capable. When I tried to force 60 yesterday it gave me an X", so the ROKU thinks not .
Yes, It's bout 1-2 years old - beautiful display!!! Fabulous demo stuff off YouTube.
This is a firmware problem. Somehow I have to get their attention to fix it. it is on auto update and always connected to RJ45 so always on latest, though I check to be sure.
The 4630 did everything I needed. I bought the 4662 like a fool hoping it would fix the frame rate prob. it did not.
I did not know about that setting in Vizio. I found that it is available for the ROKU but not for my 4K Sammy BR Player(see below) . So I set it on for the Roku and went and set Display=auto (it chose 4K HDR 60) in ROKU and tested, and played Prime non HDR film, and tested, and played Prime HDR film, and tested, and NO FRAME SKIP/RATE ADJUST.

You're welcome - its a common HDMI signal setting for HDR TV's, and its almost always disabled/off by default (for compatibility reasons), requiring the user to go in and change it to "Deep Color" or "Full Color" "Enhanced Mode" etc.
If you have an HDR-capable AVR/soundbar that does HDMI passthrough, they also have such a setting.
Again, many thanks for the education!!! My soundbar is an LG LAS454B that is 2.1 (a few years old) and only has optical input (not HDMI) which I connect to my TV. It looks like the next step up to get HDMI soundbar would be about $280 for an LG SN6Y so that is "futures" for now. but thanks as I did not even know about it. Good stuff!!!
