Upgraded from 4th gen but finding the video jerky (juddery) reading various things not sure what my hdmi is but isn’t hi speed or anything I doubt.

If I get new hdmi will this sort the issue?
 
What content is it being jerky on? Typically a recommended HDMI cable does sort a lot of problems out for sure. The Belkinones in the Apple Store are cheap enough and correct most people's problems, especially with the sticky menus for one.
 
iTunes 4k films mainly but also prime video etc.

I’ll try the Belkin HDMI have read good things, also should I have it 60hz hdr or something else?

Yeah 100% change the cable. As the others have said match content/frame rate etc. Little tip though, especially if you are using the aerial screen savers and your TV does Dolby Vision. Set the default to DD 60hz as it doesn't seem to do match content when playing the screen savers so if you have it set to anything other than 4K DD/60Hz they are either in SD definition or in the wrong frame rate at 50hz. If the TV doesn't do DD then set the standard to 4K SD/60hz :D

Samsung, they don't 'do' Dolby Vision due to licensing and Samsung being behind HDR10 as a format. Think VHS and Betamax :D So set the ATV to 4K SD/60hz :D

You definitely need a new HDMI cable. The marketing gimmicks for them is abhorrent, and really unclear to the consumer. I went through 4 before I realized why I was bing dupped! Ended up ordering the Belkin from Apple and problems solved! I have a Sony so can't comment on the Dolby and Samsung thing.

What's wrong with your TV? No idea I never said there was anything wrong with it, just saying it dines't display Dolby Digital because Samsung don't license DD for their TV's

No i meant why cant i use HDR setting there's nothing wrong with the tv and the picture is amazing through the atv4k best ive seen it do (apart from the judder)
 
Oh sorry, yeah I mean for the aerial screen savers. They are only in either SD or DD and with matched content not working when using the aerial screen savers is make them look all very weird.

Yes almost identical. Decided it was the TV that was screwing me, or the cable. After endless searching I started looking very closely at the cable bandwidth and found the the Belkin had bandwidth at up to 48Gbs. That was double what I was finding on amazon and at walmart claiming high speed. So YMMV but I haven't had an issue since.
 
Gonna get the cable

Change the settings as above, and see

Hope it sorts it all out

Funnily enough think the aerial screen savers are wicked and no judder lol
