I sent all the new information to Samsung this morning. I had a reply from my previous message telling me they are investigating the issue.
I tested the three video clips that
@Dio sent me on a Q60T, TU7100 and RU7300 and the judder wasn't there. All sets had settings close to the same with all picture clarity off. I then tested on a Q95T that we had in the workshop and the judder was there.
I think this issue is only affecting the Q80T/Q85T, Q90/95T. Has anyone seen this issue on the Q70T?
Anyway, my contact at Samsung now has these video files to test himself and see it for himself.
Oh, and I couldn't see new software on the technical site for this issue depsite what
@Rudzki said.
As always, when I hear something, I'll keep you all updated.
