Not sure you have seen this issue it’s not just a very small bit of judder but looks the frame rate has halved. Also I have a Q60r in the bedroom which is fine but this issue on the Q90t downstairs so definitely a new issue on the 2020 T models!!!Don’t want to piss on everyone’s chips but Samsung have had this same issue for years & it’s not been fixed. Reckon a refund is on the cards. Does anyone know a modern TV that actually works straight out of the box?
