I’ve been plagued with motion Judder and blurring with my 2021 QE55QN94A TV which makes football and F1 very difficult to watch. I initially thought it was my Sky Dish so bought a new one and had it repositioned. It now gives 100% Signal Strength and Quality. I then replaced my Sky+HD box but non of these have improved the situation. I also get the problem on Terrestrial channels and not just football. I have tried all the settings and adjustments and lots of other recommended ‘potential’ solutions but to no avail. I decided to join the Samsung community to seek advice but I can see that many of Samsung’s customers are also suffering the same issue on this flagship TV with no solutions being offered. I guess Samsung TV’s are no longer a quality product so returning it is the only option.
Unfortunately no effect whatsoever ever - I had already tried this several times along with Picture and TV resets, changing the HDMI lead and moving the router to another location as requested by Samsung technical help. The other aspect I noticed is it gets worse the longer the program goes on.
