Yuri75 ,
Good afternoon, Yuri!
I didn’t dare, but I began to notice that this is not on all films / cartoons, on some everything is fine.
Someone from the forum once said that it depends on the compression of the movie format, maybe the way it is.
In general, I scored on this matter and enjoy the picture.
I also noticed that if you sit closer to the screen than its width, then the dots and blur will be much more pronounced, sit down a bit further and the picture will change dramatically for the better.
Maybe you too sit too close to the screen, do an experiment
