One or two things I did note, was some dse on mordernwize dse YouTube vid.. but nothing I can see while watching normal content and not as bad as my js9000 which I’ve never noticed dse on before the stress test.. I’m going to update the tv later this evening and see what that brings as I did notice a few flickers on certain scenes from YouTube 4K hdr. (The only way I can describe them is like when you saw a pinstripe suit in full 1080p when hd was new) I have seen on other sites that firmware has fixed some of these issues so I’ll see. To be honest though these things I’ve noted are very mild and I’m super picky over TVs (sent back my last 4 sets of different types) and this one for me is a keeper!! Best tv I’ve ever set eyes on!
