+1 for Ghosting Issue
Wanted to share my experience with the 82" q6FN. I too have noticeable ghosting. I first saw it when scrolling through Samsung menus when first setting up the TV, figured it was just a weird glitch with the menus. But then last night I'm watching the old classic Charlie Brown's X-MAS, and it was horrible. Every movement of the characters had this god awful ghosting, so i started researching and came across this thread.
I have run the Motion Blur test on You Tube and the Earth 2 4K video previously posted, and sure enough... my ghosting is just as bad as what others are sharing. Ugh, now what to do??
This TV is a replacement of my MU8000 that I had screen clouding issues with. After several panel replacements, Samsung gave me a refund through Best Buy and so I decided to upgrade to this years Q6. I've had the set for about a week now and overall I was thrilled at how much better the PQ is on this set, but now this. I can say without question my older MU8000 did not have this motion blur/ghosting issue. Also as as a side note, the DSE is noticeable.. but having gone through multiple screens with my MU8000 replacements, you're always going to have some DSE on these sets.
Anyway back to this issue, what to do now? I wonder, is this correctable through a Firmware upgrade or is it a physical defect of the panel? Given that others are also experiencing this issue, I'm thinking an exchange probably isn't going to solve the problem, so the question is do I return and just be done with Samsung once and for all?
Maybe I should go with the Sony X900F? I do play alot of Xbox and the variable refresh rate is what drew me to this over the Sony, but this motion blur might be a deal killer now. UGH.. cmon Samsung, why do you do this!!??
