I really need to know why Samsung electronics can't solve a fundamental feature such as motion handling. Is this so difficult to you? All D series have this issue which is briefly about random frame rate drops and slowdown of slow motion scenes it can't cope with the cadence of vedio fps. Shame on these tv sets. I have been waiting for a firmware fix this bug but with no vain. I literally regret buying this tv and will return it soon. Thanks Samsung
The motion processing issue you're experiencing, where there are random frame rate drops and slowdowns during certain scenes (especially slow-motion content), may be linked to the motion interpolation and frame rate conversion features that are part of the TV's settings. Samsung uses technologies like Auto Motion Plus and Motion Rate to process video for smoother motion, but sometimes these features can introduce artifacts or fail to properly handle certain frame rates, especially with slow-motion content.
I have the same issue , own a 75'' qn90d. the fps drop is due to Samsung trash motion processing , on my tv, if I enable game mode it fixes this issue, but going back to movie mode it still stutters even if you see picture clarity settings is off. So the culprit is that picture clarity wasn't turned off completely even though it shows off. Again trash samsung software bug.
Sometimes, I can reset movie mode picture settings then turn on picture clarity settings then turn it off. That will sometines reset the motion processing and turn it off for good.
There was a big thread about this exactly same issue for Samsung 2020 QLED TVs. They released a firmware update in 2022 to fix it. It is so ridiculous that Samsung still has the same issue in 2024 TV. Who knows if Samsung will fix it this time and when.
Right now temporary solution is to use game mode. Never buy Samsung again.
