I setup my q90t yesterday and have everything running in intelligent mode for the meantime. I couldn't handle how fast motion video on cable TV looks, so I disabled Picture Clarity aka Motion Blur Settings. My panel isn't the greatest, shows some DSE more noticeable on gray and whites, but also sorta on solid colors. Also have a bad shadowing in Netflix top left when showing white banner with caption options is displayed.
Looking around, no one seems to have a perfect panel, when would it be a good idea for a replacement? I have extended holiday return til Jam 2021. I just hope I don't regret keeping this TV when I get the Xbox Series X in November.
