I'm starting a new post to see if this goes further.
The local dimming on the q9fn still isn't resolved,
I started a petition to see if samsung at least acknowledge the problem, I cannot post the petition here because the forum doesn't allow me. But if you go to change.org look for local dimming and click there, please spread this.
I bought and LGc8 because my child broke my q9fn, but still I want this to be solved.
