Question: what is the difference between q7 and q9 samsung tv?
Answer: 1-1 of 1 Answer Q6 is only model around 1000 nits of brightness whereas Q7-Q9 have 1500-2000 nits of brightness (extremely bright). Lastly, the local dimming areas grow in number from Q6 to Q9... since Q9 has hundreds of dimming areas enhancing blacks, bright objects don't have a halo effect across dark landscapes.
