Our Verdict
Samsung Q8FN/Q8/Q8F QLED 2018
Samsung Q9FN/Q9/Q9F QLED 2018
The Samsung Q9FN is slightly better than the Samsung Q8FN. The Q9FN has better dark room performance thanks to the better local dimming feature and better black uniformity. Overall performance is very similar between the two. The Samsung Q8FN doesn't use the One Connect box and all connections run to the back of the TV towards the side.
