A:AnswerThe mount is not adjustable - it is made specifically to allow the TV to rest flat against the wall. If you need downward tilt you must use a mount that has that capability - all of those that I know of space the TV at least 3" off the wall when vertical but will allow the bottom of the TV to rouch or nearly touch the wall when tilted.
A:AnswerPretty sure it will, be use the mount is for Samsung 75” tv. Recommend that you buy a different bracket from BestBuy so you have room to install your light strip purchased from BestBuy. The mount did the set flush without a gap, mine is tilting down.
A:AnswerThe Q8FN does not have a One Connect box therefore all the cables are connected to the back of the tv making it not as flush as the Q7 n Q9 models which have the One Connect box
