A:AnswerThe manual says to use M8 1.25 x 20mm, but I tried these and they were not long enough. With the mount and a washer the screw wasn't even catching the thread in the tv. The wall mount came with a bunch of screws including M8 1.25 30mm but these were too long. So I went out and bought them in a 25mm length and they worked.

A:AnswerThe model UN40N5200AFXZA does not have bluetooth so you won't be able to connect bluetooth speakers or headphones. I was surprised it did not have bluetooth because my 4-year old Samsung TV had this feature.
