I purchased the Insignia™ - Fixed TV Wall Mount For Most 40"-70" TVs - Black
Model:NS-HTVMF0C. I reaseached this mount to be sure that it would work with my Samsung Model:UN65TU8000FXZA and determined both items were VESA compatible. The mount came with several screws but none of them were long enough for the back of the TV. I called Samsung and they told me that the vesa screw for Samsung Model:UN65TU8000FXZA was M8 22mm. In fact that screw did not fit. I determine the proper screw for this TV is the M8 43 MM 1.25. I thought I woould share so that no one else had to receive misinformation from Samsung about thier products.
