Hi columbus, this Samsung TV is VESA Compliant and works with any wall mount or stand that is also VESA Compliant and designed for the TV's size. For the 55" QN90A TV, you would need a VESA bolt pattern of 200 mm x 200 mm. Screws and adapters are not included with your TV. You will need 4 x M8 screws, 11 - 13 mm length, and 1.25mm pitch. ^Val
