A:Answer Hi Rosie, the 55" AU8000 features a VESA mounting pattern of 200 x 200. You will need 4 M8 screws, 11-13mm in length, 1.25mm pitch. You can download the AU8000 TV's User Manual, e-Manual, Remote Control Leaflet, and Quick Setup Guide on Samsung's website by clicking "Support" > "Manuals & Software" > "TVs & Home Theater" > "TVs". From there, you can select the AU8000 TV under "Crystal UHD TVs” > “A Model Lineup" and download the guides you would like. ^Tim
