Warm Reminder: Please check if your monitor has 75 x 75 mm or 100 x 100 mm VESA holes at back of monitor before purchasing; For some big size such as 49 inch Samsung monitors, they need to install a steel part (it always comes with your monitor; It doesn't come with monitor arm package) to get 75x75 mm or 100x100 mm VESA holes; Then you can install monitor arm successfully
