Compatible with screens that have VESA 50mm/75mm/100mm/200mm/200x100mm mounting hole patterns. Arm extends from wall up to 17.7" or folds flat to save space. The two arm assembly allows the full articulation of the monitor/keyboard, folds up to 3" from the wall and extends 17.7" to the center mounting of the monitor. This mount has two articulating joints which together provide 180 degrees of movement. Does this mount fits my LCD? If your LCD Monitor or TV has 4 or 6 holes on the back of the screen that are either 50mm,75mm ,100mm (4 inch) or 200 mm(8inch) apart from each other vertically and horizontally this bracket will fit. If there is a stand attached to your LCD TV this is usually removed prior to fitting the wall mount and the holes should be revealed.
