A:AnswerYou can lock your TV to the arm assembly with the locking screw.
The TV can swivel, this feature doesn't have a lock.
Maybe try a fixed wall mount so the TV won't move.
A:AnswerA 23-inch articulating arm moves the television away from the wall, and a 50-degree swivel mechanism offers multiple positioning options. Make sure you leave enough room for the TV to swivel.
