With fully automated movement, the VLMF109 can extend up to 9 inches from the wall and swivel up to 60-degrees. Thanks to the mount’s 1.99-inch thick motor, when retracted, the TV sits only 2 inches from the wall for a low-profile appearance. It also includes two presets (macros) for pre-selected TV viewing positions and placement. When turned off, the mount automatically returns to the home position, which is also programmable.
The VisionMount VLMF109 Motorized Full-Motion Mount accommodates flat panel TVs from 37 to 56 inches and up to 110 lbs. It is available for a list price of $429.99.
