You will also probably need to save more space in you living room and do not want to put the new expensive television on the regular TV stand.
The answer to this is the articulation dual extend TV wall mount and the reason for that is that the dual extend will provide the strong support than a single extend. These TV mounts because of the articulating functionality will be able to extend from the retractable position to about 15.4 inches. They can retract back to about 3.5 inches from the wall.
This is definitely worth the buy but before buying make sure that you have the right specifications. These specifications are usually listed at the back of the LCD TV. Also check that the TV mount manufacturer follows the VESA guidelines.
