We just installed this articulating dual arm wall mount in a San Antonio, TX living room.  The room had a massive fireplace that forced us to place the TV off to one side.  We utilized the articulating mount to angled the HDTV into the room for better viewing.  The dual arm wall mount also allows for the HDTV to pushed back and sit flush against the wall when not in use.  This is by far our most popular and versatile wall mount.
