For a typical flat panel installation, with a tilting wall mount and equipment located directly below the TV, 8-foot cables will work nicely. Twelve-foot cables will allow you to make connections before the TV is on the wall, or pull out the equipment once it is hooked up. If you’re mounting a TV higher than normal (the bottom of the average TV is between 36 inches and 46 inches from the floor) or using a full-motion mount, you need 12-foot cabling. If that seems excessive, consider this: On a typical full-motion mount with a 20-inch arm, you will use 3 to 4 feet of cable before even reaching the wall; that is, if it’s properly routed to allow safe movement of the TV on the arm.
