To mount a TV on a wall, choose a location that won't cause glare, buy a bracket that fits the TV, and mount the unit so the middle of the screen is at eye level when you are seated. Also, make a plan for hiding the wires.
The ideal location for a mounted TV is on a large wall away from the glare from windows. Mounting the TV above a fireplace is common, but it causes viewers to strain as they look up to see the TV. Brackets come in fixed or adjustable styles. Fixed brackets hold the TV close to the wall but allow no movement. Adjustable brackets stick out but allow the user to swivel the set.
Installing an electrical outlet directly behind the TV is one solution for hiding the wires. Another option is to use a special cable raceway painted the same color as the wall.
