The best angle for a wall-mounted TV is typically eye level when seated. This ensures comfortable viewing without straining your neck. It is important to consider the height of the furniture the TV is mounted above and adjust accordingly. Additionally, tilting the TV downwards slightly can help improve the viewing experience, especially if the TV is mounted higher than eye level. It is recommended to follow the manufacturer's instructions for the specific wall mount being used to achieve the desired tilt angle. Make sure to secure the TV properly to the wall mount to avoid accidents. Remember, the best angle may vary depending on the size of the TV and the room's layout.
