Avoid mounting a TV above a tall fireplace mantel because it often results in uncomfortable viewing angles and potential heat damage. The high position causes neck strain during viewing since the TV sits well above eye level. Additionally, heat rising from the fireplace risks damaging the TV's components over time. A tall mantel also disrupts the room’s visual balance and layout. For better comfort and safety, place the TV in a nook or at eye level within a dedicated media wall instead.
