TV surge protection helps limit damaging voltage spikes entering through the power connection, while filtering electrical noise that can affect connected AV equipment. Models with coaxial or Ethernet protection also help address surges traveling through those signal cables, adding another layer of protection for televisions, networked devices, and other connected equipment.

A wall-mounted TV surge protector uses a compact, low-profile design that plugs into or mounts near an existing outlet, with features such as rotating outlets and coax protection for tight spaces behind a display. A rack-mounted power conditioner provides multiple AC receptacles, power filtering, and installation in an equipment rack, with some models offering switched outlets, remote control, and higher load capacity for larger AV systems.

Count the power plugs for the TV, streaming devices, audio equipment, and other connected components, then add a few spare outlets for future additions or larger power adapters. TV surge protection options range from two-outlet wall plates and three- or six-outlet wall taps to eight- and ten-outlet power conditioners, so choose an outlet count that fits the installation without relying on outlet splitters.

Review the TV system’s available grounded outlet, voltage, load requirements, cord length, and space behind the display, then choose a wall tap, low-profile unit, or mountable conditioner that fits the installation. If signals use coaxial or Ethernet cables, consider surge protection for those paths as well, and check whether the device supports the required connections, mounting method, and outlet capacity.
