best hdmi switch for tv

The selection includes HDMI 2.1 devices with full 48 Gbps bandwidth and HDMI 2.0 devices around 18 Gbps. Some splitters also report per-channel amplifier bandwidth (for example, 12 Gbps per channel within a 48 Gbps total).

Listings warn that for optimal 8K performance you should keep HDMI cable runs very short—about 2 meters (~6.5 ft) or less on several models. For 4K, longer runs are tolerable; guidance ranges up to about 4–5 meters (~13–16 ft) depending on the model.

These devices are described as compatible with common HDMI-equipped gear: computers, game consoles, streaming media players, Blu-ray/DVD players, cable/satellite boxes, and standard TVs, monitors, or projectors.

Many units offer one-button switching plus indicator lights; several also include an IR or wireless remote for changing inputs from across the room.

Audio support ranges from uncompressed LPCM and common compressed formats (DTS, Dolby Digital) to advanced codecs on some listings: DTS‑HD and Dolby TrueHD are named, and one extender listing also mentions Dolby‑AC3, DSD and multichannel audio up to 7.1.

Power options vary: many switches use USB‑C/USB Type‑C power or include a USB power cable (some recommend a 5V adapter); some compact bidirectional switches require no external power; other units include an AC adapter, and a few 4K models reference a micro‑USB power cable.
