Three-input HDMI 2.1 switch for multi-device setups

This SMUGDESK directional switch routes three HDMI 2.1 sources into a single display port, preserving full 48Gbps bandwidth for 8K at 60Hz and 4K at 120Hz. It suits living-room gaming rigs and home-theatre systems where the TV or projector has only one HDMI 2.1 input. Aluminium housing and gold-plated connectors maintain signal integrity without an external power supply.

Replaces manual cable swapping

The switch eliminates the need to unplug consoles, media players or PCs when a display offers just one HDMI 2.1 port. Upgrading makes sense when you run multiple 4K 120Hz or 8K 60Hz sources and want instant, lossless switching with HDCP 2.3, Dolby Vision, HDR10, HLG and Dolby Atmos pass-through intact. IR remote and front-button control give instant selection from the sofa or desk.

Verify source devices

Confirm each connected device outputs HDMI 2.1 signals and that the target display accepts 48Gbps bandwidth for the resolutions you need. Ensure cables are certified for 48Gbps to avoid link errors. The unit draws power from the HDMI bus, so no separate adapter is required, but very long cable runs may need active cables not covered by this switch.

Questions about this item

How many HDMI 2.1 sources can connect to the three-input selector?

The switch accepts three HDMI 2.1 source devices and routes the chosen signal to a single display port.

Does the IR remote require line of sight, and which button changes the active input?

The infrared remote works at distance and uses its input-select button; a front-panel button also cycles channels and the LED shows the active one.

Will the gold-plated ports need cleaning or the aluminum case require thermal paste over time?

No maintenance is needed; the gold-plated connectors resist corrosion and the solid aluminum housing passively dissipates heat without user intervention.
