Three-input HDMI switch for display expansion

This 3x1 HDMI switch adds three input ports to a single display output on an HDTV, monitor or projector. It is intended for users who need to connect multiple source devices such as games consoles, media players or set-top boxes without swapping cables. The unit includes an infrared remote and a front-panel button for source selection.

Passive operation with optional 5 V USB power

The switch draws minimal power from the HDMI lines and ships with a USB power cable for the 5 V port when sources cannot supply enough current. No fan or active cooling is present, so operation is silent. Power consumption in normal use remains low and is satisfied by the included USB cable from any standard USB port.

Gold-plated ports and compact 5-inch cable

All HDMI connectors are plated with 24K gold to resist corrosion and reduce tarnish over repeated insertions. A short 5-inch pigtail cable connects the switch to the display, keeping the unit close to the screen. The small form factor suits desktop or living-room placement where space behind the display is limited.

Questions about this item

How do I install the 3-port 4K 30Hz HDMI switch and which step is often missed?

Connect up to three source devices to the HDMI inputs, link the output to your display, plug the supplied USB power cable into the 5 V port, then press the button or use the IR remote to select the active input; the step users skip is powering the switch before expecting a signal.

What maintenance or replacement will the 3-port 4K 30Hz HDMI switch need later?

The 24 K gold-plated connectors resist corrosion, so no routine cleaning is required; only the IR remote’s battery will need occasional replacement.

What limit appears first during sustained use of the 3-port 4K 30Hz HDMI switch?

The 250 MHz bandwidth caps the signal at 4K 30 Hz with 12-bit deep colour per channel and 36-bit total, so extended sessions cannot exceed that throughput.
