Three-input HDMI 2.1 switch

This HDMI 2.1 switch connects three source devices to a single display port. It solves the problem of limited HDMI inputs on TVs, monitors or projectors. The unit is designed for home-theatre and multi-console gaming setups that need uncompressed 8K or high-refresh 4K signals.

48Gbps bandwidth with HDCP 2.3 and HDR

Full 48Gbps bandwidth delivers native 8K at 60Hz and 4K at 120Hz without compression. HDCP 2.3 support keeps protected streaming and Blu-ray content playing correctly. Dolby Vision, HDR10 and HLG pass through unchanged, and Dolby Atmos audio is carried to the display or receiver.

Manual switching and bus power

A front-panel button selects the active input and an LED shows which port is live. The switch draws power from the connected sources so no external adapter is required. Gold-plated connectors reduce signal loss. Check that each source and the display support HDMI 2.1 and the desired resolution before ordering.

Questions about this item

Will the gold-plated HDMI 2.1 ports need replacement over time?

The gold-plated ports resist oxidation and signal loss, so they do not require scheduled replacement under normal use.

What bandwidth ceiling limits 8K@60Hz or 4K@120Hz throughput?

The 48 Gbps HDMI 2.1 bandwidth is the hard ceiling; signals above that rate cannot pass.

Does the bus-powered switch get hot or draw extra power during all-day use?

It draws power from the connected sources and stays cool because no active cooling or external adapter is involved.
