Versatile 2-way HDMI 2.1 switching

This bidirectional switch handles 48Gbps bandwidth for 8K at 60Hz and 4K at 120Hz. It operates as a 2-in-1-out selector or a 1-in-2-out splitter. Console owners and home-theatre builders can route multiple sources to one screen or duplicate a single source across two displays without swapping cables.

Fits between sources and displays

Connect two devices such as a PS5 and Xbox Series X to one 8K TV or monitor, or send one Blu-ray player signal to a TV and a projector simultaneously. The unit manages HDCP 2.3 handshake and passes ARC audio back to a receiver. No external power supply is mentioned, so it draws what it needs from the HDMI links.

Signal integrity over long runs

Internal amplification and anti-interference circuitry preserve lossless video during extended sessions. The design prevents frame drops, black screens and colour distortion even with longer cables. VRR support keeps variable-refresh gaming smooth without added latency or visual artefacts.

Questions about this item

Will the 48Gbps bandwidth hold up without dropouts during long gaming sessions?

The switch uses internal signal amplification and anti-interference circuitry to maintain lossless transmission even with long cables during continuous use.

Does the unit stay cool and quiet when running 8K@60Hz or 4K@120Hz all day?

Passive operation with no fan means silent performance, while the amplified circuit design prevents heat build-up during sustained high-bandwidth loads.

Which HDMI cables and source devices are required to get 8K@60Hz or 4K@120Hz through this switch?

Certified Ultra High Speed HDMI cables plus an HDMI 2.1 source such as a PS5, Xbox Series X or 8K Blu-ray player and an 8K-capable display.
