Three-Source HDMI 2.1 Switch

This 3×1 HDMI 2.1 switch connects up to three source devices to a single display, handling 48Gbps bandwidth for 8K@60Hz and 4K@120Hz signals. It supports HDR10+, Dolby Vision, VRR and ALLM for gaming, plus lossless Dolby Atmos and DTS-HD audio pass-through. HDCP2.3 and HDCP2.2 compliance ensures protected content plays correctly across consoles, PCs and media players.

Driver-Free Integration

The unit operates without external power or driver installation, drawing what it needs from the connected HDMI cables. An IR remote and a front-panel button let you change inputs from the sofa or at the device. Backward compatibility with HDMI2.0 and 1.4 means legacy 1080p and 4K60 sources work alongside newer 8K gear, simplifying a mixed-generation setup.

Home Cinema and Gaming Hub

Ideal for owners of a PS5, Xbox Series X, laptop and Blu-ray player who share one TV or projector and want zero-latency switching. Buyers needing more than three inputs, bidirectional matrix routing, or CEC-based automatic switching should consider other solutions, as this model is a fixed 3-in-1-out selector.

Questions about this item

What is the maximum bandwidth the switch can sustain during long sessions?

The switch uses a 48 Gbps HDMI 2.1 chip that maintains full bandwidth for 8K at 60 Hz and 4K at 120 Hz without throttling.

Does the unit generate noticeable heat or fan noise when left on all day?

It has no fan and draws power from the HDMI sources, so it runs silently and stays cool during continuous use.

Which cables and source devices must I already have to use this switch?

You need three HDMI 2.1 cables and up to three sources such as a PS5, Xbox Series X, laptop or Blu-ray player plus one display.
