Three-input HDMI 2.1 switch for multi-console setups

This 3×1 HDMI 2.1 switch connects three source devices such as PS5, Xbox Series X/S, Nintendo Switch or a PC to a single display. It is designed for gamers and home-theatre users who need to swap between 8K@60Hz or 4K@120Hz sources without unplugging cables. The unit handles HDR10, Dolby Vision and lossless audio formats including Dolby Atmos and DTS:X. Plug-and-play operation requires no drivers.

Full 48Gbps bandwidth with HDCP 2.3 compliance

The switch delivers the complete HDMI 2.1 48Gbps specification, natively supporting 8K at 60 Hz and 4K at 120 Hz while remaining backward compatible with 1080P at 240 Hz. HDCP 2.3 decoding ensures stable playback of encrypted UHD streaming content. VRR and ALLM are supported for lag-free high-refresh gaming. CEC pass-through lets a TV remote control connected consoles.

Three switching modes with optional USB-C power

Intelligent auto-switching activates when a new device powers on, a front button provides local selection and an IR remote enables couch control. The unit is bus-powered over HDMI but includes a USB-C auxiliary power input for demanding configurations. It is not suited for buyers who need more than three inputs or who require HDMI 2.1 features beyond the 48Gbps baseline.
