Three-port HDMI 2.1 switch for multi-source setups

This BUCIER switch routes three HDMI 2.1 source devices to a single display. It suits gamers and home-theatre users who own a PS5, Xbox Series X and a PC but have only one HDMI 2.1 input on their TV or monitor. The unit is powered by USB and includes an IR remote plus a front-panel button for manual switching.

48 Gbps bandwidth handles 8K at 60 Hz

The 48 Gbps link supports 8K@60 Hz, 4K@120 Hz and 1080p@240 Hz with HDR and eARC passthrough. All three sources and the display must use HDMI 2.1 cables rated for 48 Gbps to reach these modes. If any cable or device falls back to HDMI 2.0, the switch will negotiate the lower common rate and 4K@120 Hz will not be available.

Replaces manual cable swapping or basic 2.0 switches

This unit upgrades from repeatedly unplugging cables or using an older 18 Gbps switch that caps at 4K@60 Hz. The jump is worthwhile when you have three 8K- or high-refresh 4K-capable sources and need reliable auto-switching with remote control. It does not split one source to multiple displays and cannot add HDMI 2.1 ports to a display that lacks them.

Questions about this item

Will the 3-input HDMI 2.1 switch pass 4K at 120 Hz from my PS5 to an older 4K 60 Hz monitor?

The switch supports 4K@120Hz pass-through, but the connected monitor must also support 4K@120Hz to display that rate; an older 4K 60 Hz panel will only show 60 Hz.

How can I confirm the switch is delivering 8K at 60 Hz or 4K at 120 Hz after I connect everything?

Use the TV or monitor’s on-screen information menu to verify the active resolution and refresh rate; the switch forwards whatever the source and display negotiate.

What comes in the box and do I need to buy any cables or a power adapter separately?

The package includes the 3×1 HDMI 2.1 switch, a USB power cable and a user manual; three HDMI 2.1 cables for the sources and one for the display are not included.
