What this HDMI 2.1 switch does

The BUCIER unit is a bi-directional HDMI 2.1 switch with three ports. It lets you connect two sources to one display or one source to two displays, switching between them with a button press or the included remote. It supports 8K@60Hz, 4K@144Hz, 4K@120Hz and 1080P@240Hz. It is aimed at gamers and home-cinema users who need to share a single screen between a console, PC or streaming stick.

Installation and common issues

The device is plug-and-play with no drivers or apps required. A USB-C power cable is included; connect it only if your HDMI port cannot supply enough power for stable operation. HDMI cables are not included, so you must provide three cables of suitable length. The aluminium housing aids heat dissipation during extended use. Switching is instant once all cables are seated firmly.

Check your setup before ordering

Verify that your sources and display support HDMI 2.1 to use the full 48Gbps bandwidth and high refresh rates. Confirm you have three HDMI cables rated for the resolution and refresh rate you need. Ensure a spare USB port or charger is available nearby in case external power is required. The switch handles one active output at a time in splitter mode.

Questions about this item

How do I confirm the switch is passing 48Gbps for 8K@60Hz after I connect everything?

The LED on the button lights to show the active port; a compatible display will report 8K@60Hz or 4K@144Hz in its on-screen information menu.

What cables and power items are included versus what I must provide?

The box contains the switch and a USB-C power cable; you must supply three HDMI cables because none are included.

Should I choose this model for a dual-monitor gaming setup or for switching two consoles to one TV?

This bi-directional unit handles both — two sources to one screen or one source toggling between two screens, one at a time.
