Bi-Directional 2x1 HDMI Switch

The WRIARICH HDMI Bi-Directional 2x1 Switch Splitter handles two roles in a compact black unit. Connect two HDMI sources to one display and switch between them with a button press, or send one source to either of two displays. Only one display operates at a time in the splitter mode, so simultaneous output is not supported.

Gamers and multi-console owners

This switch suits setups that alternate between a PS5, Xbox Series X or high-refresh gaming PC and a single monitor or TV. It also fits users who move a single source between a living-room TV and a desktop display. Buyers who need both screens active at once, or who require automatic switching without pressing a button, should look at a different solution.

48 Gbps HDMI 2.1 bandwidth

The single specification that decides compatibility is the 48 Gbps HDMI 2.1 link with HDCP 2.3. It carries 8K at 60 Hz, 4K at 120 Hz, 2K at 144 Hz and 1080p up to 240 Hz alongside Dynamic HDR, Dolby Vision and Dolby Atmos. Cable runs must stay within 1.5 metres for 8K or 3 metres for 4K at 60 Hz to maintain signal integrity.

Questions about this item

Does the switch generate heat or noise when left running all day?

The unit is a passive HDMI 2.1 bi-directional switch with no fan or active electronics, so it produces no audible noise and negligible heat during continuous use.

Which cables and source devices must I already own to reach 8K60 or 4K120?

You need HDMI 2.1-certified cables — 1.5 m maximum for 8K60, 3 m maximum for 4K60 — plus a source and display that both support 48 Gbps, HDCP 2.3, Dynamic HDR, Dolby Vision and Dolby Atmos.

Will my older 1080p 60 Hz monitor work alongside a new 4K 120 Hz display on the same switch?

Yes. The switch passes 1080p at 24, 50, 60 and 240 Hz as well as 4K at 60 and 120 Hz, so a legacy 1080p60 screen and a modern 4K120 screen can share the device — only one display is active at a time.
