Bi-Directional HDMI 2.1 Switch

This manual switch connects two HDMI sources to one display or one source to two displays, toggling between them with a button press. Only one display is active at a time in splitter mode. It requires no external power and helps prevent port wear from repeated plugging and unplugging.

Ports and cable compatibility

The unit provides two HDMI 2.1 ports supporting up to 48Gbps bandwidth. Verify that your source devices and cables are rated for the resolution and refresh rate you intend to use, such as 4K at 144Hz or 8K at 60Hz. Both connected displays must share a compatible EDID for the signal to pass correctly.

Sustained high-bandwidth operation

Under continuous 8K@60Hz or 4K@120Hz loads the passive design relies on cable quality and source signal strength to maintain link integrity. VRR and Dynamic HDR metadata pass through without active re-clocking. Long cable runs at the highest data rates may introduce instability that a powered repeater would otherwise mitigate.

Questions about this item

What cables come in the box and do I need to buy HDMI cables separately?

The box contains only the switch unit; you must supply three HDMI 2.1 cables yourself — two for sources and one for the display.

Should I use this as a 2×1 switch or a 1×2 splitter for my 4K 120 Hz console?

Use it as a 2×1 switch to connect two consoles to one 4K 120 Hz screen; the 1×2 mode toggles between two displays but never shows both at once.

Will the 48 Gbps bandwidth actually deliver 4K 120 Hz with VRR and HDR on my PS5?

Yes, the 48 Gbps link supports 4K at 120 Hz with VRR, Dynamic HDR and HDCP 2.3, matching the PS5 output spec.
