Bi-Directional HDMI 2.1 Switch

This HDMI 2.1 switch connects two sources to one display or one source to two displays. It supports 8K at 60 Hz, 4K at 120 Hz, 1440p at 165 Hz and 1080p at 240 Hz. Gamers using a PS5 or Xbox Series X can reach 4K 120 Hz on a compatible TV. The unit includes an HDMI 8K cable and a USB power cable for unstable power situations.

Manual Switching With Cable Length Limit

Pressing the select button toggles between the two connected displays; both screens cannot show content at the same time. Each HDMI cable run must stay within 3 metres to maintain signal integrity. The compact design weighs 0.068 kg and carries an 18-month warranty with 24-hour email support.

Upgrade For Single-Port Displays

This switch replaces the need to repeatedly swap cables when a display has only one HDMI 2.1 input. It also solves the problem of routing one high-bandwidth source to two different screens. Buyers who need simultaneous output on both displays should look elsewhere, as this device only switches.

Questions about this item

What does the HDMI 2.1 interface support on this switch?

It handles 8K at 60 Hz, 4K at 120 Hz, 1440p at 165 Hz and 1080p at 240 Hz with a 48 Gbps bandwidth ceiling.

What cable length and power does the unit require to fit?

Each connected HDMI cable must stay within 3 metres, and a USB power cable is included for cases where the source cannot supply enough current.

How do I set it up and what is the common mistake?

Connect the sources and displays, add USB power if needed, then press the select button to toggle — the mistake is expecting both screens to show content at the same time.
