3-Port HDMI 2.1 Switch for 8K Displays

This HDMI 2.1 switch connects three source devices to a single display. It supports 8K at 60 Hz and 4K at 120 Hz using the full 48 Gbps bandwidth. The aluminium housing dissipates heat during continuous use. It is built for gamers and home-theatre users who need to switch between consoles, streaming boxes or a laptop without swapping cables.

Driver-Free Installation With Push-Button Switching

The unit works immediately after connecting power and HDMI cables; no software or drivers are required. A physical button on the chassis selects the active input with a single press. The solid aluminium case prevents overheating that can cause signal drop-outs or device crashes during long sessions. Ensure all cables meet the 48 Gbps specification to avoid handshake issues.

Ideal for Multi-Console Setups Not for More Than

This switch suits owners of a PS5, Xbox and streaming device sharing one 8K or high-refresh 4K screen. It also fits a laptop dock that must drive a monitor alongside consoles. Buyers who need four or more simultaneous inputs should look at a larger matrix switch. Users with only legacy 1080p equipment will not benefit from the 2.1 bandwidth.

Questions about this item

How can I confirm the switch is passing 48 Gbps bandwidth and 4K 120 Hz after setup?

What cables and power supply are included, and what must I provide?

The unit itself is supplied; three HDMI 2.1 cables for the inputs and one for the output must be purchased separately, and no external power adapter is required.

Which version should I choose for a PS5 or Xbox running 4K 120 Hz with VRR?

This single 3-input 1-output model supports 48 Gbps, 4K 120 Hz, VRR, ALLM and HDCP 2.3, matching the console requirements.
