4×1 HDMI 2.1 Switch 48Gbps

This 4×1 HDMI 2.1 switch connects four source devices to a single display, solving the problem of limited HDMI ports on a TV or monitor. It handles 48Gbps bandwidth with full HDMI 2.1 compliance, enabling native 8K@60Hz and 4K@120Hz output. The unit supports HDCP 2.3, HDR10+, Dolby Vision, VRR and ALLM for protected UHD content and smooth gaming. Switching is handled by an included IR remote or a front-panel button with LED channel indicators.

Best for multi-source home cinema and gaming setups

The switch suits owners of multiple consoles, a media player and a laptop who want one-cable connection to a high-refresh display. It works with PS5, Xbox and Blu-ray players without drivers or software. Buyers who need to send one source to multiple screens should look at a splitter instead. Anyone requiring more than four inputs will need a larger matrix solution.

48Gbps HDMI 2.1 bandwidth decides compatibility

Full 48Gbps throughput is the single spec that determines whether this switch passes 8K@60Hz, 4K@120Hz, VRR and ALLM without compression. Lower-bandwidth switches drop dynamic HDR or high refresh rates. Verify that both your sources and display support HDMI 2.1 to use the 48Gbps path. The switch draws power from the HDMI bus or an optional USB connection for marginal signal conditions.

Questions about this item

What HDMI cables and sources do I need to use the 4×1 switch at 48Gbps 8K@60Hz?

You need four HDMI 2.1-certified cables and source devices that output HDMI 2.1 signals such as a PS5, Xbox Series X, recent GPU or 8K media player; the switch itself provides the single 48Gbps output to the display.

Will my older 4K@60Hz HDMI 2.0 console or laptop work through this HDMI 2.1 switch without downgrading the other ports?

Yes, the switch is backward-compatible so an HDMI 2.0 device runs at its native 4K@60Hz while the remaining ports still pass full 48Gbps 8K@60Hz or 4K@120Hz signals to the same display.

How do I confirm the switch is passing 48Gbps HDR10+ or Dolby Vision correctly after I connect everything?

Check the front-panel LED to see the active input, then verify on the TV or monitor that the info bar shows 8K@60Hz or 4K@120Hz with HDR10+ or Dolby Vision active and that VRR or ALLM indicators appear during gaming.
