4-input HDMI 2.1 switch for gaming consoles

This HDMI 2.1 switch connects four source devices to a single display, supporting 48 Gbps bandwidth for 8K at 60 Hz and 4K at 120 Hz. It is built for users running a PS5, Xbox Series or similar consoles alongside a PC or streaming box. The compact plug-and-play design fits cleanly into a home entertainment or gaming setup without external power requirements.

Sustained high-refresh signal stability

The switch maintains stable signal transmission during extended gaming sessions at high refresh rates, preserving HDR metadata and resolution without dropouts. Bandwidth headroom of 48 Gbps handles the continuous data flow required for 4K 120 Hz gameplay across long periods. Active switching keeps the link trained so the display does not renegotiate when changing sources.

Replaces manual cable swapping

This unit replaces the need to physically swap HDMI cables when moving between multiple consoles or a PC. It upgrades from switches limited to 4K 60 Hz, enabling full 4K 120 Hz and 8K 60 Hz capability for current-generation hardware. The jump is worthwhile when your display and sources support HDMI 2.1 fixed-rate link features.

Questions about this item

Does the 48 Gbps HDMI 2.1 switch generate noticeable heat or fan noise when running all day?

The compact plug-and-play design has no fan and runs passively, so it stays silent and only produces minimal warmth during continuous use.

What cables or power supply must I already own to connect four sources to one display with this switch?

You need four HDMI cables for the inputs and one HDMI cable for the output; the unit draws power from the source devices so no separate adapter is required.

Will the 8K 60 Hz and 4K 120 Hz capabilities work properly with my older PS4 or 1080p projector?

Yes, the switch is backward compatible and will pass whatever resolution and refresh rate the connected source and display support, including 1080p signals.
