Three-Source HDMI 2.1 Switch

This SMUGDESK switch connects three HDMI sources to a single display using HDMI 2.1 at 48Gbps bandwidth. It supports 8K resolution at 60Hz and 4K at 120Hz for gaming consoles, streaming devices and PCs. The unit simplifies cable management by eliminating the need to swap leads manually.

Passive Operation With Remote Control

The switch draws power from the connected HDMI sources so no external adapter is required. It operates silently with no fan or moving parts and adds negligible power draw to the chain. Source selection is handled by an included IR remote or a front-panel button for convenient switching.

48Gbps Bandwidth For 8K60 And 4K120

The 48Gbps throughput determines whether the switch can carry uncompressed 8K at 60Hz or high-refresh 4K at 120Hz with HDR, VRR and ALLM. Buyers needing more than three inputs or requiring HDMI 2.0 legacy fallback should verify compatibility before purchase.

Questions about this item

How do I connect the three HDMI sources and the display to the 3-in-1 switch?

Connect each source to one of the three HDMI input ports and the display to the single HDMI output port. The step people miss is ensuring all cables support 48Gbps bandwidth for 8K@60Hz or 4K@120Hz signals.

Will the IR remote or front button wear out and need replacement?

The IR remote uses a standard button-cell battery that will need replacing over time. The front physical button is a mechanical switch rated for long-term use and has no user-serviceable parts.

What is the first limitation I hit when running 4K@120Hz gaming sessions for hours?

The 48Gbps bandwidth ceiling is the hard limit. Sustained 4K@120Hz with HDR, VRR and ALLM uses the full spec, so cable quality and source compliance become the bottlenecks before the switch itself.
