What this switch does

This bidirectional HDMI switch routes signals between two sources and one display, or one source and two displays. Only one output is active at a time. It is designed for setups that need manual source selection without extra power supplies or drivers.

Passive operation and signal limits

The unit draws power from the HDMI connection itself and runs silently with no fan. It supports bandwidth up to 3.4 Gbps and passes 1080p, 3D and 4K x 2K signals when used with HDMI 2.0 cables. With HDMI 1.4 cables the source must be set to 1920 x 1080.

Replaces manual cable swapping

This switch removes the need to unplug cables when changing between a console, PC or media player on a single screen, or when sending one source to either of two monitors. It does not drive two displays simultaneously, so it is not suited for dual-monitor extension.

Questions about this item

How do I install the SMA HDMI bidirectional switch and which step do people often get wrong?

Connect all devices with HDMI cables, then press the button on top to select the active source or display; the step people miss is using HDMI 2.0 cables for 4K sources, otherwise the signal falls back to 1080P.

What maintenance or replacement will this switch need later?

No firmware or driver updates are required; only the HDMI cables may need replacing if they degrade or if you upgrade to a 4K source that demands HDMI 2.0 certified cables.

What limit appears first during sustained use of this switch?

The 3.4Gbps bandwidth ceiling limits continuous throughput to 1080P at 60Hz; 4K signals at 4096x2160 exceed this rate and will not pass through reliably.
