What this switch does

The SMUGDESK 8K Bi-Directional HDMI Switch Splitter lets you route two HDMI sources to one display or mirror one source across two screens. It supports 8K at 60Hz, 4K at 120Hz and 4K at 144Hz through its 48Gbps bandwidth. Gamers and home-cinema users can connect consoles, streaming sticks or PCs without swapping cables.

Installation and common issues

The unit is plug-and-play with no drivers or external power required; a manual button toggles between modes. Use certified ultra-high-speed HDMI cables to reach the rated resolutions and refresh rates. Long or low-quality cables can cause signal drop-outs, flicker or failure to handshake at 8K or high-refresh 4K.

Capacity and headroom

The 48Gbps path handles 8K at 60Hz and 4K at 144Hz without compression. It will not pass higher refresh rates or future formats that exceed the HDMI 2.1 bandwidth ceiling. The splitter function mirrors the same image to both outputs; it cannot drive two different content streams simultaneously.

Questions about this item

How can I confirm the switch is delivering 8K at 60Hz after connecting my PS5?

The PS5 display settings will show 8K resolution at 60Hz when the link is active; the front LED indicates which port is selected and a stable picture with no flicker confirms the 48Gbps path is working.

What comes in the box and do I need extra HDMI cables?

The package includes the switch unit only; you must supply three HDMI 2.1 cables — two for sources and one for the display — to reach the rated 48Gbps bandwidth.

Should I choose this 2-in-1 model or a larger 4-port switch for my PS5, Xbox and Fire Stick?

This model handles two sources to one screen or one source mirrored to two displays; if you need three or more sources active simultaneously, a 4-port switch would be required.
