Three-port HDMI 2.1 switch

The Fosmon HD8234FG connects three HDMI sources to one display and lets you change the active input with a button on the unit or the supplied IR remote. It handles 48Gbps bandwidth for 8K resolution at 60Hz and is backward compatible with earlier HDMI versions. A USB-C cable is included for power; a 5V USB adapter is required but not supplied.

Best for multi-source setups

This switch suits anyone who wants to run a console, a streaming box and a PC through a single screen without swapping cables. It does not support a single source feeding two displays, so buyers needing a 1-in-2-out splitter should look elsewhere. HDMI cables longer than two metres may degrade the 8K signal.

48Gbps bandwidth ceiling

The 48Gbps link is the specification that determines whether 8K at 60Hz, 4K at 120Hz or 1080p at 240Hz can be delivered without compression. Both the source devices and the display must support HDMI 2.1 and HDCP 2.3, and certified ultra-high-speed cables are required to reach the rated performance.

Questions about this item

Does the Fosmon HD8234FG generate noticeable heat or noise when powered continuously via USB-C?

The aluminium chassis acts as a passive heatsink, so the switch runs silently and stays cool during all-day use with the supplied USB-C cable and a 5 V adapter.

What power source must I already have to operate the HD8234FG?

A 5 V USB power adapter with a USB-C port is required; the box includes only the USB-C charging cable, not the adapter itself.

Will my older 1080p 60 Hz monitor work through this 48 Gbps HDMI 2.1 switch?

Yes, the switch is backwards compatible and will pass 1920 x 1080 at 60 Hz without any extra setup.
