3-input HDMI 2.1 switch for 8K displays

The LUOM TJ-A125 connects three HDMI 2.1 sources to a single 8K-capable display. It supports 8K at 60 Hz and 4K at 120 Hz with a 48 Gbps bandwidth ceiling. Gamers and home-theatre users can toggle between a console, a streaming box and a PC without swapping cables.

One-button switching with side-mounted ports

All three inputs and the output sit on the same face, keeping cables tidy on a desk or rack. A front-panel button cycles the active input and an LED shows which port is live. The aluminium chassis passively dissipates heat, so no external power supply is required for typical runs.

48 Gbps bandwidth decides 8K@60 Hz support

The switch passes the full 48 Gbps HDMI 2.1 data rate, enabling uncompressed 8K at 60 Hz and 4K at 120 Hz. If your source or display tops out at HDMI 2.0 bandwidth, the unit falls back to 4K at 60 Hz automatically. Buyers needing more than three simultaneous inputs should look at a larger matrix switcher.

Questions about this item

How can I confirm the LUOM TJ-A125 is passing 8K@60Hz or 4K@120Hz after connecting my sources and display?

The front-panel indicator LED shows which of the three HDMI 2.1 inputs is active; verify on your display's info menu that it reports 8K at 60 Hz or 4K at 120 Hz, and use certified 48 Gbps cables for those modes.

What comes in the box with the LUOM TJ-A125 and do I need to buy anything else to use it?

The package includes only the 3-in-1-out switch unit; you must supply three HDMI 2.1 cables for the sources and one HDMI 2.1 cable for the display, plus any power adapters your source devices require.

The LUOM TJ-A125 is listed as a single 3-port model — are there other versions or capacities I should consider?

The TJ-A125 is offered only as a 3-input, 1-output HDMI 2.1 switch supporting 48 Gbps bandwidth; no other port counts or capacity variants exist for this series.
