LUOM TJ-A125 3x1 HDMI 2.1 switch

This LUOM TJ-A125 is an HDMI 2.1 switch that routes three sources to one display. It suits anyone with a modern TV or monitor that has only a single HDMI 2.1 input but several 8K-capable devices. The switch handles 48Gbps bandwidth and supports resolutions up to 8K at 60Hz and 4K at 120Hz. All three input ports sit on the same side for a tidy desktop layout.

Replaces manual cable swapping

The switch removes the need to unplug and reconnect HDMI cables when changing between a console, a streaming box and a PC. A single button selects the active source and an LED shows which port is live. The upgrade is worth it when you run multiple 8K or high-refresh 4K sources and want instant switching without signal degradation. It is not for setups that require simultaneous output to multiple displays.

Fits a single-display HDMI 2.1 chain

Connect each source with an HDMI 2.1 cable to the three inputs, then run one HDMI 2.1 cable from the output to the display. The aluminium shell dissipates heat without external power. The unit passes Dolby Atmos, DTS Digital and Dolby Digital audio formats through to the display or receiver. It does not add extra outputs for multi-room or capture workflows.

Questions about this item

What are the physical dimensions of the LUOM TJ-A125 switch?

The unit measures 12 by 6 by 0.08 inches and weighs 1.2 ounces, so it fits easily on a desk or shelf without blocking adjacent ports.

How do I connect and switch between sources on the TJ-A125?

Plug up to three HDMI 2.1 sources into the three input ports and one display into the single output port, then press the front button to cycle inputs; the indicator light shows the active port.

Will I need to replace the cables later to keep 8K 60 Hz performance?

For 8K at 60 Hz or 4K at 120 Hz the supplier recommends certified HDMI 2.1 cables rated for 48 Gbps; standard older cables may limit resolution or refresh rate.
