Three-input HDMI 2.1 switch

The LUOM TJ-A125 is a new 3-port HDMI 2.1 switch that routes three source devices to a single display. It suits setups with a console, media streamer and PC sharing one 8K or high-refresh 4K screen.

Sustained 48 Gbps throughput

All three inputs and the output run at the full HDMI 2.1 48 Gbps rate, so extended gaming or streaming sessions at 8K 60 Hz or 4K 120 Hz maintain bandwidth without throttling. The aluminium shell dissipates heat during continuous operation.

One-button source selection

A single front button cycles through the three inputs while LED indicators show the active port. No remote or auto-switching is provided, so users who want hands-free switching need a different solution.

Questions about this item

Does the LUOM TJ-A125 run warm or make any noise when left on all day?

The aluminum alloy shell provides passive heat dissipation, and the unit has no fan, so it stays silent and only slightly warm during continuous use.

What cables or power supply do I need before the LUOM TJ-A125 will switch my sources?

You need three HDMI 2.1 cables for the inputs and one for the output; no external power adapter is required because the switch draws power from the connected sources.

Will my older 1080p Blu-ray player and 4K 60 Hz monitor work through this 8K 60 Hz switch?

Yes, the switch is backward compatible with earlier HDMI standards, so 1080p and 4K 60 Hz signals pass through without any extra setup.
