Four-Port 8K HDMI 2.1 Switch

The LUOM TJ-A140 is a directional 4-in-1-out HDMI 2.1 switch built for gaming and home-theatre setups. It routes four HDMI 2.1 sources to a single display at up to 8K@60Hz or 4K@120Hz with 48Gbps bandwidth. An aluminium chassis houses the female ports, and a USB-C 5V/1A input powers the unit. An IR remote and front-panel button provide switching control.

Suits multi-source 8K or high-refresh 4K users

Buyers with up to four HDMI 2.1 devices such as a PC, console, streamer or Blu-ray player can share one 8K TV, monitor or projector. It supports HDR10+, 3D, HDCP 2.3 and compressed audio formats including Dolby Atmos and DTS-HD. Users needing bi-directional routing, more than four inputs or HDMI 2.0-only sources without 2.1 features should consider other options.

Fits between sources and one display

Connect each source to the four HDMI 2.1 inputs — Input 1 sits on one side, Inputs 2-4 and the output on the other — then run a single HDMI 2.1 cable to the display. The USB-C power port draws 5V/1A from a nearby USB charger or TV port, freeing a mains socket. The IR extension channel allows remote operation when the switch is tucked behind equipment.

Questions about this item

What source devices and cables must I already have to use the four HDMI 2.1 inputs?

You need up to four HDMI 2.1 source devices such as a PC, Xbox, PS5 or streaming stick, plus four HDMI 2.1 cables rated for 48 Gbps, and a USB-C power adapter that delivers 5 V / 1 A for the switch.

Will my older 1080p 60 Hz monitor work if I keep it connected to the single HDMI 2.1 output?

Yes, the switch passes 480p, 576p, 720p and 1080p signals through the HDMI 2.1 output, so a legacy 1080p 60 Hz display will show the selected source without any extra setup.

How can I confirm the switch is passing 8K 60 Hz or 4K 120 Hz correctly after I connect everything?

Use the IR remote or front button to select each input, then check the display’s on-screen information for 8K at 60 Hz or 4K at 120 Hz, and verify HDR10+ and 12-bit deep colour are active.
