Four-input HDMI 2.1 switch for 8K

The LUOM TJ-A140 is a directional 4-in-1-out HDMI 2.1 switch built for users who run multiple 8K 60 Hz or 4K 120 Hz devices such as a desktop PC, laptop, Xbox or PlayStation 5 into a single display or projector. It handles 48 Gbps bandwidth, HDR10+ and deep colour up to 12-bit with 4:4:4 chroma, so the signal stays intact for gaming and home-theatre use. An included IR remote and front-panel button let you change sources without leaving the sofa.

Replaces manual cable swapping

If you currently unplug HDMI cables to move between four sources, this unit removes that wear on ports and cables. The step up from an 18 Gbps HDMI 2.0 switch is only worthwhile when at least one source outputs 8K 60 Hz, 4K 120 Hz or 1080p 144 Hz and 165 Hz signals that need the full 48 Gbps path. For setups that never exceed 4K 60 Hz the extra bandwidth brings no visible benefit.

Fits into a rack or desk with an aluminium shell

The compact aluminium chassis measures 12 by 6 by 0.08 inches and draws 5 V 1 A from any USB-C port on a TV, monitor or charger, so no separate power brick is required. Four HDMI 2.1 inputs and one HDMI 2.1 output are all female; an IR extension jack lets you hide the box behind a display while keeping remote control working. It does not support bi-directional operation, so it cannot send one source to four screens.

Questions about this item

How much clearance does the 12 x 6 x .08 inch aluminium chassis need behind a TV or monitor?

The switch measures 12 x 6 x .08 inches and weighs 1.2 ounces, so it fits in tight spaces behind a display; allow a few centimetres for the four HDMI cables and the USB-C power lead.

Which step do users often miss when connecting the USB-C 5V/1A power port?

Plug the USB-C cable into a 5V/1A source before linking the four HDMI 2.1 inputs and the single HDMI 2.1 output; the switch will not pass 8K 60Hz or 4K 120Hz signals without external power.

Will the IR remote sensor need cleaning or the USB-C port replacing over time?

The IR extension channel and remote require no scheduled maintenance; the USB-C power port is rated for standard insertion cycles, and the aluminium chassis has no moving parts to wear out.
