Four-input HDMI 2.1 switch

The LUOM TJ-A140 routes four HDMI 2.1 sources to one display, supporting 8K at 60 Hz and 4K at 120 Hz over a 48 Gbps link. It is built for gamers and home-theatre users who need to swap between consoles, PCs or media players without re-plugging cables. The aluminium chassis keeps the unit compact and cool. Buyers who need bi-directional switching or more than four inputs should look elsewhere.

Remote and front-panel control

An IR remote lets you change the active input from the sofa while a push button on the chassis provides local switching. A USB-C port supplies 5 V at 1 A from any convenient USB power source, so no dedicated wall wart is required. An IR extension jack allows the receiver to be placed out of sight. The package contains only the switch itself; cables are not included.

48 Gbps bandwidth ceiling

The single specification that decides fit is the 48 Gbps HDMI 2.1 bandwidth, which enables 8K 60 Hz, 4K 120 Hz and 1080p at 144 Hz or 165 Hz with HDR10+, 3D and HDCP 2.3. If your sources or display demand higher throughput or features such as DSC, this switch will not pass them.

Questions about this item

Will the USB-C 5V/1A power supply need replacing if the port wears out?

The switch draws power from any USB-C source supplying 5V/1A so you can swap the cable or adapter without opening the aluminium chassis.

What bandwidth ceiling appears first when running 8K60 or 4K120 continuously?

The HDMI 2.1 link is rated at 48Gbps, which is the hard limit for uncompressed 8K60 or 4K120 signals.

Does the aluminium shell stay cool during all-day 48Gbps throughput?

The passive aluminium alloy chassis dissipates heat from the 48Gbps HDMI 2.1 circuitry without a fan, so it runs silently.
