4-port HDMI 2.1 8K switch

This LUOM TJ-A140 switch routes four HDMI 2.1 sources to a single display. It handles 8K at 60 Hz, 4K at 120 Hz and 1080p at up to 165 Hz with 48 Gbps bandwidth. An aluminium chassis and USB-C power keep the unit compact for desktop or living-room use.

Gamers and home-theatre users with several 8K

Buyers connecting multiple consoles, a PC and a media player to one TV or projector will benefit from instant IR or button switching. The switch is not bidirectional, so anyone needing one source sent to four displays should look elsewhere.

48 Gbps HDMI 2.1 bandwidth

The 48 Gbps link carries uncompressed 8K 60 Hz 4:4:4, HDR10+ and 12-bit colour without compression. If your display or cables cannot sustain this bandwidth, the switch will fall back to lower resolutions.

Questions about this item

How can I confirm the LUOM TJ-A140 is passing 8K@60Hz after connecting my sources and display?

Play an 8K@60Hz test pattern from a connected source; the switch passes HDMI 2.1 48Gbps bandwidth and HDCP 2.3, so the display should show the full resolution without dropouts.

What comes in the box with the LUOM TJ-A140 and which cables or power adapters must I provide?

The package includes the 4×1 HDMI 2.1 switch only; you must supply four HDMI 2.1 cables for the inputs, one HDMI 2.1 cable for the output, and a USB-C 5V/1A power source such as a USB port or wall adapter.

Which version of the LUOM TJ-A140 should I choose for a setup that needs 4K@120Hz gaming on multiple consoles?

The single TJ-A140 model already delivers 4K@120Hz, 1080P@144Hz/165Hz, HDR10+, and HDCP 2.3 across all four HDMI 2.1 inputs, so no alternate version is required.
