Three-input 8K HDMI 2.1 switch

The LUOM TJ-A113 routes video and audio from three HDMI 2.1 sources to a single display. It supports 8K at 60 Hz and 4K at 120 Hz with 48 Gbps bandwidth, Dynamic HDR, VRR and full chroma sampling. The aluminium shell keeps all ports on one side for a tidy desktop. An IR remote and front-panel button let you change the active input instantly.

Check cables and power first

Use certified HDMI 2.1 cables no longer than 10 feet to maintain 8K 60 Hz signal integrity. The switch draws power through a USB-C port; connect the supplied cable when driving power-hungry sources such as consoles or high-refresh-rate PCs. Without external power the unit may drop the signal or fail to switch. Verify each source device outputs a standard HDMI 2.1 signal compatible with the listed resolutions.

Fits between sources and one screen

Three HDMI 2.1 inputs accept consoles, streaming sticks, Blu-ray players or computers. One HDMI 2.1 output feeds an 8K TV, high-refresh monitor or projector. The compact 8 by 5 by 0.03 inch enclosure sits discreetly on a desk or media shelf. It frees up display ports by consolidating three devices into one input, but it does not split one source to multiple screens.

Questions about this item

Does the LUOM TJ-A113 include HDMI cables or a power adapter in the box?

The package contains the 3-in-1-out switch only. You must supply three HDMI 2.1 cables for the sources and one for the display, plus a USB-C power cable and charger if you connect power-hungry devices.

Which resolution and refresh-rate combination should I pick for a PlayStation 5?

The switch handles 4K at 120 Hz and 8K at 60 Hz. For PS5 gaming, select 4K 120 Hz in the console settings to match the switch's 48 Gbps bandwidth limit.

What does the 48 Gbps bandwidth mean when I plug the switch into my 8K TV?

It is the maximum data rate of the HDMI 2.1 link. With certified cables under 10 feet, it carries 8K 60 Hz HDR, VRR and 4:4:4 chroma without compression.
