Three-port HDMI 2.1 switch for 8K displays

The LUOM TJ-A210 connects three HDMI 2.1 sources to a single 8K display at 60 Hz or 4K at 120 Hz. It passes 48 Gbps bandwidth with HDR, Dolby Vision and compressed audio formats including Dolby Atmos and DTS-HD. A supplied IR remote and front-panel button let you change inputs without leaving your seat. The unit is powered by an included DC 5 V cable for stable operation.

Ideal for multi-console living rooms.

Gamers with a PS5, Xbox Series X and a streaming box can share one high-refresh display without swapping cables. Home-theatre owners who need Dolby Atmos pass-through to an AV receiver will benefit from the supported audio formats. Buyers who must show two sources simultaneously or route one source to multiple screens should consider a matrix switch instead. The switch does not add HDMI ports to a PC graphics card.

Fits behind a TV or on a shelf.

At 12 by 6 by 0.08 inches and 1.2 ounces the aluminium enclosure tucks discreetly behind a display or inside a media cabinet. Each of the three inputs and the single output uses a standard female HDMI 2.1 connector, so existing certified cables up to 5 metres work without adapters. The required 5 V power lead can plug into a TV USB port or the bundled wall wart, leaving no separate power brick on the floor.

Questions about this item

What HDMI cables and source devices do I need to connect to the three HDMI 2.1 inputs?

You need three HDMI 2.1 source devices such as a PC, PS5, Xbox Series X, Roku or Blu-ray player, plus three HDMI cables to plug into the switch inputs.

Will the switch pass 4K@120Hz and HDR from my older HDMI 2.0 console through the HDMI 2.1 output?

Yes, the switch is backward compatible with HDMI 2.0 and HDCP 1.4, so 4K@60Hz, HDR and 1080p signals from older consoles pass through to the display.

How can I confirm the switch is delivering 8K@60Hz or 4K@120Hz to my display after setup?

Check the display on-screen information or settings menu — it should report 8K at 60 Hz or 4K at 120 Hz with HDR active when playing compatible content.
