What the LUOM HDMI 2.1 Bi-Directional Switch does

This LUOM switch handles HDMI 2.1 signals in two directions. It connects two source devices to one display, or one source to two displays, though only one output works at a time. It supports resolutions up to 8K at 60 Hz and 4K at 120 Hz, plus 1080p at 240 Hz. The aluminium housing is finished in black.

Installation and common issues

Plug the HDMI cables into the two ports and press the button to toggle between sources or displays. No external power supply is required. Problems usually arise when cables exceed ten metres or when a connected device does not fully support HDMI 2.1 bandwidth, causing handshake failures or dropped frames.

Who this suits and who should look elsewhere

The switch suits gamers and home-cinema users who need to share a single 8K or high-refresh 4K screen between a console and a PC, or who want to move one source between two rooms. It does not suit anyone who needs both outputs active simultaneously, or who requires more than two ports.

Questions about this item

How can I confirm the 8K@60Hz signal is passing through correctly after connecting my PS5?

Verify the display reports 8K@60Hz in its on-screen menu and check for Dolby Vision or HDR10 indicators while playing supported content.

What cables or accessories must I buy separately to use the 2-port bi-directional switch?

The unit includes the switch only; you need three HDMI 2.1 cables (two for sources, one for display) to run 2-in-1-out or 1-in-2-out configurations.

Should I choose this 2-port model or a larger switch for a PS5, Switch and Blu-ray player setup?

This model handles two sources only; if you need three devices connected simultaneously, select a switch with three or more input ports.
