What this switch does

The LUOM HDMI 2.1 bi-directional switch connects two HDMI sources to one display or routes one source between two displays. It supports 8K at 60 Hz and 4K at up to 120 Hz, plus 1080p at 240 Hz. The unit is plug-and-play with no external power required.

Thermals, noise and power

The aluminium housing passively dissipates heat so the switch runs silently. No fan or power adapter is needed; it draws all required power from the connected HDMI devices. Nickel-plated contacts reduce signal loss across the 48 Gbps link.

The deciding specification

The single port count of two HDMI sockets defines whether this switch fits your setup. It handles one active path at a time and cannot drive two displays simultaneously. Buyers needing simultaneous dual-output or more than two sources should look elsewhere.

Questions about this item

How do I install the LUOM HDMI 2.1 Bi-Directional Switch and what step do people often miss?

Connect the HDMI sources and display using standard HDMI 2.1 cables, then press the button to select the active port; the step people miss is ensuring the total cable length does not exceed 3M for 8K@60Hz signals.

What maintenance or replacement will this switch need later?

No routine maintenance is required; if signal dropouts appear, replace the HDMI 2.1 cables first, as the switch itself has no user-serviceable parts and draws power from the connected devices.

What is the first limit I will hit under sustained 4K 120Hz gaming use?

The 48Gbps bandwidth ceiling caps you at 4K@120Hz with 4:4:4 chroma; pushing 4K@144Hz or 4K@165Hz forces chroma subsampling to 4:2:2 or 4:2:0.
