Bi-directional HDMI 2.1 switch for two sources

The LUOM OZQ8AB3 routes two HDMI sources to one display or one source to two displays without simultaneous output. It handles 8K at 60 Hz, 4K at 120 Hz and 1080p at 240 Hz with 48 Gbps bandwidth. The aluminium chassis measures 5.91 by 2.36 by 0.79 inches and weighs 11.9 ounces. A remote control and USB-C power cable are included.

Sustained 8K60 and high-refresh 4K throughput

The switch maintains 48 Gbps across long sessions with no added latency or quality loss. Maximum reliable cable reach is 1.5 metres for 8K, 3 metres for 4K and 8 metres for 1080p. VRR and Dynamic HDR pass through unchanged. HDCP 2.3 compliance keeps protected content flowing without handshake drops.

Passive cooling and bus-powered operation

No fan or external power brick is required; the unit draws power from the USB-C port. The aluminium body dissipates heat silently during continuous 8K60 or 4K120 use. Power draw stays low enough for standard USB ports. The remote uses two AAA batteries, which are not supplied.

Questions about this item

Does the LUOM OZQ8AB3 draw extra power or generate heat when left on 24/7?

It runs without an external power supply, so it adds no measurable heat or power draw during continuous use.

What cables and batteries must I supply myself before the switch works?

You need two HDMI 2.1 cables for the sources and two AAA batteries for the IR remote; the switch includes only a short USB-C cable for optional power.

Will my older 1080P@240Hz monitor work through this HDMI 2.1 switch?

Yes, the switch is backward compatible down to 1080P@240Hz, so legacy displays connect without issues.
