Two-port HDMI 2.1 switch for dual-source setups

This LUOM OZ8Q2B switch routes video and audio from two HDMI sources to a single display. It supports 8K resolution at 60 Hz and 4K at 120 Hz, plus lower resolutions up to 1080p at 240 Hz. A front button toggles between inputs with LED indication. The aluminium enclosure measures 5.91 by 2.36 by .79 inches and weighs 11.9 ounces.

Sustained 48 Gbps throughput with active power

The switch maintains the full 48 Gbps bandwidth required for 8K 60 Hz and 4K 120 Hz signals without frame drops or resolution scaling. A DC 5 V power cable is included; connecting it via the Micro USB port is recommended for stable operation during extended sessions. Backward compatibility with HDMI 2.0 and 1.4 ensures older sources remain functional at their native rates.

HDMI 2.1 cable length limits apply

HDMI 2.1's 48 Gbps signalling is sensitive to cable length; the manufacturer advises using certified Ultra High Speed HDMI cables for 8K 60 Hz and 4K 120 Hz output. Longer passive cables may force a fallback to lower resolutions or refresh rates. The switch itself adds no compression or latency, so the practical limit is the cable quality on both the input and output sides.

Questions about this item

Does the LUOM OZ8Q2B switch generate noticeable heat or draw much power when left running all day?

The switch is a passive aluminium unit with no fan, so it runs silently and produces negligible heat; it only requires the included 5 V DC power cable for stable 48 Gbps operation.

What cables or adapters must I already own to connect two sources and one display to this switch?

You need three HDMI cables — two to link your sources to the two HDMI inputs and one from the single HDMI output to your display — plus a USB power adapter for the supplied 5 V DC cable.

Will the OZ8Q2B work properly with my older HDMI 1.4 Blu-ray player and 1080p monitor?

Yes, the switch is backward compatible with HDMI 1.4, 2.0 and 2.0b, so an HDMI 1.4 source and a 1080p display will function at their native resolutions up to 240 Hz.
