LUOM OZ8Q2B 8K HDMI 2.1 Switch 2x1 48Gbps

2-in-1 HDMI 2.1 switch for dual-source setups

The LUOM OZ8Q2B routes two HDMI inputs to a single display, supporting 8K at 60 Hz and 4K at 120 Hz. It suits gamers and professionals who alternate between a console, PC or streaming device without swapping cables. The aluminium chassis houses a directional 2×1 topology that preserves full 48 Gbps bandwidth. Buyers who need simultaneous multi-monitor output or more than two sources should look elsewhere.

Push-button switching with optional USB power

A single selector button toggles the active port while LED indicators show the live input. The unit is plug-and-play for most 1080p and 4K sources, but the manufacturer advises connecting the included DC 5 V Micro-USB cable for stable 8K or high-refresh 4K signals. Without external power, marginal cables or long runs may cause drop-outs or handshake failures. No software or driver installation is required.

Bandwidth ceiling and cable-length limits

The HDMI 2.1 interface caps throughput at 48 Gbps, enabling 7680×4320 at 60 Hz, 4K at 120 Hz, 2K at 144 Hz and 1080p at 240 Hz. It remains backward compatible with HDMI 2.0b, 2.0a, 2.0 and 1.4 sources. Achieving the highest resolutions demands certified Ultra High Speed HDMI cables; longer passive cables can exceed the electrical budget and force a fallback to lower modes. The switch itself adds no latency or compression.
