8K Bi-Directional HDMI 2.1 Switch

The LUOM OZ8AB is a compact HDMI 2.1 switcher and splitter that handles 8K at 60 Hz and 4K at up to 144 Hz. It routes signals between two sources and one display, or one source and two displays, with a maximum bandwidth of 48 Gbps. A supplied DC 5 V power adapter ensures stable operation for high-resolution content.

Gamers and multi-source setups

Console owners running 4K at 120 Hz on Xbox Series X or PS5 will benefit from the high refresh support. Home-theatre users who need to toggle between two 8K sources on a single screen also fit this device. It is not for installations requiring simultaneous dual-display output or automatic source detection.

Manual push-button switching

Source or display selection is performed by a physical button on the unit; there is no auto-switching function. Switching high-power devices can take three to six seconds to complete the handshake. This behaviour determines whether the workflow suits your environment.

Questions about this item

Will this switch pass 8K at 60Hz and 4K at 120Hz from my older HDMI 2.0 sources?

The switch is backward compatible with earlier HDMI standards, so it will pass whatever resolution and refresh rate the source and display negotiate, up to its 48Gbps limit.

How can I confirm the switch is delivering 48Gbps bandwidth after I connect it?

There is no on-device indicator for bandwidth; verify the link by checking that the display shows the expected resolution and refresh rate and that HDR, VRR and chroma settings are active in the source menu.

What comes in the box and do I need to buy HDMI cables separately?

The package includes the 8K HDMI AB switch, a DC 5V power cable and a user manual; HDMI cables are not included and must be purchased separately.
