WRIARICH OZ8AB 8K HDMI 2.1 Switch

This new WRIARICH OZ8AB is a bi-directional HDMI 2.1 switcher and splitter for users who need to route 8K or high-refresh 4K signals between sources and displays. It serves gamers and home-theatre enthusiasts connecting consoles or streamers to a single screen, or one source to two displays. Buyers who require automatic source detection or simultaneous dual-monitor output should look elsewhere.

48 Gbps bandwidth and 7680x4320 resolution headroom

The switch handles 8K at 60 Hz and 4K at 120 Hz through its 48 Gbps pathway, supporting Dynamic HDR, VRR and full chroma subsampling modes. It provides ample headroom for current-generation consoles and 8K media players. The bandwidth ceiling means it cannot carry uncompressed signals beyond the stated 8K 60 Hz or 4K 120 Hz limits.

HDMI 2.1 interface practical limits

Manual switching takes 3 to 6 seconds on high-power devices and both outputs cannot display at the same time in splitter mode. The unit requires the supplied DC 5 V power cable to operate. Reliable 8K 60 Hz and 4K 120 Hz transmission demands certified ultra-high-speed HDMI cables no longer than 3 metres, which are not included.

Questions about this item

Will this switch pass 8K at 60 Hz from my new console to an older 4K display without downscaling issues?

The switch handles up to 7680x4320 at 60 Hz and is backward compatible with earlier HDMI versions, so it will pass the signal through; the display itself determines the final resolution.

How can I confirm the OZ8AB is delivering 48 Gbps bandwidth after I connect everything?

Check the source device’s info menu for 8K at 60 Hz or 4K at 120 Hz with Dynamic HDR and 4:4:4 chroma — those modes require the full 48 Gbps link.

Does the package include HDMI cables or do I need to buy certified 2.1 cables separately?

The box contains the switch, a DC 5 V power cable and a user manual; HDMI cables are not included and the maker recommends certified 2.1 cables no longer than 3 metres for 8K or 4K 120 Hz.
