8K Bi-Directional HDMI Switch Splitter

The WRIARICH OZ8AB is an 8K bi-directional HDMI switch splitter that functions as a 2 in 1 out switcher and a 1 in 2 out splitter. It suits users who need to share one display between two sources or send one source to two displays manually. It does not suit buyers who need automatic switching or simultaneous output on both displays.

Thermals, Noise and Power Draw

The unit is powered by an external DC 5V charger included in the package. It has no internal fan, so it runs silently and adds negligible heat to a setup. Its compact dimensions of 5.91 x 2.36 x 0.79 inches and weight of 11.9 ounces keep the footprint small.

Behaviour Under Sustained Load

The switch supports 48Gbps bandwidth and maximum resolutions of 7680x4320 at 60Hz, maintaining signal integrity for 8K 60Hz and 4K 120Hz content during extended sessions. Manual switching may take 3-6 seconds for high-power devices. Using certified HDMI 2.1 cables under 3 metres ensures stable performance over long periods.

Questions about this item

How do I install the OZ8AB switch and which step do people miss?

Connect each source to the two HDMI inputs, the display to the single HDMI output, then plug in the supplied DC 5V charger; the step often missed is powering the unit before switching sources.

What maintenance or replacement will the OZ8AB need later?

No user-serviceable parts exist; only the external DC 5V power cable or HDMI cables may need replacement if they become damaged.

What limit appears first during sustained 8K 60Hz use on the OZ8AB?

The 48Gbps bandwidth ceiling and the 3 metre cable-length recommendation for 8K 60Hz signals are the first constraints encountered.
