4×2 HDMI Matrix Switch

The WRIARICH OZJ2-1 routes four HDMI sources to two displays with independent output selection. Each output can show any input, so two rooms or screens share the same sources without cable swapping. An IR remote and front-panel buttons provide switching control. The unit supports 4K resolution at 60 Hz with 18 Gbps bandwidth.

Installers needing flexible 4K distribution

Home cinema owners who want to send a games console, streamer and Blu-ray player to both a projector and a TV will find the matrix useful. Installers requiring HDCP 2.2 compliance for protected 4K content are covered. Buyers who need more than four inputs or more than two simultaneous outputs should consider a larger matrix.

ARC audio return on Input 4

The switch implements Audio Return Channel between Input 4 and Output 1, letting a connected TV send sound back to an ARC soundbar or receiver on that input pair. This single audio path simplifies cabling when the main display handles smart-TV apps. Other inputs pass standard audio formats including DTS HD and Dolby TrueHD.

Questions about this item

How do I connect the four sources and two displays to the matrix switch, and which step is often missed?

Connect up to four HDMI sources to the input ports and two displays to the output ports, then power the unit with the included adapter; the step often missed is setting the EDID mode via the front‑panel buttons so each source negotiates the correct 4K@60Hz signal.

What maintenance or replacement will the IR remote need over time?

The IR remote runs on a standard button‑cell battery that will need replacing when the range drops; no other user‑serviceable parts are inside the switch itself.

At what video bandwidth does the switch hit its limit during sustained 4K HDR playback?

The 18Gbps HDMI 2.0b path is the first bottleneck; sustained 4K@60Hz HDR streams use the full bandwidth, so longer cables or additional conversions may cause signal drop‑outs.
