WRIARICH OZQ3-1 3×1 HDMI video switch 4K@60Hz black

3-Port HDMI 2.0 Switch for 4K@60Hz Displays

This WRIARICH OZQ3-1 unit connects three HDMI 2.0 sources to a single 4K display running at 60 Hz. It suits home-theatre owners, gamers or office users who need to alternate between a console, a streaming box and a PC without swapping cables. The switch passes HDR video at RGB 4:4:4 and 36-bit deep colour, plus compressed audio formats such as Dolby Atmos and DTS Digital.

Plug-and-Play Installation with IR Remote

No drivers or software are required; connect the three inputs, the output and the included 5 V power adapter, then select sources via the button on the unit or the supplied infrared remote. The aluminium enclosure aids heat dissipation. Ensure all cables are fully seated and the power LED is lit; a loose HDMI plug or an unpowered switch are the most common causes of a blank screen or handshake failure.

HDMI 2.0 Bandwidth and Cable-Length Limits

The switch operates at the HDMI 2.0 maximum of 18.5 Gbps (600 MHz pixel clock), so 4K@60Hz 4:4:4 signals demand certified Premium High Speed cables kept as short as practical — long runs often drop to 4K@30Hz or lose HDR. HDCP 2.2 is supported with backward compatibility to 1.4, but protected 4K streams will not pass through displays or repeaters that only implement earlier HDCP versions.
