Two-source HDMI switch

The WRIARICH TJ-A002 connects two HDMI sources to a single display and lets you swap between them with a front-panel button. It is built for users who need to share one monitor or projector between a desktop and a laptop, a console and a media player, or any pair of HDMI devices.

48 Gbps HDMI 2.1 bandwidth

The switch passes video up to 8K at 60 Hz and 4K at 120 Hz through its HDMI 2.1 interface, delivering a maximum data rate of 48 Gbps. This bandwidth figure is the deciding specification: if your sources and display require the full 48 Gbps link for uncompressed high-resolution signals, this unit supports it; if they need more, it will not.

Powered operation under continuous use

External power via the included USB-A-to-Micro-B cable is mandatory; without it the switch passes no signal at all. Once powered, the button toggles the active input in roughly one second and LED indicators confirm the selected port, so sustained switching sessions remain stable as long as the USB supply stays connected.

Questions about this item

What does the 48 Gbps bandwidth mean for my 8K display?

It carries the full 8K 60 Hz or 4K 120 Hz signal without compression, provided you use a certified HDMI 2.1 cable on every link.

How does the HDMI 2.1 interface limit what I can connect?

The switch passes up to 48 Gbps, so any source or display limited to an earlier HDMI version will run at its own maximum rate instead.

What do I need on my desk to mount or power this switch?

The unit is 5 inches long and requires the included USB-A-to-Micro-B cable plugged into a 5 V power source; without that power the switch will not pass a signal.
