ESTONE TJ-A002 HDMI 2.1 Switch

The ESTONE TJ-A002 is an HDMI 2.1 switch that routes two source devices to a single display. It supports video resolutions up to 4096 x 2160 at 60 Hz and 4K at 120 Hz with a maximum bandwidth of 48 Gbps. The unit is brand new and includes a USB-A to Micro-B cable for required external power.

Gamers and multi-source setups

This switch suits users who need to toggle between two consoles or media players on one 8K-capable screen. It is not for buyers who want to send one source to two displays, as the device only operates in a 2-in-1-out direction. It also cannot function without the supplied USB power cable connected.

Simple button-operated installation

Setup requires connecting both HDMI sources, the display, and the USB power cable before pressing the select button to swap signals. The indicator lights confirm the active port within one second. The most common issue is a blank screen caused by forgetting to plug in the USB power lead.

Questions about this item

Do I need a USB power source to run the ESTONE TJ-A002 switch?

Yes, the included USB A to Micro B cable must be connected to a 5 V USB port; without external power the switch will not pass any signal.

Will the switch work with my existing HDMI 2.0 cables and 4K 60 Hz monitor?

The unit is backward compatible with earlier HDMI standards, so HDMI 2.0 cables and a 4K 60 Hz display will function, though 8K 60 Hz and 4K 120 Hz require HDMI 2.1 cables.

How can I confirm the active input after pressing the select button?

Indicator lights on the switch show which of the two source ports is currently routed to the display.
