Connect two sources to one display

This ESTONE TJ-A002 HDMI 2.1 switch routes signals from two source devices to a single screen or projector. It supports resolutions up to 7680 x 4320 at 60 Hz and 4096 x 2160 at 120 Hz with a maximum bandwidth of 48 Gbps. The unit requires external power via the included USB A to Micro B cable to operate. A front button toggles between inputs and indicator lights show the active port.

Ideal for dual-console setups.

Gamers or professionals who alternate between a PS5, Xbox, TV box or PC on one 8K or high-refresh 4K display will find this switch convenient. It is unsuitable for anyone needing to send a single source to multiple displays simultaneously because the architecture is strictly two inputs to one output. Users without a nearby USB power source should also look elsewhere since the switch cannot function unpowered.

48 Gbps bandwidth enables 8K 60 Hz and 4K 120 Hz

The 48 Gbps rating is the single specification that determines whether this switch can transport your target resolution and refresh rate without compression. If your source and display require the full 8K 60 Hz or 4K 120 Hz signal path, this bandwidth ceiling is the deciding factor. Lower-bandwidth switches will not support those modes.

Questions about this item

Does the 48 Gbps bandwidth limit how long I can run 8K at 60 Hz continuously?

The switch is rated for 48 Gbps and supports 8K at 60 Hz, so sustained use at that resolution stays within its specified bandwidth ceiling.

How much heat or fan noise does the unit produce when powered all day via the USB cable?

The device has no fan and draws power only from the included USB‑A to Micro‑B cable, so it runs silently with minimal heat during extended operation.

Which cables and power source must I already have to connect two sources to one display?

You need two HDMI 2.1 cables for the sources, one HDMI 2.1 cable for the display, and a USB‑A port or charger to supply 5 V power through the supplied Micro‑B cable.
