Two-source HDMI switch for single display

This ESTONE TJ-A002 unit connects two HDMI sources to one display, letting you toggle between a console, media player or PC without swapping cables. It targets gamers and home-theatre users who need 8K or high-refresh 4K on a single screen.

48 Gbps bandwidth with 8K 60 Hz

The switch passes 8K at 60 Hz and 4K at 120 Hz through its 48 Gbps HDMI 2.1 path, so the decisive spec is whether your sources and cables can deliver that throughput. If your gear tops out at lower rates the switch remains compatible, but you will not gain the advertised resolution and refresh combinations.

USB-powered with push-button switching

A micro-USB cable in the box must be connected to a 5 V USB port for the switch to function; without external power no signal reaches the display. Press the select button to change inputs in about one second while LED indicators show the active port. The device is strictly two-in, one-out and cannot send one source to two displays.

Questions about this item

What does 48 Gbps bandwidth deliver on my screen?

It carries 8K at 60 Hz or 4K at 120 Hz with full colour depth, provided you use HDMI 2.1 cables and both source and display support those modes.

Which HDMI version does the switch use and what does it limit?

The switch is built to the HDMI 2.1 specification, capping throughput at 48 Gbps and enabling 8K 60 Hz and 4K 120 Hz when cables and devices also meet that standard.

What space and connections does the unit need to sit in my rack?

The black box measures about 5 inches across, has two HDMI inputs and one HDMI output on the rear, plus a Micro-USB port that must be connected to a 5 V USB power source for the switch to function.
