2-in-1 HDMI 2.1 Switch

The ESTONE TJ-A002 routes two HDMI 2.1 sources to a single display, supporting 7680 x 4320 at 60 Hz and 4096 x 2160 at 120 Hz with 48 Gbps bandwidth. It is built for users who need to toggle between a game console and a media player without swapping cables.

Sustained 48 Gbps throughput

The switch maintains the full 48 Gbps link during extended gaming or video sessions, provided a standard HDMI 2.1 cable is used and the included USB power cable is connected. Indicator LEDs confirm the active port, and signal switching completes in roughly one second.

Replaces manual cable swapping

This unit upgrades setups that currently require unplugging and replugging HDMI leads when changing sources. The jump is worthwhile for anyone running two 8K or high-refresh 4K devices into one screen who wants instant, powered switching without signal loss.

Questions about this item

Does the ESTONE TJ-A002 get hot or noisy when left powered all day?

The switch has no fan and draws 5 V from the included USB cable, so it runs silently and stays cool during continuous use.

What cables or power sources must I already have to use this 2-in-1-out switch?

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 for the Micro-B power cable.

Will the TJ-A002 pass 4K 120 Hz from my older console through to a new 8K TV?

Yes, the switch is backward compatible with earlier HDMI standards and supports 4K at 120 Hz as well as 8K at 60 Hz up to 48 Gbps.
