Bi-Directional HDMI 2.1 Switch

The ESTONE TJ-A041 is an aluminum HDMI 2.1 switch that operates in two modes. It connects two sources to one display or one source to two displays. Gamers and home-theatre users can toggle between a console, PC or streaming box without swapping cables.

Replaces Manual Cable Swapping

It removes the need to physically change HDMI leads when moving between a PS5, Xbox Series X, Apple TV or similar 4K 120 Hz sources. The jump is worth it when you run multiple 8K 60 Hz or 4K 120 Hz devices on a single 8K monitor or TV and want instant switching with dual status LEDs.

HDMI 2.1 48 Gbps Bandwidth Limit

The PI3HDX1221 chip delivers 48 Gbps throughput, capping resolution at 8K 60 Hz or 4K 120 Hz. Connected HDMI cables must not exceed 3 metres per leg. Only one output displays at a time, and the micro-USB power input is required when source power is insufficient.

Questions about this item

What size HDMI cables fit the two HDMI 2.1 inputs and the single HDMI 2.1 output on this switch?

Standard HDMI plugs fit the two inputs and one output; keep each cable run at 3 metres or less for reliable 48Gbps transmission.

How do I power the unit and switch between 2-in-1-out and 1-in-2-out modes?

Plug the included DC 5V micro-USB cable into the power port, then press the button to toggle modes; the dual LEDs show which port is active.

How often should I check the micro-USB power connection for long-term 8K@60Hz use?

Inspect the micro-USB cable and port every few months; the chip runs 14 overheat checks per second, so a loose power lead is the main failure risk.
