3-Port HDMI 2.1 Switch for 8K Displays

The ESTONE TJ-A210 connects three HDMI 2.1 sources to a single 8K-capable display. It handles 8K resolution at 60 Hz and 4K at 120 Hz with a 48 Gbps bandwidth ceiling. The unit supports compressed audio formats including Dolby Atmos and DTS digital. A compact black enclosure measuring 12 by 6 by 0.08 inches weighs 1.2 ounces.

Passive Operation with External Power

The switch draws power from an included DC 5 V cable rather than relying on bus power from connected devices. No internal fan or active cooling is present, so operation is silent. Typical power consumption remains low because the device only routes signals without transcoding. The supplied remote control and front-panel button both change the active input without interrupting the video signal.

Sustained 8K Signal Integrity

Under continuous 8K 60 Hz or 4K 120 Hz throughput the link maintains full 48 Gbps bandwidth without compression artefacts. HDCP 1.4 and HDMI 2.0 backward compatibility ensure stable handshakes during long viewing sessions. Dynamic HDR, VRR and chroma sub-sampling modes 4:2:0, 4:2:2 and 4:4:4 are preserved across input changes. The directional architecture prevents signal degradation when only one source is active at a time.

Questions about this item

How do I install the ESTONE TJ-A210 switch and what step is often missed?

Connect up to three HDMI 2.1 sources to the three input ports and one display to the single output, then plug the included DC 5 V power cable into the USB-C power input; the step often missed is powering the unit, which is required for 48 Gbps bandwidth at 8K 60 Hz or 4K 120 Hz.

What maintenance or replacement will the ESTONE TJ-A210 need later?

The IR remote control uses a replaceable coin-cell battery that will need swapping when range drops; the switch itself has no moving parts or filters, so no other routine maintenance is required.

What limit appears first during sustained 8K 60 Hz use on the ESTONE TJ-A210?

The 48 Gbps HDMI 2.1 bandwidth ceiling is the first hard limit; if the source tries to push uncompressed 8K 60 Hz 4:4:4 HDR beyond that rate the switch will drop to a lower colour sampling or resolution.
