4-in-1-out HDMI 2.1 switch for gaming
The ESTONE TJ-A140 routes four HDMI 2.1 sources to a single display. It handles 8K at 60 Hz and 4K at 120 Hz with 48 Gbps bandwidth. The unit supports HDCP 2.2 and compressed audio formats including Dolby Atmos and DTS-HD. A compact black enclosure measures 12 by 6 by 0.08 inches and weighs 1.2 ounces.
Passive switching with remote control
No active cooling is required because the switch draws minimal power through its DC 5 V 1 A input. Operation is silent with no fans or moving parts. An IR remote selects inputs instantly, while front-panel LEDs show the active port and power status. Automatic switching jumps to a newly connected source without user intervention.
Stable signal under continuous 8K 60 Hz use
The 48 Gbps bandwidth sustains full 8K 60 Hz 4:4:4 HDR streams without compression artefacts during extended sessions. HDCP 2.2 handshakes remain reliable across source changes, preventing signal drops. The switch maintains link integrity for 4K 120 Hz gaming signals over long periods. It does not support setups that require more than four inputs or dual simultaneous outputs.

Questions about this item
How do I install the ESTONE TJ-A140 4-in-1-out HDMI 2.1 switch, and which step do people often miss?
Connect up to four source devices to the four HDMI 2.1 input ports, connect the display to the single HDMI 2.1 output, plug the included DC 5V/1A power adapter into the power port, then use the remote or front button to select the active input; the step most people miss is powering the unit before expecting signal switching.
What maintenance or replacement will the ESTONE TJ-A140 HDMI 2.1 switch need over time?
No scheduled maintenance is required; if the DC 5V/1A power adapter fails or the remote battery runs out, replace only that accessory — the switch itself has no user-serviceable parts.
What limit appears first during sustained 8K@60Hz or 4K@120Hz use on the ESTONE TJ-A140?
The 48 Gbps bandwidth ceiling and HDCP 2.2 handshake stability are the first limits; cable lengths beyond the HDMI 2.1 passive spec or marginal source compliance will cause drop-outs before the switch overheats.
