What the ESTONE TJ-A140 does and who needs it

The ESTONE TJ-A140 is a 4-input, 1-output HDMI 2.1 switch that lets you route up to four source devices to a single display. It suits gamers and home-theatre users who want to connect multiple 8K- or 4K-capable consoles, streamers or PCs without swapping cables. Buyers who need simultaneous picture-in-picture or matrix routing to several screens should look elsewhere.

Bandwidth and resolution ceiling

The switch passes 48 Gbps and supports 8K at 60 Hz or 4K at 120 Hz with HDCP 2.2, so the single figure that decides fit is whether your sources and display require that full 48 Gbps path. Lower-bandwidth 18 Gbps devices will also work, but the headroom exists for uncompressed 8K 4:4:4 HDR signals.

Behaviour during extended sessions

Powered by an included DC 5 V 1 A adapter, the unit maintains a stable 48 Gbps link without thermal throttling during long gaming or playback sessions. Automatic source detection and IR remote switching keep the active port consistent, and LED indicators confirm the selected input at a glance.

Questions about this item

What does 8K at 60 Hz and 4K at 120 Hz mean for my gaming setup?

The switch passes 8K resolution at 60 Hz and 4K at 120 Hz, so a compatible console or PC can output those modes through the switch without downscaling.

How does the HDMI 2.1b and 48 Gbps bandwidth limit what I can connect?

HDMI 2.1b with 48 Gbps bandwidth supports full 8K 60 Hz, 4K 120 Hz, HDR and 4:4:4 chroma, but any source or cable limited to HDMI 2.0 will fall back to 18 Gbps and lower refresh rates.

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

It measures 12 by 6 by 0.08 inches, weighs 1.2 ounces and requires a DC 5 V 1 A power adapter, so it fits in a shallow shelf and needs a nearby USB or mains outlet.
