Three-port HDMI 2.1 switch

The ESTONE TJ-A125 is a unidirectional 3-in-1-out selector that connects three HDMI 2.1 sources to a single display. It is built for users who need to switch between consoles, streamers or players without swapping cables.

48 Gbps bandwidth and 8K60 support

The switch passes 48 Gbps throughput, enabling 8K at 60 Hz, 4K at 120 Hz and lower resolutions up to 1080p 240 Hz. This bandwidth figure is the single specification that determines whether the unit can handle your highest-resolution source.

Sustained 8K signal integrity

Aluminium housing and HDCP 2.2/2.3 compliance maintain stable 8K60 and 4K120 transmission during extended sessions. The device is not bi-directional, so it cannot distribute one source to multiple displays.

Questions about this item

What does the 48 Gbps bandwidth actually allow on a real display?

It carries 8K at 60 Hz, 4K at 120 Hz, 1440p at 165 Hz and 1080p at 240 Hz with Dynamic HDR and eARC audio.

Which HDMI version and HDCP level does the switch use, and what does that limit?

All four ports are HDMI 2.1 and support HDCP 2.2 and 2.3, so protected 8K and 4K 120 Hz streams pass through without downgrade.

How much space does the aluminium case need on a desk or shelf?

The unit measures 12 by 6 by 0.08 inches and weighs 1.2 ounces, so it fits in a tight gap behind a monitor or TV.
