Three-input HDMI 2.1 switch

The ESTONE TJ-A113 connects three HDMI 2.1 sources to a single display. It is built for users who need to toggle between consoles, streaming sticks or a PC without unplugging cables. An IR remote and a front-panel button both select the active input. LED indicators show which port is live. The unit requires no drivers and draws power from the connected devices.

Bandwidth and resolution limits

The switch passes signals up to 48 Gbps, enabling 8K at 60 Hz, 4K at 120 Hz and 1080p at 240 Hz. Dynamic HDR, VRR and chroma subsampling 4:2:0, 4:2:2 and 4:4:4 are supported. All three inputs and the output share the same HDMI 2.1 female connectors. Performance at the highest modes depends on using certified Ultra High Speed HDMI cables. The device does not offer automatic switching.

Three-to-one port configuration

This model provides exactly three HDMI 2.1 inputs and one HDMI 2.1 output. Buyers who need to connect more than three sources or who require multiple simultaneous outputs should choose a different switch. The aluminium enclosure measures 8 by 5 by 0.03 inches and weighs 0.634 ounces.

Questions about this item

Should I pick the TJ-A113 over a 2-port or 4-port HDMI 2.1 switch?

Choose the TJ-A113 when you have exactly three HDMI 2.1 sources — such as a PS5, Xbox Series X and a streaming stick — that must share one 8K display; fewer ports leave a device unplugged, more ports add cost you will not use.

Does the 48 Gbps bandwidth mean I can run 8K at 60 Hz and 4K at 120 Hz simultaneously?

The 48 Gbps link carries one active signal at a time; you can switch between an 8K 60 Hz source and a 4K 120 Hz source instantly, but only the selected input is transmitted to the display.

What does the HDMI 2.1 interface cap in practice with this switch?

HDMI 2.1 on the TJ-A113 caps at 48 Gbps, enabling 8K at 60 Hz, 4K at 120 Hz, 1080p at 240 Hz, Dynamic HDR, VRR and 4:4:4 chroma — all limited by the single active 3-in-1-out path.
