48 Gbps bidirectional HDMI 2.1 switch

This Jansicotek unit works as a 1x2 switch or a 2x1 splitter at up to 48 Gbps bandwidth. It passes 8K at 60 Hz, 4K at 120 Hz and 1080p at 240 Hz to a single active display. A front-panel button selects the active source or display.

Gamers and multi-console owners needing one screen

The device suits setups where only one monitor or TV is used at a time. It does not drive two screens simultaneously, so buyers who want mirrored or extended desktop output should look elsewhere. No external power supply is included in the box.

Manual source or display selection via front button

Switching between the two connected HDMI ports requires a physical press of the Select key each time. There is no automatic sensing or remote control, so the button must be reachable in the intended installation.

Questions about this item

Will the mechanical selector button or the HDMI ports wear out from daily switching?

The unit uses a physical Select button and two HDMI female ports rated for repeated insertion cycles; no moving parts other than the button itself.

What is the maximum bandwidth the switch can sustain without signal degradation?

The adapter is specified for 48 Gbps throughput, matching the HDMI 2.1 ceiling for 8K at 60 Hz or 4K at 120 Hz.

Does the device need active cooling or external power when running continuously?

It draws power from the included USB-A-to-Micro-B cable and has no fan; heat output is low enough for passive operation.
