How to use

Connect each HDMI source to the switch’s HDMI input ports and connect the switch’s HDMI output to the display. Plug the supplied 5V, 1A power adapter into the switch and a mains outlet. Power on the display and source devices; use the switch controls (button or selector) to choose the active input. Verify that the display is set to the correct HDMI input and that source devices are configured to output compatible resolutions. When changing sources, allow a few seconds for the display and source device to negotiate the video signal.

Recommendations

For reliable 4K performance, use high-quality HDMI cables rated for the target resolution and avoid excessively long cable runs. If a device does not display correctly after switching, power-cycle the source and the display, then reselect the input. Keep the switch in a well-ventilated location and ensure the 5V/1A adapter is used as specified to avoid power-related instability.
