How to use

Insert the USB‑C connector of the adapter into the USB‑C port of your laptop, tablet or phone. Connect an HDMI cable from the adapter’s HDMI output to an external monitor or projector, and plug USB‑A peripherals into the USB‑A port. On most systems the external display will be detected automatically; use your operating system display settings to select mirror, extend or primary display mode. If a device requires USB host mode or alternate display mode, ensure that the source device supports those functions.

Recommendations

For stable video output at 4K 30Hz, use a high‑quality HDMI cable and connect to a display that supports the specified resolution and refresh rate. Avoid forcing the adapter into tightly packed ports and disconnect gently to prolong connector life. If the host device does not detect the display, check USB‑C alternate mode support and update the device firmware or drivers where applicable.
