For an external display, attach an HDMI cable directly between the adapter and the monitor using an HDMI-to-HDMI connection; use an HDMI 2.0 cable for best results. Insert MicroSD or SD cards into their respective slots until you hear the click on the MicroSD slot to confirm proper seating. Plug an Ethernet cable into the RJ-45 port for wired network access. If you need to charge the host device while using the adapter, connect a USB-C power source to the pass-through charging port (maximum 60W).

Recommendations

Use high-quality HDMI 2.0 cables for optimal 4K performance and ensure direct HDMI-to-HDMI connections. When inserting the MicroSD card, wait for the audible click to confirm full insertion. To maintain stable operation, avoid exposing the adapter to temperatures outside the stated operating range.
