The UGREEN USB-C Multifunction Adapter 15531 HDMI USB 3.0 Ethernet is a compact hub that expands a USB-C port into an HDMI output, multiple USB 3.0 ports and a wired Ethernet connection. Designed for laptops, tablets and other USB-C devices, the adapter enables external display connection, fast USB data transfer and stable wired network access in a single portable unit. Its small footprint makes it suitable for mobile work, meetings and home office setups.

Advantages

This multifunction adapter combines HDMI video output, high-speed USB 3.0 ports and a Gigabit-capable Ethernet interface in one device, reducing the need for several separate dongles. The USB 3.0 ports support faster data transfer rates compared to USB 2.0, while the HDMI output allows connection to external monitors, projectors or TVs for presentations and expanded desktop use. The wired Ethernet port provides a reliable network connection when Wi‑Fi is weak or unavailable. The adapter’s compact design supports easy transport and quick setup without tools.

How to use

Plug the adapter’s USB-C connector into the USB-C port of your laptop, tablet or compatible device. Connect an HDMI cable from the adapter’s HDMI output to an external monitor, TV or projector to extend or mirror the display; adjust display settings on the host device as needed. Insert USB devices into the USB 3.0 ports for data transfer or to connect peripherals such as keyboards, mice or external drives. For wired internet access, connect an Ethernet cable to the adapter’s network port. No additional drivers are typically required for modern operating systems; follow on-screen prompts if the host device requests permission to access connected devices.

Recommendations

Use a high-quality HDMI cable for reliable video output and a Category 5e or higher Ethernet cable for optimal network performance. Avoid placing heavy objects on the adapter or bending the connector sharply. When connecting multiple high-power peripherals, ensure the host device provides sufficient USB-C power or use powered hubs for power-hungry accessories.
