How to install SIIG USB-C to 4-in-1 Multiport Video Adapter

• Connect the host: Plug the USB-C end of the adapter into a Thunderbolt 3 or DP Alt Mode-enabled USB-C port on your computer. Ensure the port supports video output to maximize compatibility.
• Attach displays: Connect each display to the corresponding output on the adapter using the appropriate cables (DVI, VGA, DisplayPort, HDMI). If you’re using multiple displays, verify cables are firmly seated and the correct input sources are selected on each monitor.
• Configure display settings: Open your operating system’s display preferences and arrange the displays (mirror, extend, or custom layout). Depending on your OS version, you may drag and extend the desktop across screens and set preferred resolutions for each display.
• Power considerations: If your host provides sufficient power through USB-C, no external power is required. If you notice dim displays or limited functionality, check your system’s power settings or consider connecting to a powered USB-C port or a powered hub if needed.
• Driver and firmware notes: In most cases, the adapter works without additional drivers. If you encounter any issues, ensure your operating system is up to date and check for any firmware or display driver updates on the host device.
