How to use

Connect the docking station to your laptop using the USB Type-C cable and allow the host system to detect the device; most modern operating systems will install required drivers automatically or prompt for driver setup. Plug your monitor or projector into the VGA port and attach wired network cable to the RJ-45 connector for a stable internet connection. Use the USB-A ports for keyboards, mice, printers or external storage and connect headphones or speakers to the 3.5 mm jack. Verify display settings on your laptop to select the desired resolution and extended or mirrored display mode.

Recommendations

For reliable video output at higher resolutions, ensure your laptop’s USB-C port supports video output (DisplayPort Alt Mode) and set the display resolution in the operating system. To maximize network performance, use a Cat5e or higher Ethernet cable. Keep drivers up to date for best compatibility with connected peripherals.
