Q: What is DisplayLink® technology and is a driver required? Chevron Icon

A: DisplayLink® technology is a codec (sent over a USB 3.0 Type-A connection) that offers clear text and graphics. Since the docking station uses DisplayLink technology, you will need to install* the DisplayLink® Driver before using it.

*All Chromebooks using ChromeOS build R51 or later will work with DisplayLink® docks and adapters without additional driver installation. Windows 10S products using DisplayLink® technology will get their device drivers either from OEM pre-installation or from Windows Update.

Q: Do I need to update my laptop to the latest DisplayLink driver? How do I download the driver? Chevron Icon

Q: What if my device has a USB-C® port but it doesn’t support DisplayPort™ Alt Mode? Chevron Icon

A: If your USB-C® laptop doesn't support DisplayPort™ Alt Mode you will still receive video support since the SD4781P leverages DisplayLink® technology. If your USB-C® host device supports Power Delivery, then you can get up to 100W Power Delivery.
