From this page you can download a reference driver for supported DisplayLink® USB graphics network device that is incorporated in your dock, adapter or monitor. However, please note that your original equipment manufacturer (OEM) provides drivers for your specific monitor, dock or adapter on their website, etc. DisplayLink recommends that you check with your OEM about recommended driver updates for your DisplayLink product. An OEM may not provide technical support for issues that arise from the use of DisplayLink's latest driver.
This driver includes support for the USB video and audio and Ethernet drivers for the DL-3xxx/DL-5xxx family of devices. Drivers for additional devices on your dock, adapter or monitor (such as third party Ethernet, audio, touch screen or wireless USB drivers) must be downloaded separately from the OEM's website.
