When choosing a docking station for your laptop, it’s important to understand the differences between the technologies used for video transmission via the USB-C port. This can greatly impact your setup and user experience. This article will explain the differences between DisplayLink and DP Alt Mode (DisplayPort Alternate Mode) and how these technologies affect the use of docking stations.
DisplayLink: Universal compatibility with additional drivers
Docking stations using DisplayLink technology function as external graphics cards. This requires the installation of DisplayLink drivers but provides a high degree of compatibility with a wide range of devices.

Advantages of DisplayLink:
- Can be used with both USB-C and USB-A ports, as long as the port supports USB data.
- Universal compatibility with many different devices and operating systems.
- Convenient for older devices or devices without DP Alt Mode support.
DP Alt Mode: Video without drivers
Docking stations that support DP Alt Mode can transfer video directly from your device to the display without the need for external drivers. This means they can utilize your device’s built-in graphics processor, providing a seamless and driver-free experience.
Advantages of DP Alt Mode:
- No need for external drivers.
- Lower latency and higher performance, as it uses the internal graphics processor.
- Support for higher resolutions and multiple displays, depending on the device specifications.
How to identify your USB-C port
To determine if your USB-C port supports DP Alt Mode, you can refer to the specification manual for your laptop or contact the manufacturer. The image below shows different markings that can help you identify which technology your port supports.
Choosing the right docking station
When choosing a docking station, it’s important to consider which technology your device supports. DP Alt Mode provides a driver-free experience and high performance but relies on support from the device’s USB-C port. DisplayLink docking stations offer universal compatibility and can be used with a broader range of devices but require driver installation.
For those who have purchased a DisplayLink docking station, all you need is a port that supports USB data, meaning it can be used with both USB-C and USB-A. This makes DisplayLink docking stations a flexible and future-proof solution for many users.
