What Is DisplayLink And Why Would I Need It?

DisplayLink is a technology that allows you to connect additional displays to your computer via USB (including USB-A, USB-C, and even Ethernet in some cases) rather than relying solely on your computer’s built-in video outputs like HDMI or DisplayPort. It works by using your computer’s CPU and GPU to process the video signal and then transmits it over the USB connection to the DisplayLink device, which then converts it to a standard video signal for your monitor.

The primary benefit is expanding your display setup beyond the limitations of your computer’s physical video ports. This is particularly useful for laptops with limited ports, adding more monitors to a workstation, or connecting displays in situations where traditional video cables are inconvenient or impractical. DisplayLink can be a cost-effective solution compared to upgrading your entire computer to gain more video outputs.

What Are The System Requirements For Using DisplayLink?

The system requirements for DisplayLink are fairly modest but crucial for optimal performance. You’ll need a computer running a supported operating system, typically Windows (various versions), macOS, ChromeOS, or Linux. Check the DisplayLink website for the latest supported versions, as these can change with updates. In addition, your computer needs sufficient processing power (CPU) and graphics capabilities (GPU) to handle the encoding and transmission of the video signal, especially for high-resolution displays.

Memory (RAM) is also a factor, as DisplayLink drivers consume system resources. Ideally, you should have at least 4GB of RAM, but 8GB or more is recommended for multiple high-resolution displays. Ensure you have the correct drivers installed for your operating system, which can be downloaded from the DisplayLink website or often provided by the manufacturer of the DisplayLink adapter or docking station.

How Do I Install DisplayLink Drivers?

The installation process for DisplayLink drivers generally involves downloading the appropriate driver package from the DisplayLink website for your operating system. Before installing, it’s recommended to disconnect the DisplayLink device from your computer to avoid any conflicts during installation. Run the downloaded installer and follow the on-screen instructions. On Windows, you may need to grant administrative privileges for the installation to proceed correctly.

Once the installation is complete, restart your computer. After restarting, connect the DisplayLink device to your computer. Your operating system should now recognize the device and use the installed drivers to enable the connected displays. You might need to configure display settings within your operating system to arrange the monitors and adjust resolutions as needed.

What Troubleshooting Steps Can I Take If DisplayLink Isn’t Working?

If DisplayLink isn’t working, start by ensuring the DisplayLink device is properly connected to your computer and powered on (if applicable).

Yes, DisplayLink can support audio, depending on the specific DisplayLink device and drivers you are using. Most DisplayLink adapters and docking stations include audio outputs, such as headphone jacks or speaker connections, and some may even support audio transmission through the USB connection directly to the connected monitor if it has built-in speakers.

The audio functionality is usually enabled through the DisplayLink drivers, which create virtual audio devices in your operating system. You can then select these virtual audio devices as your default audio output in your system settings. Note that the audio quality and performance may vary depending on the quality of the DisplayLink device and the USB connection.

Are There Any Limitations To Using DisplayLink?

One limitation of DisplayLink is the potential for increased CPU and GPU usage, as the technology offloads video processing to your computer’s resources. This can impact overall system performance, particularly on older or less powerful computers, especially when driving multiple high-resolution displays. Latency, as mentioned earlier, is another limitation, making it less suitable for applications requiring real-time responsiveness like gaming.

Another consideration is that DisplayLink relies on drivers, which can sometimes be problematic. Driver incompatibilities, updates, or conflicts with other software can cause issues. Furthermore, some applications or operating systems may not fully support DisplayLink, leading to compatibility problems. Finally, the image quality and color accuracy might not be as pristine as with direct video connections, although this is often imperceptible for everyday use.
