# Why am I unable to use my external displays with the VT100?

The **VisionTek VT100** uses DisplayLink technology to connect your computer to external displays. **DisplayLink software must be installed** for the external displays to function properly.

[Download DisplayLink Software](https://www.synaptics.com/products/displaylink-graphics/downloads?utm_source=chatgpt.com)

**Important**

- Install the latest DisplayLink software for your computer's operating system.
- Make sure the VT100 is securely connected to your computer.
- Make sure your external displays are powered on and connected securely.
- Your computer and operating system must meet the requirements for the VT100.

If your external displays are still not working after installing DisplayLink software, disconnect and reconnect the VT100 and check your computer's display settings.
