1. Our driver may not be installed or is out of date.  Install the latest driver from StarTech.com’s website.
2. The primary display adapter for the computer has an outdated or basic driver installed. Update the video driver using the manufacturer’s support site.
3. The product requires an existing video controller (onboard or discrete) from Intel, AMD, or NVIDIA.  The video controller must have a WDDM (Windows Display Driver Model), compatible driver. Most video controllers from 2008 or newer will meet this requirement.
4. An incompatible operating system is being used (i.e., MCT based adapter and macOS).  If using a Mac, we recommend exchanging the product for a DisplayLink based version.
5. The display connected to the StarTech.com adapter is set to the wrong video input. Use the display’s on-screen display menu to select the correct input.
6. The following only applies to computers running Windows 8.1 or older operating systems. USB video adapters and some USB docking stations use different chipsets (ex. DisplayLink/Synaptics, MCT, Fresco, Silicon Motion). They will not work together on the same computer. If you are running into problems trying to use multiple USB video products, please check our Tech Specs to determine which chipset each product uses. If they do not match, then they will not work together.

Your user account may require administrator privileges to install the driver.  If the computer is managed by the IT department or service provider, they may need to be contacted to help with this step.

Disable hardware acceleration in each browser and Office application, then close and re-open each application.

Ensure the Sound Playback device in Windows (or Output device in macOS) has been set to be our USB audio device.

If the display connected through your USB display adapter does not wake up after your computer has been in extended hibernation, it is likely that Windows has automatically turned off the USB Root hub to save power.

Touchscreen Monitors

A mixture of touchscreen and non-touchscreen displays can cause a conflict with your internal video card. Because of this limitation, touchscreen functions may be disabled when the USB Video Adapter is connected, or the USB Video Adapter may not work at all. Contact the manufacturer of your system to confirm whether your specific model can support a secondary display or not.

All-in-One Computers

Many all-in-one computer systems limit the number of possible monitors to one. This is a limitation in how all-in-one computers are typically manufactured, so adding an external display may not be possible regardless of which USB video adapter is used. Contact the manufacturer of your system to confirm whether your specific model can support a secondary display or not.
