Product FAQs

Before You Buy

There is no video signal shown on the display. How do I fix this?

  1. Our driver may not be installed or is out of date.  Install the latest driver from’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 The primary display adapter for the computer has an outdated or basic driver installed.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 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.
