While the form factor of the typical notebook computer may be shrinking to netbook or Apple Air sizes, the need for more display screen real estate is increasing.

Who is it for?

The OWC USB 2.0 Display Adapter is designed for users who need to extend the video display of their computer beyond one screen but do not have an external video port available. The most likely user for this display technology is one with a netbook computer or other small/thin device. The devices history is closely tied to Apple Computer and the Apple Air, for example.

What problem does it solve?

For users carrying netbook PCs or other small devices, there is often a need to display what is on the screen beyond the confines of a built-in monitor. The OWC USB 2.0 Display Adapter provides that capability without requiring an external video port.


  • Installation: The software installation and configuration from the accompanying CD-ROM is quick and easy. Because the technology is based on the established Display Link applications, this device just works out of the box.
  • Multiple displays: The software can support up to six USB display adapters, so adding extra displays is not a problem.
  • Hot plug: Attaching and detaching monitors does not require that the system reboot to accommodate the change.

What’s wrong?

  • Niche: The OWC USB 2.0 Display Adapter works great, but if you have already have an external video port the device is redundant and not necessary. This means the adapter has very specific market.
  • Performance: While the performance for general activities like PowerPoint presentations is adequate, multimedia will bog down the adapter. Once again, you will want to use an external video port or the built in display for high pixel rate applications.
