HP PCs - Connecting Thunderbolt Devices

This document applies to HP and Compaq PCs with a Thunderbolt port.
About Thunderbolt
Thunderbolt is a high-speed Input/Output (I/O) technology that enables the computer to connect to up to six devices through a single connector. Data and display signals can be carried over one Thunderbolt cable at the same time.
To use a Thunderbolt device with your HP or Compaq computer, you must have the following:
  • A computer with a Thunderbolt port. The Thunderbolt port is compatible with Mini DisplayPort, enabling you to connect to native DisplayPort devices.
  • A Thunderbolt device.
      note:
    HP recommends using Thunderbolt devices that are certified to work with Windows. For more information, see the next section, About Thunderbolt compatibility
About Thunderbolt compatibility
Thunderbolt devices can be certified to work with the Windows operating system, Mac OS, or both Windows and Mac OS. By default, HP and Compaq computers are configured to recognize only Thunderbolt devices that are certified to work with Windows. For a list of Thunderbolt devices and their operating system certifications, go to https://thunderbolttechnology.net/products.
  note:
Check the device manufacturer's Web site for any known issues and for a Windows driver before connecting a Thunderbolt device to the computer. Some devices listed as certified for Windows may still require you to configure the firmware or download and install a Windows driver before they are recognized by your computer. This situation can happen when a device was recently certified for Windows, after your device was manufactured. Operating system compatibility cannot be updated on Thunderbolt devices after they are manufactured.
To configure the Thunderbolt firmware on the computer and use a non-Windows certified device with an HP Spectre XT TouchSmart 15-40xx or 15-41xx Ultrabook, see Configuring the Thunderbolt firmware on an HP Spectre XT TouchSmart 15-40xx or 15-41xx Ultrabook.
  note:
A device that is not certified for Windows may not be recognized by the computer, even after configuring the firmware. Using a non-Windows certified Thunderbolt device can cause performance issues, including intermittent drops in connectivity and data loss. Check the device manufacturer's Web site for any known issues and install a Windows driver if one is available.
