Overview

Multitask at the highest resolution

Thunderbolt 3 enables you to use a single port on your laptop to output dual 4K resolution to two independent displays. This performance enables you to run the most resource-demanding applications imaginable on two independent displays. You can output independent content to each display at resolutions of up to 4096 x 2160p @ 30Hz, which is great for editing 4K video or performing other Ultra HD tasks such as creating CAD drawings or reviewing medical imagery.

Supports dual 4K displays to work more efficiently

Functioning as an external 2-port graphics adapter with audio support, this is a compact and convenient alternative to a laptop dock, when you don’t need full docking capability.

With two UHD 4K displays, you can work more efficiently from laptop computers such as your Dell Precision, so you can accomplish more in the same amount of time. Plus, with each display delivering 4K performance, you can have four times the screen space compared to 1080p. Creative professionals can be more productive with the freedom to edit 4K video on one display, while previewing raw video playback on the second 4K display.

Won't drain system resources

This adapter helps to keep your system running at peak performance. Unlike USB external video solutions, Thunderbolt 3 lets you run Ultra HD 4K resolution at 30Hz on both displays without draining system resources.

Because it’s backward compatible with your high-definition 1080p displays, this is a great accessory for home, office or other desktop workspace applications.

The TB32HD2 is backed by a 2-year StarTech.com warranty and free lifetime technical support.

Frequently Asked Questions

Before You Buy

Components

Thunderbolt™ 3 is the latest version of the Thunderbolt standard for connecting computers and electronic devices. It is capable of the following:

  • Total bandwidth up to 40Gbps. Data transfer speeds are dependent on the other features that you are using in your setup.
  • USB 3.1 Gen 2 support.
  • 4K 60Hz video on one or two separate displays.
  • 5K 60Hz video on a single display.
  • A 10 GbE network connection between two Thunderbolt 3 compatible computers.
  • Up to six devices daisy-chained from a single Thunderbolt 3 port.
  • Alternate modes, such as DisplayPort Alternate Mode (DP Alt Mode).
  • Bi-directional power delivery up to 100W (not all Thunderbolt 3 devices support power delivery).

USB-C and Thunderbolt 3

Thunderbolt 3 uses the USB-C connector, but not all host connections, cables, and devices with a USB-C connector support Thunderbolt 3. This means that a USB-C device is compatible with a Thunderbolt 3 host connection, but a Thunderbolt 3 device is not compatible with a USB-C host connection. Therefore, it is important to know whether you have a USB-C or a Thunderbolt 3 host, cable, or device.

To determine if your component is a Thunderbolt 3 device, look for the Thunderbolt 3 symbol (shown below). USB-C devices do not include this symbol.  For more information about USB-C, see the following FAQ: https://www.startech.com/faq/usb-c-port-capabilites.

Backwards compatibility

If you use an adapter, Thunderbolt 3 host connections are compatible with Thunderbolt 1 and Thunderbolt 2 devices. You can use the StarTech.com TBT3TBTADAP to make a Thunderbolt 3 host connections backwards compatible.

Thunderbolt 3 devices are not backwards compatible with Thunderbolt 1 and Thunderbolt 2 host connections.

No, you cannot use this device to increase the maximum number of displays that a video card supports. For example, if your video card only supports up to three displays and you add this device to your setup, your display limit is still three displays.

If you have connected more than one of this device to the same computer and are experiencing display issues, you should make sure that your video card can support the number of displays that you are using in your setup.

This device requires that the Thunderbolt 3 host system provides 15W of bus power to the Thunderbolt 3 port. Thunderbolt 3 host systems that do not provide the full 15W of bus power will not work with this device.  

Refer to the information provided by the manufacturer to confirm the power delivery capabilities of your host system.
