Product ID: TB32HD2
This high-performance Thunderbolt™ 3 adapter lets you add two 4K HDMI monitors to a computer through a single Thunderbolt 3 port (USB-C™). The Thunderbolt video adapter is compatible with computer systems that support Thunderbolt 3, such as models of Dell™ Precision and Dell XPS.
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.
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.
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.

Live Chat (opens in new window)When you troubleshoot issues with a video adapter, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue:
Video cables
Video adapter
Video source (such as a DVD player or computer)
Video destination (such as a monitor or projector)
To test your setup components, try the following:
Use the cable, video adapter, video source, and video destination in another setup to see if the problem is with the components or the setup.
Use a different cable, video adapter, video source, and video destination in your setup to see if the problem persists. Ideally, you should test a component that you know works in another setup.
When you test your cables, it is recommended that you do the following:
Test each cable individually.
Use short cables when you are testing.
When you test the video source and video destination, it is recommended that you do the following:
Remove the video adapter from your setup and test to make sure that the video source and video destination work together without the video adapter.
Test to make sure that the video source and video destination work together at the resolution that you want to use.
Note: In order for your setup to work properly, the video source, adapter, and destination all need to support the resolution that you are using.
Try the following:
The error “Out of Range” normally means that the resolution being output by the computer is not compatible with the display. Try lowering the resolution to see if that helps resolve the issue. You may need to connect another monitor or restart the computer or source to accomplish this.
If your computer is not detecting your Thunderbolt™ 3 device, try the following:
For more information about how to update the software, firmware, drivers, and BIOS or UEFI, refer to the website of the manufacturer of the Thunderbolt 3 host device. The following website includes links to some of the manufacturers of Thunderbolt 3 host devices: https://thunderbolttechnology.net/updates. If the manufacturer of your host device is not listed, you should contact the manufacturer or refer to their website for more information.
For more information about how to check which version of the Thunderbolt software and firmware you are currently using, see the following FAQ: https://www.startech.com/faq/thunderbolt-3-check-software-firmware.
For more information about Thunderbolt 3 host system and motherboard compatibility, refer to the Thunderbolt 3 Compatibility and Troubleshooting guide.
If you are only getting a single display to work with your Thunderbolt™3 device, make sure that your Thunderbolt 3 host device can support two separate DisplayPort lines over Thunderbolt 3.
While Thunderbolt 3 supports dual monitors over a single connection, not all Thunderbolt 3 host devices are designed to meet this requirement. If your Thunderbolt 3 host device does not meet this requirement, you cannot troubleshoot this issue with software, firmware, or driver updates, and you cannot use this device to achieve dual displays over Thunderbolt 3. If you are not sure whether your Thunderbolt 3 host device supports dual monitors, contact your Thunderbolt 3 host device manufacturer.
If you confirmed that your Thunderbolt 3 host device does support dual monitors and you are only seeing a single display, see the following FAQ: https://www.startech.com/faq/thunderbolt-3-update-software-firmware.
For more information about Thunderbolt 3 host system and motherboard compatibility, refer to the Thunderbolt 3 Compatibility and Troubleshooting guide.
If you receive an error message that your Thunderbolt device is not certified for PC use, try the following to resolve the issue:
To check which version of the Thunderbolt™ software, NVM firmware, and drivers you are running, do the following:
Review the versions of the software package, NVM firmware, PD firmware, and drivers. If you are not running the latest versions, navigate to the manufacturer’s website and download the latest versions.
When you connect a Thunderbolt™ device to any Windows operating system that can support Thunderbolt 3, a pop-up message appears. To use your device, complete the following:
If you accidentally set your Thunderbolt device to Do Not Connect in step three above, refer to the following FAQ: https://www.startech.com/faq/thunderbolt-3-denied-authentication.

You can use the Thunderbolt™ software to manage your Thunderbolt 3 devices on a computer running a version of Windows. To manage your Thunderbolt 3 devices, complete the following:
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 essential 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. USB-C devices do not include this symbol. For more information about USB-C, see the following FAQ: http://www.startech.com/faq/usb-c-port-capabilites

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.
