This high-performance Thunderbolt™ 3 adapter lets you add two 4K 60Hz DisplayPort monitors to your Windows® or Mac computer through a single Thunderbolt 3 port, or it can be used to connect your Thunderbolt 3 port to a 5K 60Hz display using two DP cables.

The Thunderbolt video adapter is compatible with computer systems that support Thunderbolt 3, such as models of MacBook Pro, Dell™ Precision, and Dell XPS. Thunderbolt 3 is a protocol that uses the USB-C™ connector, but your computer system must support Thunderbolt 3 in order for the adapter to function as expected. If you connect the adapter to a USB-C port that does not support Thunderbolt 3, the adapter will not function.

Connect two UHD 4K displays to your computer at 60Hz resolution

The Thunderbolt 3 to DisplayPort adapter connected to two 4K monitors.

With an unprecedented 40Gbps of throughput, Thunderbolt 3 enables you to achieve the previously impossible feat of using a single port on your laptop to output dual 4K resolution at 60Hz 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 (60Hz), which is perfect for editing 4K video or performing other Ultra HD tasks such as creating CAD drawings or reviewing medical imagery.

Connect a 5K display to your computer at 60Hz resolution

The Thunderbolt 3 to DisplayPort adapter connected to a single 5K monitor.

For added versatility, the Thunderbolt 3 adapter can be used to connect two DisplayPort channels to a single 5K display. Using a Thunderbolt 3 adapter is the only way to connect a 5K display to computers that don’t have multiple DP or Thunderbolt 3 ports, such as your Dell Precision 15 3000 Series workstation.

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 your laptop, 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 60Hz 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 TB32DP2T is backed by a 2-year warranty and free lifetime technical support.

(5 stars) Works great with me Dell XPS15

I previously purchased a Dell Thunderbolt for my Dell XPS 15 laptop. It was noisy, then it stopped working after 2 months. Then I switched to StarTech's version of Thunderbolt technology. It works great! Super Quiet! Wish it had more PCI ports for monitors and more USB ports.

(5 stars) Works well with late 2016 MacBookPro Retina

I mistakenly thought all USB-C to Displayport adapters were the same. I found that the one I had did not work with my Mac. I searched the Web and found this one that specifically states it is for either Mac and Windows machines. I plugged my two Displayport cables into it and to my two 4K monitors - the USB-C end into one of the four ports on the Mac. It took a few seconds to find everything and then both monitors were recognized at full resolution :-) Great product - thanks

(4 stars) Excellent

Nice, solid, metal case. The cable is long enough to move it out of the way. Easy to install.

(5 stars) Triple Display

This product enabled me to get a triple display going with my usb-c laptop (two monitors and the laptop screen). It was plug n play easy to setup and the image quality is flawless. If you have a modern laptop that doesn’t have any ports other than usb-c/TB3 and you don’t want to drop $400 for a docking station to be able to get more monitors hooked up then this is the perfect product for you. I’ll definitely be using this daily.
