With dual-monitor support, the dock makes it easy to connect two 4K Ultra HD displays (one DisplayPort and one Thunderbolt 3 USB-C™ port), or a single Thunderbolt 3 display (60Hz). For a dual DisplayPort monitor solution right out of the box, a USB-C to DisplayPort cable (with an extended length of 6 ft./1.8 m) is included, for connecting a second DisplayPort monitor to the Thunderbolt 3 port.

Plenty of power, with support for USB Power Delivery

This Thunderbolt 3 docking station comes with a 170W power adapter for powering and charging (up to 85W) your Windows laptop or MacBook Pro, while simultaneously powering all of the peripheral devices that are connected to the dock. This eliminates the need to use two separate power adapters for your laptop and the docking station, which minimizes the clutter around your workstation.

Finish your work faster with Thunderbolt 3

Thunderbolt 3 is the fastest connection available, and it supports multiple video channels, data, and power without impacting system performance. With up to 40Gbps of throughput, you can add extra displays to your laptop, access files faster, and reduce waiting, so you can accomplish more in the same amount of time.

Multitask at the highest resolution

If you need a larger, higher-resolution viewing area, this dock can help. You can connect two 4K Ultra HD displays, so it’s perfect for working with high-bandwidth or graphics-intensive content. 

The Thunderbolt 3 dock supports two 4K (3840 x 2160p or 4096 x 2160p) monitors through the DisplayPort and Thunderbolt 3 USB-C port (a USB-C video adapter might be required depending on monitor). For dual monitors, simply connect your first DP monitor through the dock’s DisplayPort, and a second monitor through the dock’s extra Thunderbolt 3 port using the included USB-C to DisplayPort Adapter Cable or to a USB-C based monitor. The Thunderbolt dock will also work with legacy displays, such as VGA monitors, when coupled with a USB-C to VGA adapter or DP to VGA adapter.

With support for two 4K monitors, the Thunderbolt dock makes it easier to multitask when you’re working with high-definition video or other complex work. Single 5K resolution is supported on 5K capable Thunderbolt 3 monitors through the Thunderbolt 3 USB-C port only.

Connect all of your peripherals using only a single cable

Using the single included Thunderbolt 3 cable and a single port on your laptop, you can transform your macOS Sierra (or later) or Windows® 7 (or later) laptop into a full-size workstation with access to new and legacy technologies through a number of different port types. The dock is ideal for virtually all Thunderbolt 3 equipped laptops such as the Dell™ XPS 13, Dell XPS 15, and the Apple MacBook Pro 13 and 15.

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.

Thunderbolt symbol: https://sgcdn.startech.com/005329/media/products/gallery_large/TBLT3MMXM.B.jpg.

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.

Thunderbolt™ 3 is capable of 100W of bi-directional power; however not all manufacturers will implement power delivery, or implement power delivery at the full 100W.

Optical Thunderbolt 3 cables do not support power delivery at any wattage.

Refer to the information provided by the manufacturer to confirm the power delivery capabilities of the following components:

  • The Thunderbolt 3 host connection
  • The Thunderbolt 3 cable
  • The Thunderbolt 3 device (for example, a hard drive docking station)

Although the Thunderbolt™ 3 standard is capable of data transfer speeds up to 40Gbps, not every cable can support this bandwidth. For example, cables over a certain length or made with certain materials are only capable of data transfer speeds up to 20Gbps. 

To confirm the capability of your Thunderbolt 3 cable, refer to the information provided by the manufacturer. StarTech.com lists the capabilities of the Thunderbolt 3 cables on the individual product pages.

There are two different Thunderbolt 3 cable symbols: the 20Gbps symbol and the 40Gbps symbol. The 20Gbps symbol is composed of the Thunderbolt 3 symbol, and the 40Gbps symbol is composed of the Thunderbolt 3 symbol and the number three. These images are shown below.

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: http://www.startech.com/faq/usb-c-port-capabilites.
