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.

For more information about Power Delivery, refer to the manufacturer of your hardware.

If you set your display to 4K@60Hz and connect a display to the DisplayPort output on the laptop docking station, your display may flicker. This issue only affects certain monitors and is a result of an interoperability issue between the hardware used in the display and the docking station. This issue is not specific to StarTech.com docking stations.

To resolve this issue, try any of the following:

  • Connect a USB-C to DisplayPort cable from the USB-C Thunderbolt 3 port on the docking station to the DisplayPort input on the display. (StarTech.com product ID for the USB-C to DisplayPort cable: CDP2DPMM1MB.)
  • Connect a USB-C to HDMI 2.0 cable from the USB-C Thunderbolt 3 port on the docking station to the HDMI input on the display. (StarTech.com product ID for the USB-C to HDMI 2.0 cable: CDP2HD4K60.)
  • If you are using a dual monitor setup, connect a dual DisplayPort adapter from the USB-C Thunderbolt 3 port on the docking station to the DisplayPort input on the displays. (StarTech.com product ID for the Thunderbolt 3 dual DisplayPort adapter: TB32DP2.)
  • Disable MST (Multi Stream Transport) or DisplayPort 1.2 mode on your display and enable 4K@30Hz. Refer to the information provided by the manufacturer for assistance. 

This docking station provides 15 watts of power, which may be enough to display a charging icon, but is likely not enough to restore battery power while the system is on and being used. If an icon is displayed and the system is put into sleep mode, battery power will be restored slowly.

If your computer is not detecting your Thunderbolt™ 3 device, try the following:

  • Update the Thunderbolt software on your Thunderbolt 3 host device.
