About Thunderbolt 3
Thunderbolt 3 technology uses the USB-C connector, with bandwidth up to 40Gbps.
It supports USB 3.1, DisplayPort 1.2, PCI Express 3.0, Thunderbolt 2, first-generation
Thunderbolt, and increased power delivery to connected devices.
Thunderbolt technology supports both video and data throughput. However, it
prioritizes video bandwidth to help ensure seamless display performance. The
performance of the remaining dock functions depends entirely on your display
configuration.
Thunderbolt 3 products must be used with Thunderbolt 3 cables.
About DP alt mode (DisplayPort alternative mode)
DP alt mode is a specification that allows a DisplayPort video signal to transfer over
USB-C. It enables the use of the USB-C interface for DisplayPort signals. Thunderbolt
3 supports the full USB-C standard, including support for DP alt mode. Because the
docking station supports DP alt mode, you can connect Thunderbolt 3 or USB-C based
video devices, cables, or adapters to the secondary Thunderbolt 3 port on the rear of
the docking station.
About USB power delivery 2.0
USB power delivery 2.0 is a specification that allows power (up to 100 watts) to be sent
over a USB-C or Thunderbolt 3 cable that supports the specification.
The TB3DK2DPWUE supports USB power delivery 2.0 profile 1, delivering up to 15
watts of power to each Thunderbolt 3 USB-C port.
Thunderbolt temperature
Due to the high-performance of Thunderbolt technology, Thunderbolt products
sometimes generate more heat than traditional hardware. Therefore, it’s normal for the
docking station to warm up when in use. Placing your laptop on the docking station’s
surface will result in even higher temperatures.
These higher temperatures do not represent a safety hazard to users or to hardware.
About USB 3.0 and USB 3.1 Gen 1
USB 3.0 is also known as USB 3.1 Gen 1. This connectivity standard offers speeds up
to 5Gbps. Any mention of USB 3.0 in this manual or on the StarTech.com website for
TB3DK2DPWUE refers to the 5Gbps USB 3.1 Gen 1 standard. Any mention of USB 3.1
Gen 2 refers to the 10Gbps Gen 2 standard.
