Frequently Asked Questions - TB3DK2DPWUE StarTech.com
What does the TB3DK2DPWUE adapter do?
The StarTech.com TB3DK2DPWUE is a Thunderbolt 3 adapter that lets you connect up to two DisplayPort monitors to your computer through a single Thunderbolt 3 port. It's ideal for expanding your workspace with high-resolution displays.
Does this adapter support dual 4K monitors?
Yes, it supports dual 4K displays at up to 4096 x 2160 @ 60 Hz each. This makes it perfect for video editing, design, or financial applications where ample screen real estate matters.
Is this adapter compatible with my MacBook Pro?
The adapter works with Thunderbolt 3 equipped MacBook Pro, MacBook Air, iMac, and Mac mini models. Note that it requires a Thunderbolt 3 port; a standard USB-C port with no Thunderbolt support will not work.
Does it require an external power supply?
No. The adapter is bus-powered, drawing its power directly from the Thunderbolt 3 port. You simply plug it in and connect your monitors — no external power adapter needed.
Can I use this adapter with a USB-C port that is not Thunderbolt 3?
No. The TB3DK2DPWUE specifically uses Thunderbolt 3 technology. If you connect it to a non-Thunderbolt USB-C port, it will not provide video output. Check that your device has a Thunderbolt 3 port (often marked with a lightning bolt icon).
How do I connect the adapter?
Connect the integrated Thunderbolt 3 cable to your computer, then plug your DisplayPort cables into the two DisplayPort outputs on the adapter. Your displays should be detected automatically. If not, update your GPU drivers or restart your computer.
Does it support audio over DisplayPort?
Yes, the DisplayPort interface supports audio transmission. You can enable audio output to the monitor in your operating system's sound settings if your monitor has speakers and supports audio over DisplayPort.
What operating systems are supported?
The adapter is compatible with macOS 10.12 or later and Windows 10/11. Some Linux distributions with Thunderbolt 3 support may also work, but official support includes those systems.
How can I clean and maintain the adapter?
To clean the adapter, power it off and disconnect it. Use a soft, dry, lint-free cloth to wipe the exterior. Do not use water, solvents, or abrasive cleaners, as they may damage the electronics.
What is the warranty on this product?
This product is backed by StarTech.com's 2-year warranty, ensuring coverage for defects in materials and workmanship. You also get free technical support during the warranty period.
