Special Notes / Requirements
Note For a dual-monitor configuration the host laptop must support MST.
Not all USB-C ports support the full functionality of the USB Type-C standard. Ensure that your host USB-C port supports USB Power Delivery 2.0 or 3.0 and DP alt mode.
The adapter can connect to a host laptop’s USB-C port that doesn’t support USB Power Delivery 2.0 or 3.0. However, in this configuration if a power adapter is connected to the multifunction adapter, it will not pass power through to your host laptop.
The multiport adapter provides limited Chrome support (no MST support; Ethernet only when using bus power).
The multiport adapter provides limited Android support (no MST support).
A 4K-capable display is required to achieve 3840 x 2160p resolution (4K is also known as 4K x 2K)
Video output capabilities are dependent on the video card and hardware specification of your connected laptop.
USB 3.0 is also known as USB 3.1 Gen 1; this connectivity standard offers speeds up to 5Gbps.
Your laptop may have specific requirements for charging. This USB-C multiport adapter supports USB Power Delivery 3.0, up to 100W. When using your laptop’s USB-C power adapter, the multiport adapter powers both the adapter (with attached peripherals) and your laptop - with up to 85W charging available for laptop charging. For more information on your laptop’s charging requirements, refer to the manufacturer of your laptop.
Through support of USB Power Delivery 3.0, the multiport adapter supports Fast Role Swap which prevents USB data disruption when you unplug to switch power sources (USB-C power adapter to bus power).
In USB 3.0 mode, the maximum Ethernet speed is 1000 Mbps. In USB 2.0 mode, the maximum Ethernet speed is 100 Mbps.

(5 stars) 4k@60Hz and charging

By: darkknight75
It took a few weeks searching for the right docking station for me. I need 4k@60Hz and power delivery. This enables me to interchange two laptops at the same monitor using just one single USB-C cable. This docking station is the first one that fulfilled my requirement. It is essential to read the docs. The device takes 15watts for itself. This means if you are using e.g. a 65w power supply, there will only be 50w available to the notebook. I solved the issue by buying an additional 112w USB-C power supply, offering enough reserves for both the power unit and the dock. Both notebooks charge fast. Highly recommended product if your notebook supports USB-C alt mode.

(4 stars) Work as intended

By: ulejas
This replaced the terrible docks that Dell is currently delivery to their customers. I won't start down that path. This dock works well, displays dual screens and can had the UltraSharp Dell monitors. Ethernet and USB works good. As the person that 1 stared this actually. I'm not sure how he/she actually thought it would charge the laptop too. That should have been obvious.

(1 star) Dual Display Great... Power No...

By: KevinD
i bought 4 of these for my work area as we upgraded laptops. Also have 4, 60w power supplies that work fine with the laptops. However, there is NO POWER DELIVERY when the USB C power supply is plugged into the Power delivery port. Not very useful at this point as the PC"s just bought have just 1 USB C port.

Response from StarTech.com:
Sam, Customer Support
Thank you for your review of DK30C2DAGPD. We're sorry that it's been having problems with power delivery. The dock itself is powered by your laptop's power adapter. It reserves a small amount of the power for itself, and the remainder goes to your laptop. If your laptop deems the power that gets through to be too little, it will not charge. Some laptop manufacturers have released updates to address this problem and allow laptops to accept lower amounts of power, so we recommend making sure your laptop is fully updated with the manufacturer's website. If you need further assistance, please reach out to our Technical Advisors at www.startech.com/support. We're available 24 hours a day, 5 days a week, to provide support.
