Cable Matters 201046 USB-C to 4K DisplayPort Multiport Adapter with Power Delivery
This USB-C Multiport Adapter is one of the first products on the market to support the new USB Power Delivery 3.0 standard. USB PD 3.0 ensures backwards compatibility with USB PD 2.0 and provides additional benefits including the Fast-Role Swap Mechanism (allows users to unplug power without interupting the connection) and Sorce-Coordinated Collision Avoidance (A more robust mechanism to avoid collisions when source and sink are negotiating power signals).
Symptom: The Multiport Adapter is not functioning properly on a Windows computer with Thunderbolt 3. Symptoms include no video, flickering video, and an unstable USB peripheral connection.
Solution: Update BIOS, firmware and drivers from the manufacturer website. For more details, refer to articles below:
Symptom: The Adapter is not recognized / one or more ports is not functional.
Unplug all cables and peripherals, restart the computer, and then reconnect everything.
Symptom: No signal when connecting to some monitors with DisplayPort input and output.
Some monitors such as Dell P2415Q and P2715Q 4K monitors have two DisplayPort connectors. One of the DisplayPort connectors is for DisplayPort input while the other one is for DisplayPort output. The DisplayPort output is designed for daisy chaining a second monitor. Please make sure to connect this adapter to the DisplayPort input.
Symptom: Computer is not charging or charges at a reduced speed.
This Multiport Adapter can pass up to 60 watts of power to the computer. Some computers require more than 60 watts. The power may be disabled through USB-C or charge at a reduced rate when only 60 watts of power is provided.
Use the original AC power adapter and USB-C cable that came with your computer when charging with this Multiport Adapter. Third party chargers may not be fully compliant with the USB specification. They may not charge properly or could potentially damage the Multiport Adapter or your computer.
Symptom: Unstable USB connection when using a peripheral such as an external hard drive.
This Multiport Adapter can be bus-powered by the USB-C port. Some USB peripherals may require more power than the USB-C port on the computer provides. This is more likely to happen when the Multiport Adapter is operating under full load with all ports in use. In this case, connect a USB-C cable and a USB-C AC power adapter to provide additional power.
Do not daisy chain another USB hub to this adapter through USB-A ports in order to connect more USB prepherals. It may overload the USB system or the power adapter and cause damage.
Symptom: DisplayPort does not work at full 4K 60Hz resolution.
The Multiport Adapter supports resolution up to 4K at 60Hz over a DisplayPort connection. A 4K-rated computer source, DisplayPort cable, and display are required.
Symptom: Ethernet disconnects with certain Dell computers.
Some Dell XPS and Precision models may contain a version of internal Wi-Fi adapters that interfere with the Ethernet connection over USB-C. This issue can be resolved by lowering the power output of the onboard Wi-Fi adapter.
