Product ID: CDP2DPMM3MB
This USB-C to DisplayPort cable lets you connect your Thunderbolt 3 or USB Type-C enabled device to a 4K DisplayPort monitor with just one cable, providing you with a convenient, clutter-free solution.
The USB C to DisplayPort adapter cable lets you harness the video capabilities that are built into your USB-C connection, to deliver the astonishing quality of Ultra HD to your 4K display and supporting resolutions up to 3840 x 2160.
Plus, the adapter is backward compatible with 1080p displays, which makes it a great accessory for home, office or other work environments.
At 9.8 ft. (3 m) in length, this monitor cable eliminates the need for excess adapters and cabling, ensuring a tidy, professional installation. For installations requiring a shorter connection we also offer a 6 ft. (1.8 m) (CDP2DPMM6B, CDP2DPMM6W) and a 3.3 ft. (1 m) (CDP2DPMM1MB, CDP2DPMM1MW) USB-C to DP cable, enabling you to choose the right cable length for your custom installation needs.
To ensure easy operation and installation, this USB C to DisplayPort cable works with both Windows and Mac computers and allows for plug-and-play installation, removing the need for any additional software or drivers.
CDP2DPMM3MB is backed by a 3-year StarTech.com warranty and free lifetime technical support.
Note: Your USB-C port must support DisplayPort over USB-C (DP Alt mode) in order to work with this adapter.

This device is plug and play. It does not use any drivers, and does not require any setup tasks other than plugging in the source (for example, a computer) and the destination (for example, a monitor).
When you troubleshoot issues with a video adapter, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue:
Video source (such as a DVD player or computer)
Video destination (such as a monitor or projector)
To test your setup components, try the following:
Use the cable, video adapter, video source, and video destination in another setup to see if the problem is with the components or the setup.
Use a different cable, video adapter, video source, and video destination in your setup to see if the problem persists. Ideally, you should test a component that you know works in another setup.
When you test your cables, it is recommended that you do the following:
Test each cable individually.
Use short cables when you are testing.
When you test the video source and video destination, it is recommended that you do the following:
Remove the video adapter from your setup and test to make sure that the video source and video destination work together without the video adapter.
Test to make sure that the video source and video destination work together at the resolution that you want to use.
Note: In order for your setup to work properly, the video source, adapter, and destination all need to support the resolution that you are using.
The error “Out of Range” normally means that the resolution being output by the computer is not compatible with the display. Try lowering the resolution to see if that helps resolve the issue. You may need to connect another monitor or restart the computer or source to accomplish this.
To output 4K to a DisplayPort display at 30Hz, your monitor must support the resolution and refresh rate. If your monitor also supports 4K at 60Hz (DP 1.2 or higher), you may also need to set the monitor to work at 30Hz.
To resolve this issue, use the buttons on your monitor to change the DisplayPort settings to DP1.1. For more information about how to change your monitor settings, refer to the website of the manufacturer of your monitor.
To output 4K to a DisplayPort display at 60Hz your monitor must support the resolution and refresh rate. If your monitor supports 4K at 60Hz (DP1.2 or higher) you may also need to set the monitor to work at 60Hz.
To resolve this issue, use the buttons on your monitor to change the DisplayPort settings to DP1.2. For more information about changing your monitor settings, refer to the website of the manufacturer of your monitor.

USB-C is a type of USB connector that is capable of supporting the following:
If using Thunderbolt 3 over USB-C, the connection is capable of additional features. For example, Thunderbolt 3 is capable of 40Gbps of total bandwidth. For more information, refer to the following FAQ: https://www.startech.com/faq/thunderbolt-3-port-capabilities.
Not all USB-C ports or devices are capable of supporting all of the features listed above, or all of the features at the maximum capabilities. If you require a specific USB-C feature, your USB host connection, cables, and device must all support the feature that you require. For more information about whether your components support specific USB-C features, refer to the information provided by the manufacturers.
This USB-C device requires that all of the following components support alternate modes:
If your host device includes a Thunderbolt™ 3 connection, this USB-C device will work with your host device.
For more information about the modes that your setup components support, refer to the information provided by the manufacturers.
