USB-C Multiport Video Adapter - 3-in-1 - 4K 30Hz - Black

Digital Visual Interface (DVI) is a video display interface that can contain different types of signaling, based on the application. DVI cables and ports are created using different connector types to identify what application they are intended to be used in. The connector types are identified by the number of pins on the DVI connector. DVI comes in the following five different connector types: 

• DVI-A (17 pin).
• DVI-D Single Link (19 pin).
• DVI-D Dual Link (25 pin).
• DVI-I Single Link (23 pin).
• DVI-I Dual Link (29 pin).

Single and Dual link DVI indicate the maximum resolution capabilities of the video source or video destination. The maximum resolutions are Single Link (1920 x 1080 @ 60Hz) and Dual Link (2560 x 1600 @ 60Hz).

Note: The maximum resolution of your video source and video destination are ultimately determined by the technical specifications of the devices. The connector type is not a definitive indicator of the maximum resolution.

DVI-A carries only analog (for example, VGA) with no digital component. DVI-D carries only digital video (for example, HDMI) with no analog component. DVI-I combines DVI-A and DVI-D connections to include both analog and digital components. A DVI-I port may be on either your video source or display, but whether or not a display carries either or both analog and digital sources depends on the technical specifications of your device.

USB-C is a type of USB connector that is capable of supporting the following:

• Data transfer speeds up to 10Gbps, if you use USB 3.1.
• Bi-directional power delivery up to 100W, if both the USB host connection and the device support it.
• Alternate modes, which deliver different types of data at different speeds. For example, DisplayPort Alternate Mode (DP Alt Mode).

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:

• The USB-C host connection (for example, a computer and its port)
• The USB-C cable
• The USB-C device (for example, a hard drive docking station)

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.

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 cables

• Video adapter

• 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.
