USB-C to HDMI Adapter - 4K 60Hz

When you troubleshoot issues with a USB 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 source

• Video destination

• USB video adapter

To test your setup components, try the following:

• Use the video cables, video source, video destination, and USB video adapter in another setup to see if the problem is with the components or the setup.

• Use a different video cable, video source, video destination, and USB video adapter 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 cables, video source, video destination, and USB video adapter, it is recommended that you do the following:

• Check Device Manager under Display adapters, Universal Serial Bus controllers, or USB Display adapters. To do this, press the Windows key + R, type devmgmt.msc, and press Enter to open Device Manager.

• If you do not see the USB video adapter in Device Manager, refer to the following FAQ: https://www.startech.com/support/faqs/technical-support?topic=expansion-cards#usb-cannot-detect-windows.

• If the device is listed with an error, reinstall the drivers following the instructions on the website.

• Check to see if your video card drivers are current. You can check what video card you have in Device Manager under Display adapters. It is recommended that you go directly to the video card manufacturer's website to check for the latest drivers.

• Check to see if the monitor is being detected by Windows.

To check to see if Windows is detecting the monitor using a computer that is running a version of Windows XP, do the following:

• Right-click on the desktop and click Properties.
• Click the Settings tab.
• If you see Drag the monitor icons to match the physical arrangement of your monitors, it means that Windows is detecting more than a single monitor. You can click the drop-down menu under Display to see which monitors are detected. This option is not available if Windows only detects a single monitor.

To check to see if Windows is detecting the monitor using a computer that is running a version of Windows Vista, Windows 7, or Windows 8, do the following:

• Right-click on the desktop and click Screen Resolution.
• You can click the drop-down menu under Display to see which monitors are detected.

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.

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. 

HDMI 2.0 offers some new features that were not available with the HDMI 1.4 standard, including the following:

• 4K resolution (4096x2160) at 60 Hz
• 21:9 aspect ratio support
• Four audio streams
• High-bandwidth Digital Content Protection (HDCP) version 2.2

Although HDMI 2.0 is backwards compatible with older HDMI standards, newer HDMI devices need to support HDCP 2.2 in order to display new content. If you use an HDMI device that only supports HDCP 2.0, an error will be displayed when you try to display content that has HDCP 2.2.

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.
